We divide 79523645 by 645
We want to figure out the number of times 79523645 can be divided by 645.

Moving on to step 1:
645 goes into 7 0 times with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Take the next digit (9) from the dividend and append it to 7, then repeat: 79 / 645

On to step 2:
The number 645 fits into 79 0 times, leaving a remainder of 79.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 79 to get 79.
Append the next digit (5) from the dividend to 79 and continue with: 795 / 645

Let's proceed to step 3:
When dividing 795 by 645, we get 1 with a remainder of 150.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 645 from 795 and we're left with 150.
Include the next digit (2) from the dividend after 150, then repeat: 1502 / 645

On to step 4:
When dividing 1502 by 645, we get 2 with a remainder of 212.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
Subtracting 1290 from 1502 leaves us with 212.
Include the next digit (3) from the dividend after 212, then repeat: 2123 / 645

Let's proceed to step 5:
645 can be fit into 2123 3 times, resulting in a remainder of 188.
Use 3 as the next digit of our solution. 
Result so far: 123.0
If we subtract 1935 from 2123, we get 188.
Include the next digit (6) from the dividend after 188, then repeat: 1886 / 645

On to step 6:
645 goes into 1886 2 times with a remainder of 596.
Record the quotient 2 as the next digit in the result. 
Result so far: 1232.0
If we take 1290 away from 1886, we end up with 596.
Fetch the next digit (4) from the dividend, attach it to 596 and continue: 5964 / 645

On to step 7:
645 can be fit into 5964 9 times, resulting in a remainder of 159.
Write down 9 as next digit of the result. 
Result so far: 12329.0
If we take 5805 away from 5964, we end up with 159.
Grab the next digit (5) from the dividend, add it to 159, then carry on: 1595 / 645

Moving on to step 8:
The number 645 fits into 1595 2 times, leaving a remainder of 305.
The next digit of our result is 2. 
Result so far: 123292.0
Subtracting 1290 from 1595 leaves us with 305.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3050, and continue the process.

Advancing to step 9:
When dividing 3050 by 645, we get 4 with a remainder of 470.
Write down 4 as next digit of the result. 
Result so far: 123292.4
If we subtract 2580 from 3050, we get 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4700, and continue the process.

Advancing to step 10:
645 can be fit into 4700 7 times, resulting in a remainder of 185.
Record the quotient 7 as the next digit in the result. 
Result so far: 123292.47
If we take 4515 away from 4700, we end up with 185.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

Moving on to step 11:
1850 divided by 645 is 2 with a remainder of 560.
Record the quotient 2 as the next digit in the result. 
Result so far: 123292.472
The remainder is 560 after subtracting 1290 from 1850.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Moving on to step 12:
The number 645 fits into 5600 8 times, leaving a remainder of 440.
Write down 8 as next digit of the result. 
Result so far: 123292.4728
The remainder is 440 after subtracting 5160 from 5600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Moving on to step 13:
645 can be fit into 4400 6 times, resulting in a remainder of 530.
The next digit of our result is 6. 
Result so far: 123292.47286
Deduct 3870 from 4400 and we're left with 530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5300, and continue the process.

Let's proceed to step 14:
5300 divided by 645 is 8 with a remainder of 140.
The number 8 becomes the next digit in our result. 
Result so far: 123292.472868
Subtract 5160 from 5300 to get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Moving on to step 15:
645 goes into 1400 2 times with a remainder of 110.
Use 2 as the next digit of our solution. 
Result so far: 123292.4728682
Subtracting 1290 from 1400 leaves us with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Going ahead to step 16:
If we divide 1100 by 645, we get 1 and a remainder of 455.
Record the quotient 1 as the next digit in the result. 
Result so far: 123292.47286821
If we take 645 away from 1100, we end up with 455.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4550, and continue the process.

The final result is 123292.47286821 with a remainder of 4.55e-07.
