We're dividing 72591912 by 77 
We want to figure out the number of times 72591912 can be divided by 77.

Let's proceed to step 1:
When dividing 7 by 77, we get 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Fetch the next digit (2) from the dividend, attach it to 7 and continue: 72 / 77

Let's proceed to step 2:
77 goes into 72 0 times with a remainder of 72.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 72, we get 72.
Append the next digit (5) from the dividend to 72 and continue with: 725 / 77

Going ahead to step 3:
When dividing 725 by 77, we get 9 with a remainder of 32.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
The remainder is 32 after subtracting 693 from 725.
Fetch the next digit (9) from the dividend, attach it to 32 and continue: 329 / 77

On to step 4:
77 can be fit into 329 4 times, resulting in a remainder of 21.
The next digit of our result is 4. 
Result so far: 94.0
Deduct 308 from 329 and we're left with 21.
Take the next digit (1) from the dividend and append it to 21, then repeat: 211 / 77

On to step 5:
The number 77 fits into 211 2 times, leaving a remainder of 57.
The next digit of our result is 2. 
Result so far: 942.0
The remainder is 57 after subtracting 154 from 211.
Fetch the next digit (9) from the dividend, attach it to 57 and continue: 579 / 77

Moving on to step 6:
77 can be fit into 579 7 times, resulting in a remainder of 40.
Write down 7 as next digit of the result. 
Result so far: 9427.0
Deduct 539 from 579 and we're left with 40.
Bring next digit (1) of the dividend behind the 40 and repeat the process: 401 / 77

Step 7:
401 divided by 77 is 5 with a remainder of 16.
Write down 5 as next digit of the result. 
Result so far: 94275.0
Deduct 385 from 401 and we're left with 16.
Bring next digit (2) of the dividend behind the 16 and repeat the process: 162 / 77

Step 8:
When dividing 162 by 77, we get 2 with a remainder of 8.
The next digit of our result is 2. 
Result so far: 942752.0
If we subtract 154 from 162, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 9:
77 goes into 80 1 times with a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 942752.1
Subtract 77 from 80 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 10:
The number 77 fits into 30 0 times, leaving a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 942752.1
If we subtract 0 from 30, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 11:
300 divided by 77 is 3 with a remainder of 69.
Put 3 as the next digit of the answer. 
Result so far: 942752.103
If we take 231 away from 300, we end up with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Going ahead to step 12:
If we divide 690 by 77, we get 8 and a remainder of 74.
Record the quotient 8 as the next digit in the result. 
Result so far: 942752.1038
The remainder is 74 after subtracting 616 from 690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Going ahead to step 13:
The number 77 fits into 740 9 times, leaving a remainder of 47.
The number 9 becomes the next digit in our result. 
Result so far: 942752.10389
Deduct 693 from 740 and we're left with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

On to step 14:
470 divided by 77 is 6 with a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 942752.103896
Subtract 462 from 470 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 15:
When dividing 80 by 77, we get 1 with a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 942752.1038961
If we subtract 77 from 80, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 16:
77 can be fit into 30 0 times, resulting in a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 942752.1038961
If we take 0 away from 30, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

In conclusion, the division gives 942752.1038961 with a balance of 3e-08.
