We divide 53705656 by 645
We want to figure out the number of times 53705656 can be divided by 645.

On to step 1:
645 goes into 5 0 times with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Append the next digit (3) from the dividend to 5 and continue with: 53 / 645

Going ahead to step 2:
53 divided by 645 is 0 with a remainder of 53.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 53, we get 53.
Fetch the next digit (7) from the dividend, attach it to 53 and continue: 537 / 645

Going ahead to step 3:
When dividing 537 by 645, we get 0 with a remainder of 537.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 537, we end up with 537.
Append the next digit (0) from the dividend to 537 and continue with: 5370 / 645

Advancing to step 4:
When dividing 5370 by 645, we get 8 with a remainder of 210.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Subtract 5160 from 5370 to get 210.
Append the next digit (5) from the dividend to 210 and continue with: 2105 / 645

Let's proceed to step 5:
645 goes into 2105 3 times with a remainder of 170.
Write down 3 as next digit of the result. 
Result so far: 83.0
Deduct 1935 from 2105 and we're left with 170.
Take the next digit (6) from the dividend and append it to 170, then repeat: 1706 / 645

Advancing to step 6:
645 can be fit into 1706 2 times, resulting in a remainder of 416.
Write down 2 as next digit of the result. 
Result so far: 832.0
The remainder is 416 after subtracting 1290 from 1706.
Grab the next digit (5) from the dividend, add it to 416, then carry on: 4165 / 645

Let's proceed to step 7:
645 goes into 4165 6 times with a remainder of 295.
Record the quotient 6 as the next digit in the result. 
Result so far: 8326.0
If we take 3870 away from 4165, we end up with 295.
Take the next digit (6) from the dividend and append it to 295, then repeat: 2956 / 645

Going ahead to step 8:
2956 divided by 645 is 4 with a remainder of 376.
Record the quotient 4 as the next digit in the result. 
Result so far: 83264.0
Subtract 2580 from 2956 to get 376.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3760, and continue the process.

Advancing to step 9:
645 goes into 3760 5 times with a remainder of 535.
The number 5 becomes the next digit in our result. 
Result so far: 83264.5
Subtract 3225 from 3760 to get 535.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5350, and continue the process.

On to step 10:
645 goes into 5350 8 times with a remainder of 190.
Record the quotient 8 as the next digit in the result. 
Result so far: 83264.58
The remainder is 190 after subtracting 5160 from 5350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Going ahead to step 11:
645 goes into 1900 2 times with a remainder of 610.
Record the quotient 2 as the next digit in the result. 
Result so far: 83264.582
If we take 1290 away from 1900, we end up with 610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6100, and continue the process.

On to step 12:
The number 645 fits into 6100 9 times, leaving a remainder of 295.
The next digit of our result is 9. 
Result so far: 83264.5829
Deduct 5805 from 6100 and we're left with 295.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2950, and continue the process.

Let's proceed to step 13:
If we divide 2950 by 645, we get 4 and a remainder of 370.
The next digit of our result is 4. 
Result so far: 83264.58294
The remainder is 370 after subtracting 2580 from 2950.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

Moving on to step 14:
645 goes into 3700 5 times with a remainder of 475.
Write down 5 as next digit of the result. 
Result so far: 83264.582945
The remainder is 475 after subtracting 3225 from 3700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4750, and continue the process.

Moving on to step 15:
645 can be fit into 4750 7 times, resulting in a remainder of 235.
Put 7 as the next digit of the answer. 
Result so far: 83264.5829457
Deduct 4515 from 4750 and we're left with 235.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2350, and continue the process.

Step 16:
If we divide 2350 by 645, we get 3 and a remainder of 415.
Put 3 as the next digit of the answer. 
Result so far: 83264.58294573
Deduct 1935 from 2350 and we're left with 415.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4150, and continue the process.

After the division, we end up with 83264.58294573 and a remainder of 4.15e-07.
