Let's divide 63102172 by 797
We want to divide 63102172 by 797.

Step 1:
797 goes into 6 0 times with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Fetch the next digit (3) from the dividend, attach it to 6 and continue: 63 / 797

Moving on to step 2:
797 goes into 63 0 times with a remainder of 63.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 63 to get 63.
Append the next digit (1) from the dividend to 63 and continue with: 631 / 797

Advancing to step 3:
If we divide 631 by 797, we get 0 and a remainder of 631.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 631, we get 631.
Include the next digit (0) from the dividend after 631, then repeat: 6310 / 797

On to step 4:
797 can be fit into 6310 7 times, resulting in a remainder of 731.
The next digit of our result is 7. 
Result so far: 7.0
Subtract 5579 from 6310 to get 731.
Include the next digit (2) from the dividend after 731, then repeat: 7312 / 797

On to step 5:
797 can be fit into 7312 9 times, resulting in a remainder of 139.
Record the quotient 9 as the next digit in the result. 
Result so far: 79.0
If we subtract 7173 from 7312, we get 139.
Grab the next digit (1) from the dividend, add it to 139, then carry on: 1391 / 797

Step 6:
The number 797 fits into 1391 1 times, leaving a remainder of 594.
Put 1 as the next digit of the answer. 
Result so far: 791.0
Subtracting 797 from 1391 leaves us with 594.
Grab the next digit (7) from the dividend, add it to 594, then carry on: 5947 / 797

On to step 7:
When dividing 5947 by 797, we get 7 with a remainder of 368.
Write down 7 as next digit of the result. 
Result so far: 7917.0
The remainder is 368 after subtracting 5579 from 5947.
Include the next digit (2) from the dividend after 368, then repeat: 3682 / 797

Moving on to step 8:
The number 797 fits into 3682 4 times, leaving a remainder of 494.
Record the quotient 4 as the next digit in the result. 
Result so far: 79174.0
Deduct 3188 from 3682 and we're left with 494.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4940, and continue the process.

Going ahead to step 9:
797 can be fit into 4940 6 times, resulting in a remainder of 158.
Use 6 as the next digit of our solution. 
Result so far: 79174.6
If we subtract 4782 from 4940, we get 158.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1580, and continue the process.

Let's proceed to step 10:
The number 797 fits into 1580 1 times, leaving a remainder of 783.
Use 1 as the next digit of our solution. 
Result so far: 79174.61
Subtract 797 from 1580 to get 783.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7830, and continue the process.

Step 11:
797 goes into 7830 9 times with a remainder of 657.
Write down 9 as next digit of the result. 
Result so far: 79174.619
The remainder is 657 after subtracting 7173 from 7830.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6570, and continue the process.

Moving on to step 12:
797 goes into 6570 8 times with a remainder of 194.
Use 8 as the next digit of our solution. 
Result so far: 79174.6198
If we subtract 6376 from 6570, we get 194.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1940, and continue the process.

Step 13:
797 goes into 1940 2 times with a remainder of 346.
The number 2 becomes the next digit in our result. 
Result so far: 79174.61982
Deduct 1594 from 1940 and we're left with 346.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3460, and continue the process.

Let's proceed to step 14:
The number 797 fits into 3460 4 times, leaving a remainder of 272.
Write down 4 as next digit of the result. 
Result so far: 79174.619824
Subtracting 3188 from 3460 leaves us with 272.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

On to step 15:
The number 797 fits into 2720 3 times, leaving a remainder of 329.
Use 3 as the next digit of our solution. 
Result so far: 79174.6198243
If we subtract 2391 from 2720, we get 329.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3290, and continue the process.

On to step 16:
If we divide 3290 by 797, we get 4 and a remainder of 102.
Write down 4 as next digit of the result. 
Result so far: 79174.61982434
If we subtract 3188 from 3290, we get 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

The final result is 79174.61982434 with a remainder of 1.02e-07.
