We look at the division of 63406501 by 791 
Let's see how many times 791 fits into 63406501.

Advancing to step 1:
791 can be fit into 6 0 times, resulting in a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Bring next digit (3) of the dividend behind the 6 and repeat the process: 63 / 791

Advancing to step 2:
791 goes into 63 0 times with a remainder of 63.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 63 and we're left with 63.
Grab the next digit (4) from the dividend, add it to 63, then carry on: 634 / 791

Moving on to step 3:
If we divide 634 by 791, we get 0 and a remainder of 634.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 634 to get 634.
Take the next digit (0) from the dividend and append it to 634, then repeat: 6340 / 791

Advancing to step 4:
When dividing 6340 by 791, we get 8 with a remainder of 12.
The next digit of our result is 8. 
Result so far: 8.0
Subtracting 6328 from 6340 leaves us with 12.
Append the next digit (6) from the dividend to 12 and continue with: 126 / 791

Going ahead to step 5:
791 can be fit into 126 0 times, resulting in a remainder of 126.
Use 0 as the next digit of our solution. 
Result so far: 80.0
If we take 0 away from 126, we end up with 126.
Fetch the next digit (5) from the dividend, attach it to 126 and continue: 1265 / 791

Moving on to step 6:
The number 791 fits into 1265 1 times, leaving a remainder of 474.
The number 1 becomes the next digit in our result. 
Result so far: 801.0
Deduct 791 from 1265 and we're left with 474.
Take the next digit (0) from the dividend and append it to 474, then repeat: 4740 / 791

Let's proceed to step 7:
791 can be fit into 4740 5 times, resulting in a remainder of 785.
Record the quotient 5 as the next digit in the result. 
Result so far: 8015.0
If we take 3955 away from 4740, we end up with 785.
Take the next digit (1) from the dividend and append it to 785, then repeat: 7851 / 791

Advancing to step 8:
If we divide 7851 by 791, we get 9 and a remainder of 732.
Write down 9 as next digit of the result. 
Result so far: 80159.0
If we subtract 7119 from 7851, we get 732.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7320, and continue the process.

Going ahead to step 9:
The number 791 fits into 7320 9 times, leaving a remainder of 201.
Write down 9 as next digit of the result. 
Result so far: 80159.9
Deduct 7119 from 7320 and we're left with 201.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2010, and continue the process.

Step 10:
When dividing 2010 by 791, we get 2 with a remainder of 428.
Write down 2 as next digit of the result. 
Result so far: 80159.92
Deduct 1582 from 2010 and we're left with 428.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4280, and continue the process.

Let's proceed to step 11:
When dividing 4280 by 791, we get 5 with a remainder of 325.
The number 5 becomes the next digit in our result. 
Result so far: 80159.925
Subtracting 3955 from 4280 leaves us with 325.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3250, and continue the process.

Step 12:
If we divide 3250 by 791, we get 4 and a remainder of 86.
The next digit of our result is 4. 
Result so far: 80159.9254
The remainder is 86 after subtracting 3164 from 3250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Advancing to step 13:
If we divide 860 by 791, we get 1 and a remainder of 69.
Write down 1 as next digit of the result. 
Result so far: 80159.92541
Subtracting 791 from 860 leaves us 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 14:
The number 791 fits into 690 0 times, leaving a remainder of 690.
Record the quotient 0 as the next digit in the result. 
Result so far: 80159.92541
If we take 0 away from 690, we end up with 690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6900, and continue the process.

Moving on to step 15:
791 can be fit into 6900 8 times, resulting in a remainder of 572.
Record the quotient 8 as the next digit in the result. 
Result so far: 80159.9254108
Subtracting 6328 from 6900 leaves us with 572.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5720, and continue the process.

Advancing to step 16:
791 goes into 5720 7 times with a remainder of 183.
Put 7 as the next digit of the answer. 
Result so far: 80159.92541087
If we subtract 5537 from 5720, we get 183.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1830, and continue the process.

The quotient of the division is 80159.92541087, and the remainder is 1.83e-07.
