Let's divide 80871897 by 779
We want to figure out the number of times 80871897 can be divided by 779.

On to step 1:
The number 779 fits into 8 0 times, leaving a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Bring next digit (0) of the dividend behind the 8 and repeat the process: 80 / 779

Going ahead to step 2:
The number 779 fits into 80 0 times, leaving a remainder of 80.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 80 to get 80.
Append the next digit (8) from the dividend to 80 and continue with: 808 / 779

On to step 3:
If we divide 808 by 779, we get 1 and a remainder of 29.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 779 away from 808, we end up with 29.
Include the next digit (7) from the dividend after 29, then repeat: 297 / 779

Advancing to step 4:
If we divide 297 by 779, we get 0 and a remainder of 297.
Put 0 as the next digit of the answer. 
Result so far: 10.0
Subtract 0 from 297 to get 297.
Take the next digit (1) from the dividend and append it to 297, then repeat: 2971 / 779

Moving on to step 5:
779 can be fit into 2971 3 times, resulting in a remainder of 634.
Record the quotient 3 as the next digit in the result. 
Result so far: 103.0
Subtracting 2337 from 2971 leaves us with 634.
Include the next digit (8) from the dividend after 634, then repeat: 6348 / 779

Let's proceed to step 6:
779 can be fit into 6348 8 times, resulting in a remainder of 116.
Put 8 as the next digit of the answer. 
Result so far: 1038.0
Subtract 6232 from 6348 to get 116.
Include the next digit (9) from the dividend after 116, then repeat: 1169 / 779

On to step 7:
When dividing 1169 by 779, we get 1 with a remainder of 390.
Put 1 as the next digit of the answer. 
Result so far: 10381.0
Subtracting 779 from 1169 leaves us with 390.
Append the next digit (7) from the dividend to 390 and continue with: 3907 / 779

Moving on to step 8:
When dividing 3907 by 779, we get 5 with a remainder of 12.
Write down 5 as next digit of the result. 
Result so far: 103815.0
Deduct 3895 from 3907 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 9:
779 can be fit into 120 0 times, resulting in a remainder of 120.
The next digit of our result is 0. 
Result so far: 103815.0
Subtracting 0 from 120 leaves us with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Step 10:
The number 779 fits into 1200 1 times, leaving a remainder of 421.
The number 1 becomes the next digit in our result. 
Result so far: 103815.01
If we subtract 779 from 1200, we get 421.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4210, and continue the process.

Advancing to step 11:
When dividing 4210 by 779, we get 5 with a remainder of 315.
Write down 5 as next digit of the result. 
Result so far: 103815.015
Subtract 3895 from 4210 to get 315.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3150, and continue the process.

Step 12:
If we divide 3150 by 779, we get 4 and a remainder of 34.
Record the quotient 4 as the next digit in the result. 
Result so far: 103815.0154
Deduct 3116 from 3150 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Let's proceed to step 13:
779 can be fit into 340 0 times, resulting in a remainder of 340.
Write down 0 as next digit of the result. 
Result so far: 103815.0154
Deduct 0 from 340 and we're left with 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Let's proceed to step 14:
If we divide 3400 by 779, we get 4 and a remainder of 284.
Write down 4 as next digit of the result. 
Result so far: 103815.015404
Deduct 3116 from 3400 and we're left with 284.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2840, and continue the process.

Step 15:
When dividing 2840 by 779, we get 3 with a remainder of 503.
Use 3 as the next digit of our solution. 
Result so far: 103815.0154043
If we subtract 2337 from 2840, we get 503.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5030, and continue the process.

Step 16:
779 goes into 5030 6 times with a remainder of 356.
Use 6 as the next digit of our solution. 
Result so far: 103815.01540436
Subtract 4674 from 5030 to get 356.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3560, and continue the process.

The quotient of the division is 103815.01540436, and the remainder is 3.56e-07.
