We're dividing 8151690 by 79 
We want to divide 8151690 by 79.

Going ahead to step 1:
When dividing 8 by 79, we get 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 79

On to step 2:
81 divided by 79 is 1 with a remainder of 2.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 79 from 81 and we're left with 2.
Append the next digit (5) from the dividend to 2 and continue with: 25 / 79

Step 3:
When dividing 25 by 79, we get 0 with a remainder of 25.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
If we take 0 away from 25, we end up with 25.
Bring next digit (1) of the dividend behind the 25 and repeat the process: 251 / 79

Going ahead to step 4:
79 can be fit into 251 3 times, resulting in a remainder of 14.
Put 3 as the next digit of the answer. 
Result so far: 103.0
Subtract 237 from 251 to get 14.
Bring next digit (6) of the dividend behind the 14 and repeat the process: 146 / 79

Step 5:
The number 79 fits into 146 1 times, leaving a remainder of 67.
Write down 1 as next digit of the result. 
Result so far: 1031.0
If we take 79 away from 146, we end up with 67.
Include the next digit (9) from the dividend after 67, then repeat: 679 / 79

Moving on to step 6:
679 divided by 79 is 8 with a remainder of 47.
Put 8 as the next digit of the answer. 
Result so far: 10318.0
Deduct 632 from 679 and we're left with 47.
Append the next digit (0) from the dividend to 47 and continue with: 470 / 79

Let's proceed to step 7:
When dividing 470 by 79, we get 5 with a remainder of 75.
Write down 5 as next digit of the result. 
Result so far: 103185.0
Subtracting 395 from 470 leaves us with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Step 8:
When dividing 750 by 79, we get 9 with a remainder of 39.
The number 9 becomes the next digit in our result. 
Result so far: 103185.9
If we subtract 711 from 750, we get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

On to step 9:
When dividing 390 by 79, we get 4 with a remainder of 74.
The number 4 becomes the next digit in our result. 
Result so far: 103185.94
If we subtract 316 from 390, we get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Let's proceed to step 10:
740 divided by 79 is 9 with a remainder of 29.
Put 9 as the next digit of the answer. 
Result so far: 103185.949
Subtracting 711 from 740 leaves us with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Step 11:
79 can be fit into 290 3 times, resulting in a remainder of 53.
Write down 3 as next digit of the result. 
Result so far: 103185.9493
If we take 237 away from 290, we end up with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Let's proceed to step 12:
When dividing 530 by 79, we get 6 with a remainder of 56.
Use 6 as the next digit of our solution. 
Result so far: 103185.94936
If we subtract 474 from 530, we get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Advancing to step 13:
79 goes into 560 7 times with a remainder of 7.
The next digit of our result is 7. 
Result so far: 103185.949367
The remainder is 7 after subtracting 553 from 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 14:
79 goes into 70 0 times with a remainder of 70.
Write down 0 as next digit of the result. 
Result so far: 103185.949367
Subtract 0 from 70 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Advancing to step 15:
700 divided by 79 is 8 with a remainder of 68.
The next digit of our result is 8. 
Result so far: 103185.94936708
The remainder is 68 after subtracting 632 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

After the division, we end up with 103185.94936708 and a remainder of 6.8e-08.
