Let's divide 77386098 by 851
We want to divide 77386098 by 851.

Moving on to step 1:
851 can be fit into 7 0 times, resulting in a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Take the next digit (7) from the dividend and append it to 7, then repeat: 77 / 851

Step 2:
77 divided by 851 is 0 with a remainder of 77.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 77 to get 77.
Include the next digit (3) from the dividend after 77, then repeat: 773 / 851

Let's proceed to step 3:
If we divide 773 by 851, we get 0 and a remainder of 773.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 773 after subtracting 0 from 773.
Append the next digit (8) from the dividend to 773 and continue with: 7738 / 851

Advancing to step 4:
If we divide 7738 by 851, we get 9 and a remainder of 79.
Write down 9 as next digit of the result. 
Result so far: 9.0
Subtracting 7659 from 7738 leaves us with 79.
Bring next digit (6) of the dividend behind the 79 and repeat the process: 796 / 851

On to step 5:
When dividing 796 by 851, we get 0 with a remainder of 796.
Use 0 as the next digit of our solution. 
Result so far: 90.0
The remainder is 796 after subtracting 0 from 796.
Fetch the next digit (0) from the dividend, attach it to 796 and continue: 7960 / 851

Advancing to step 6:
The number 851 fits into 7960 9 times, leaving a remainder of 301.
The next digit of our result is 9. 
Result so far: 909.0
The remainder is 301 after subtracting 7659 from 7960.
Fetch the next digit (9) from the dividend, attach it to 301 and continue: 3019 / 851

Going ahead to step 7:
3019 divided by 851 is 3 with a remainder of 466.
The number 3 becomes the next digit in our result. 
Result so far: 9093.0
If we subtract 2553 from 3019, we get 466.
Grab the next digit (8) from the dividend, add it to 466, then carry on: 4668 / 851

Let's proceed to step 8:
The number 851 fits into 4668 5 times, leaving a remainder of 413.
Put 5 as the next digit of the answer. 
Result so far: 90935.0
If we subtract 4255 from 4668, we get 413.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4130, and continue the process.

On to step 9:
If we divide 4130 by 851, we get 4 and a remainder of 726.
The number 4 becomes the next digit in our result. 
Result so far: 90935.4
If we subtract 3404 from 4130, we get 726.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7260, and continue the process.

Step 10:
When dividing 7260 by 851, we get 8 with a remainder of 452.
Write down 8 as next digit of the result. 
Result so far: 90935.48
Subtracting 6808 from 7260 leaves us with 452.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4520, and continue the process.

Going ahead to step 11:
851 goes into 4520 5 times with a remainder of 265.
Use 5 as the next digit of our solution. 
Result so far: 90935.485
Subtracting 4255 from 4520 leaves us with 265.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2650, and continue the process.

Going ahead to step 12:
2650 divided by 851 is 3 with a remainder of 97.
The number 3 becomes the next digit in our result. 
Result so far: 90935.4853
If we take 2553 away from 2650, we end up with 97.
Since there are no more digits in the dividend, we add a zero to the remainder making it 970, and continue the process.

Advancing to step 13:
851 goes into 970 1 times with a remainder of 119.
The next digit of our result is 1. 
Result so far: 90935.48531
Subtracting 851 from 970 leaves us with 119.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1190, and continue the process.

Moving on to step 14:
851 can be fit into 1190 1 times, resulting in a remainder of 339.
Use 1 as the next digit of our solution. 
Result so far: 90935.485311
If we take 851 away from 1190, we end up with 339.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3390, and continue the process.

The final outcome is 90935.485311, with a leftover of 3.39e-05.
