Let's divide 66734623 by 851
Our goal is to divide 66734623 by 851.

On to step 1:
6 divided by 851 is 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 851

Moving on to step 2:
66 divided by 851 is 0 with a remainder of 66.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 66, we get 66.
Bring next digit (7) of the dividend behind the 66 and repeat the process: 667 / 851

Going ahead to step 3:
When dividing 667 by 851, we get 0 with a remainder of 667.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 667 leaves us with 667.
Include the next digit (3) from the dividend after 667, then repeat: 6673 / 851

Advancing to step 4:
The number 851 fits into 6673 7 times, leaving a remainder of 716.
Write down 7 as next digit of the result. 
Result so far: 7.0
Deduct 5957 from 6673 and we're left with 716.
Include the next digit (4) from the dividend after 716, then repeat: 7164 / 851

Going ahead to step 5:
7164 divided by 851 is 8 with a remainder of 356.
Use 8 as the next digit of our solution. 
Result so far: 78.0
Subtract 6808 from 7164 to get 356.
Bring next digit (6) of the dividend behind the 356 and repeat the process: 3566 / 851

Going ahead to step 6:
If we divide 3566 by 851, we get 4 and a remainder of 162.
The number 4 becomes the next digit in our result. 
Result so far: 784.0
Subtract 3404 from 3566 to get 162.
Bring next digit (2) of the dividend behind the 162 and repeat the process: 1622 / 851

Let's proceed to step 7:
When dividing 1622 by 851, we get 1 with a remainder of 771.
The number 1 becomes the next digit in our result. 
Result so far: 7841.0
The remainder is 771 after subtracting 851 from 1622.
Bring next digit (3) of the dividend behind the 771 and repeat the process: 7713 / 851

Advancing to step 8:
851 goes into 7713 9 times with a remainder of 54.
The next digit of our result is 9. 
Result so far: 78419.0
If we subtract 7659 from 7713, we get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Moving on to step 9:
When dividing 540 by 851, we get 0 with a remainder of 540.
The next digit of our result is 0. 
Result so far: 78419.0
Subtracting 0 from 540 leaves us with 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5400, and continue the process.

Going ahead to step 10:
When dividing 5400 by 851, we get 6 with a remainder of 294.
Use 6 as the next digit of our solution. 
Result so far: 78419.06
Subtracting 5106 from 5400 leaves us with 294.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2940, and continue the process.

Moving on to step 11:
The number 851 fits into 2940 3 times, leaving a remainder of 387.
Put 3 as the next digit of the answer. 
Result so far: 78419.063
Subtracting 2553 from 2940 leaves us with 387.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3870, and continue the process.

Moving on to step 12:
851 can be fit into 3870 4 times, resulting in a remainder of 466.
The next digit of our result is 4. 
Result so far: 78419.0634
If we subtract 3404 from 3870, we get 466.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4660, and continue the process.

Let's proceed to step 13:
If we divide 4660 by 851, we get 5 and a remainder of 405.
The number 5 becomes the next digit in our result. 
Result so far: 78419.06345
If we take 4255 away from 4660, we end up with 405.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4050, and continue the process.

On to step 14:
4050 divided by 851 is 4 with a remainder of 646.
Write down 4 as next digit of the result. 
Result so far: 78419.063454
Subtract 3404 from 4050 to get 646.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6460, and continue the process.

Going ahead to step 15:
If we divide 6460 by 851, we get 7 and a remainder of 503.
Use 7 as the next digit of our solution. 
Result so far: 78419.0634547
If we subtract 5957 from 6460, 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.

On to step 16:
The number 851 fits into 5030 5 times, leaving a remainder of 775.
Put 5 as the next digit of the answer. 
Result so far: 78419.06345475
If we subtract 4255 from 5030, we get 775.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7750, and continue the process.

Our division results in 78419.06345475 with a remaining 7.75e-07.
