Let's divide 51076404 by 876
We want to divide 51076404 by 876.

On to step 1:
If we divide 5 by 876, we get 0 and a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Bring next digit (1) of the dividend behind the 5 and repeat the process: 51 / 876

Step 2:
876 goes into 51 0 times with a remainder of 51.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 51 and we're left with 51.
Include the next digit (0) from the dividend after 51, then repeat: 510 / 876

Step 3:
If we divide 510 by 876, we get 0 and a remainder of 510.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 510, we get 510.
Fetch the next digit (7) from the dividend, attach it to 510 and continue: 5107 / 876

On to step 4:
The number 876 fits into 5107 5 times, leaving a remainder of 727.
Use 5 as the next digit of our solution. 
Result so far: 5.0
If we take 4380 away from 5107, we end up with 727.
Append the next digit (6) from the dividend to 727 and continue with: 7276 / 876

Going ahead to step 5:
The number 876 fits into 7276 8 times, leaving a remainder of 268.
Write down 8 as next digit of the result. 
Result so far: 58.0
Subtracting 7008 from 7276 leaves us with 268.
Take the next digit (4) from the dividend and append it to 268, then repeat: 2684 / 876

Let's proceed to step 6:
876 can be fit into 2684 3 times, resulting in a remainder of 56.
Record the quotient 3 as the next digit in the result. 
Result so far: 583.0
If we subtract 2628 from 2684, we get 56.
Fetch the next digit (0) from the dividend, attach it to 56 and continue: 560 / 876

Moving on to step 7:
876 goes into 560 0 times with a remainder of 560.
Record the quotient 0 as the next digit in the result. 
Result so far: 5830.0
The remainder is 560 after subtracting 0 from 560.
Take the next digit (4) from the dividend and append it to 560, then repeat: 5604 / 876

Step 8:
When dividing 5604 by 876, we get 6 with a remainder of 348.
The next digit of our result is 6. 
Result so far: 58306.0
If we subtract 5256 from 5604, we get 348.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3480, and continue the process.

Moving on to step 9:
876 goes into 3480 3 times with a remainder of 852.
Use 3 as the next digit of our solution. 
Result so far: 58306.3
The remainder is 852 after subtracting 2628 from 3480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8520, and continue the process.

Moving on to step 10:
If we divide 8520 by 876, we get 9 and a remainder of 636.
Put 9 as the next digit of the answer. 
Result so far: 58306.39
Deduct 7884 from 8520 and we're left with 636.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6360, and continue the process.

Step 11:
When dividing 6360 by 876, we get 7 with a remainder of 228.
The number 7 becomes the next digit in our result. 
Result so far: 58306.397
Deduct 6132 from 6360 and we're left with 228.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2280, and continue the process.

On to step 12:
If we divide 2280 by 876, we get 2 and a remainder of 528.
Record the quotient 2 as the next digit in the result. 
Result so far: 58306.3972
If we take 1752 away from 2280, we end up with 528.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5280, and continue the process.

On to step 13:
876 can be fit into 5280 6 times, resulting in a remainder of 24.
Put 6 as the next digit of the answer. 
Result so far: 58306.39726
If we take 5256 away from 5280, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 14:
240 divided by 876 is 0 with a remainder of 240.
Use 0 as the next digit of our solution. 
Result so far: 58306.39726
The remainder is 240 after subtracting 0 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Step 15:
876 can be fit into 2400 2 times, resulting in a remainder of 648.
Record the quotient 2 as the next digit in the result. 
Result so far: 58306.3972602
If we subtract 1752 from 2400, we get 648.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6480, and continue the process.

Moving on to step 16:
6480 divided by 876 is 7 with a remainder of 348.
The next digit of our result is 7. 
Result so far: 58306.39726027
Deduct 6132 from 6480 and we're left with 348.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3480, and continue the process.

After the division, we end up with 58306.39726027 and a remainder of 3.48e-07.
