We look at the division of 50399090 by 872 
We want to divide 50399090 by 872.

Moving on to step 1:
872 goes into 5 0 times with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Append the next digit (0) from the dividend to 5 and continue with: 50 / 872

Advancing to step 2:
The number 872 fits into 50 0 times, leaving a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 50 to get 50.
Append the next digit (3) from the dividend to 50 and continue with: 503 / 872

Advancing to step 3:
872 goes into 503 0 times with a remainder of 503.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 503 and we're left with 503.
Take the next digit (9) from the dividend and append it to 503, then repeat: 5039 / 872

Going ahead to step 4:
5039 divided by 872 is 5 with a remainder of 679.
Put 5 as the next digit of the answer. 
Result so far: 5.0
If we take 4360 away from 5039, we end up with 679.
Bring next digit (9) of the dividend behind the 679 and repeat the process: 6799 / 872

On to step 5:
When dividing 6799 by 872, we get 7 with a remainder of 695.
The next digit of our result is 7. 
Result so far: 57.0
Subtract 6104 from 6799 to get 695.
Take the next digit (0) from the dividend and append it to 695, then repeat: 6950 / 872

On to step 6:
872 goes into 6950 7 times with a remainder of 846.
Write down 7 as next digit of the result. 
Result so far: 577.0
If we subtract 6104 from 6950, we get 846.
Grab the next digit (9) from the dividend, add it to 846, then carry on: 8469 / 872

Going ahead to step 7:
8469 divided by 872 is 9 with a remainder of 621.
Use 9 as the next digit of our solution. 
Result so far: 5779.0
Deduct 7848 from 8469 and we're left with 621.
Include the next digit (0) from the dividend after 621, then repeat: 6210 / 872

Step 8:
When dividing 6210 by 872, we get 7 with a remainder of 106.
Use 7 as the next digit of our solution. 
Result so far: 57797.0
If we subtract 6104 from 6210, we get 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

On to step 9:
The number 872 fits into 1060 1 times, leaving a remainder of 188.
Use 1 as the next digit of our solution. 
Result so far: 57797.1
Subtract 872 from 1060 to get 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

Let's proceed to step 10:
1880 divided by 872 is 2 with a remainder of 136.
Use 2 as the next digit of our solution. 
Result so far: 57797.12
Subtract 1744 from 1880 to get 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Going ahead to step 11:
If we divide 1360 by 872, we get 1 and a remainder of 488.
The next digit of our result is 1. 
Result so far: 57797.121
Subtract 872 from 1360 to get 488.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4880, and continue the process.

Advancing to step 12:
872 goes into 4880 5 times with a remainder of 520.
Put 5 as the next digit of the answer. 
Result so far: 57797.1215
Deduct 4360 from 4880 and we're left with 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

Let's proceed to step 13:
872 goes into 5200 5 times with a remainder of 840.
Record the quotient 5 as the next digit in the result. 
Result so far: 57797.12155
Deduct 4360 from 5200 and we're left with 840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8400, and continue the process.

After the division, we end up with 57797.12155 and a remainder of 0.00084.
