We look at the division of 51289136 by 627 
We want to divide 51289136 by 627.

Going ahead to step 1:
If we divide 5 by 627, we get 0 and a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Bring next digit (1) of the dividend behind the 5 and repeat the process: 51 / 627

Moving on to step 2:
If we divide 51 by 627, we get 0 and a remainder of 51.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 51 and we're left with 51.
Bring next digit (2) of the dividend behind the 51 and repeat the process: 512 / 627

Step 3:
627 goes into 512 0 times with a remainder of 512.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 512 leaves us with 512.
Bring next digit (8) of the dividend behind the 512 and repeat the process: 5128 / 627

Step 4:
5128 divided by 627 is 8 with a remainder of 112.
Write down 8 as next digit of the result. 
Result so far: 8.0
The remainder is 112 after subtracting 5016 from 5128.
Append the next digit (9) from the dividend to 112 and continue with: 1129 / 627

On to step 5:
627 can be fit into 1129 1 times, resulting in a remainder of 502.
Write down 1 as next digit of the result. 
Result so far: 81.0
The remainder is 502 after subtracting 627 from 1129.
Fetch the next digit (1) from the dividend, attach it to 502 and continue: 5021 / 627

Step 6:
The number 627 fits into 5021 8 times, leaving a remainder of 5.
Put 8 as the next digit of the answer. 
Result so far: 818.0
If we subtract 5016 from 5021, we get 5.
Grab the next digit (3) from the dividend, add it to 5, then carry on: 53 / 627

Going ahead to step 7:
627 goes into 53 0 times with a remainder of 53.
Use 0 as the next digit of our solution. 
Result so far: 8180.0
Subtract 0 from 53 to get 53.
Include the next digit (6) from the dividend after 53, then repeat: 536 / 627

Let's proceed to step 8:
The number 627 fits into 536 0 times, leaving a remainder of 536.
Record the quotient 0 as the next digit in the result. 
Result so far: 81800.0
Deduct 0 from 536 and we're left with 536.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5360, and continue the process.

Step 9:
The number 627 fits into 5360 8 times, leaving a remainder of 344.
Record the quotient 8 as the next digit in the result. 
Result so far: 81800.8
If we subtract 5016 from 5360, we get 344.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3440, and continue the process.

Advancing to step 10:
627 can be fit into 3440 5 times, resulting in a remainder of 305.
Use 5 as the next digit of our solution. 
Result so far: 81800.85
Deduct 3135 from 3440 and we're left with 305.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3050, and continue the process.

Step 11:
3050 divided by 627 is 4 with a remainder of 542.
Record the quotient 4 as the next digit in the result. 
Result so far: 81800.854
If we subtract 2508 from 3050, we get 542.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5420, and continue the process.

Moving on to step 12:
When dividing 5420 by 627, we get 8 with a remainder of 404.
Record the quotient 8 as the next digit in the result. 
Result so far: 81800.8548
If we take 5016 away from 5420, we end up with 404.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4040, and continue the process.

Let's proceed to step 13:
627 goes into 4040 6 times with a remainder of 278.
Write down 6 as next digit of the result. 
Result so far: 81800.85486
Deduct 3762 from 4040 and we're left with 278.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2780, and continue the process.

Going ahead to step 14:
When dividing 2780 by 627, we get 4 with a remainder of 272.
Record the quotient 4 as the next digit in the result. 
Result so far: 81800.854864
Subtract 2508 from 2780 to get 272.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

On to step 15:
If we divide 2720 by 627, we get 4 and a remainder of 212.
Write down 4 as next digit of the result. 
Result so far: 81800.8548644
If we take 2508 away from 2720, we end up with 212.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

The final result is 81800.8548644 with a remainder of 2.12e-06.
