We're dividing 51091597 by 629 
Our goal is to divide 51091597 by 629.

Step 1:
The number 629 fits into 5 0 times, leaving a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Append the next digit (1) from the dividend to 5 and continue with: 51 / 629

On to step 2:
When dividing 51 by 629, we get 0 with a remainder of 51.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 51, we get 51.
Include the next digit (0) from the dividend after 51, then repeat: 510 / 629

Going ahead to step 3:
If we divide 510 by 629, we get 0 and a remainder of 510.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 510 to get 510.
Fetch the next digit (9) from the dividend, attach it to 510 and continue: 5109 / 629

Let's proceed to step 4:
5109 divided by 629 is 8 with a remainder of 77.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Subtracting 5032 from 5109 leaves us with 77.
Bring next digit (1) of the dividend behind the 77 and repeat the process: 771 / 629

Step 5:
When dividing 771 by 629, we get 1 with a remainder of 142.
Use 1 as the next digit of our solution. 
Result so far: 81.0
Deduct 629 from 771 and we're left with 142.
Grab the next digit (5) from the dividend, add it to 142, then carry on: 1425 / 629

Step 6:
When dividing 1425 by 629, we get 2 with a remainder of 167.
The number 2 becomes the next digit in our result. 
Result so far: 812.0
Subtracting 1258 from 1425 leaves us with 167.
Bring next digit (9) of the dividend behind the 167 and repeat the process: 1679 / 629

Advancing to step 7:
If we divide 1679 by 629, we get 2 and a remainder of 421.
Use 2 as the next digit of our solution. 
Result so far: 8122.0
If we subtract 1258 from 1679, we get 421.
Grab the next digit (7) from the dividend, add it to 421, then carry on: 4217 / 629

Let's proceed to step 8:
4217 divided by 629 is 6 with a remainder of 443.
Put 6 as the next digit of the answer. 
Result so far: 81226.0
Subtract 3774 from 4217 to get 443.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4430, and continue the process.

Let's proceed to step 9:
629 goes into 4430 7 times with a remainder of 27.
Record the quotient 7 as the next digit in the result. 
Result so far: 81226.7
If we take 4403 away from 4430, we end up with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Step 10:
The number 629 fits into 270 0 times, leaving a remainder of 270.
Record the quotient 0 as the next digit in the result. 
Result so far: 81226.7
The remainder is 270 after subtracting 0 from 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Step 11:
629 goes into 2700 4 times with a remainder of 184.
Use 4 as the next digit of our solution. 
Result so far: 81226.704
Deduct 2516 from 2700 and we're left with 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Moving on to step 12:
The number 629 fits into 1840 2 times, leaving a remainder of 582.
Put 2 as the next digit of the answer. 
Result so far: 81226.7042
The remainder is 582 after subtracting 1258 from 1840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5820, and continue the process.

On to step 13:
The number 629 fits into 5820 9 times, leaving a remainder of 159.
The number 9 becomes the next digit in our result. 
Result so far: 81226.70429
If we take 5661 away from 5820, we end up with 159.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1590, and continue the process.

Step 14:
629 can be fit into 1590 2 times, resulting in a remainder of 332.
Put 2 as the next digit of the answer. 
Result so far: 81226.704292
If we subtract 1258 from 1590, we get 332.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3320, and continue the process.

Going ahead to step 15:
629 can be fit into 3320 5 times, resulting in a remainder of 175.
Write down 5 as next digit of the result. 
Result so far: 81226.7042925
The remainder is 175 after subtracting 3145 from 3320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

Let's proceed to step 16:
629 goes into 1750 2 times with a remainder of 492.
The next digit of our result is 2. 
Result so far: 81226.70429252
If we subtract 1258 from 1750, we get 492.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4920, and continue the process.

In conclusion, the division gives 81226.70429252 with a balance of 4.92e-07.
