629726 ÷ 51 
We want to divide 629726 by 51.

Moving on to step 1:
51 goes into 6 0 times with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Grab the next digit (2) from the dividend, add it to 6, then carry on: 62 / 51

Let's proceed to step 2:
62 divided by 51 is 1 with a remainder of 11.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 51 from 62 and we're left with 11.
Take the next digit (9) from the dividend and append it to 11, then repeat: 119 / 51

Step 3:
51 can be fit into 119 2 times, resulting in a remainder of 17.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
If we take 102 away from 119, we end up with 17.
Grab the next digit (7) from the dividend, add it to 17, then carry on: 177 / 51

Going ahead to step 4:
177 divided by 51 is 3 with a remainder of 24.
Write down 3 as next digit of the result. 
Result so far: 123.0
If we take 153 away from 177, we end up with 24.
Bring next digit (2) of the dividend behind the 24 and repeat the process: 242 / 51

Advancing to step 5:
When dividing 242 by 51, we get 4 with a remainder of 38.
The number 4 becomes the next digit in our result. 
Result so far: 1234.0
Deduct 204 from 242 and we're left with 38.
Bring next digit (6) of the dividend behind the 38 and repeat the process: 386 / 51

Moving on to step 6:
51 goes into 386 7 times with a remainder of 29.
Put 7 as the next digit of the answer. 
Result so far: 12347.0
Deduct 357 from 386 and we're left with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

On to step 7:
51 can be fit into 290 5 times, resulting in a remainder of 35.
Write down 5 as next digit of the result. 
Result so far: 12347.5
The remainder is 35 after subtracting 255 from 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Moving on to step 8:
51 goes into 350 6 times with a remainder of 44.
Record the quotient 6 as the next digit in the result. 
Result so far: 12347.56
Subtracting 306 from 350 leaves us with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Step 9:
The number 51 fits into 440 8 times, leaving a remainder of 32.
Use 8 as the next digit of our solution. 
Result so far: 12347.568
If we take 408 away from 440, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 10:
If we divide 320 by 51, we get 6 and a remainder of 14.
Record the quotient 6 as the next digit in the result. 
Result so far: 12347.5686
Subtracting 306 from 320 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 11:
When dividing 140 by 51, we get 2 with a remainder of 38.
Record the quotient 2 as the next digit in the result. 
Result so far: 12347.56862
Deduct 102 from 140 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Moving on to step 12:
380 divided by 51 is 7 with a remainder of 23.
Use 7 as the next digit of our solution. 
Result so far: 12347.568627
If we subtract 357 from 380, we get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Going ahead to step 13:
230 divided by 51 is 4 with a remainder of 26.
Write down 4 as next digit of the result. 
Result so far: 12347.5686274
If we subtract 204 from 230, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Going ahead to step 14:
51 goes into 260 5 times with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 12347.56862745
If we take 255 away from 260, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Our division results in 12347.56862745 with a remaining 5e-09.
