We divide 351631 by 51
We're looking to find how many times 51 goes into 351631.

Step 1:
3 divided by 51 is 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Include the next digit (5) from the dividend after 3, then repeat: 35 / 51

Let's proceed to step 2:
When dividing 35 by 51, we get 0 with a remainder of 35.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 35 and we're left with 35.
Take the next digit (1) from the dividend and append it to 35, then repeat: 351 / 51

Going ahead to step 3:
51 can be fit into 351 6 times, resulting in a remainder of 45.
Put 6 as the next digit of the answer. 
Result so far: 6.0
Subtract 306 from 351 to get 45.
Append the next digit (6) from the dividend to 45 and continue with: 456 / 51

Let's proceed to step 4:
456 divided by 51 is 8 with a remainder of 48.
Put 8 as the next digit of the answer. 
Result so far: 68.0
Deduct 408 from 456 and we're left with 48.
Fetch the next digit (3) from the dividend, attach it to 48 and continue: 483 / 51

Step 5:
51 can be fit into 483 9 times, resulting in a remainder of 24.
Use 9 as the next digit of our solution. 
Result so far: 689.0
If we subtract 459 from 483, we get 24.
Include the next digit (1) from the dividend after 24, then repeat: 241 / 51

On to step 6:
241 divided by 51 is 4 with a remainder of 37.
Put 4 as the next digit of the answer. 
Result so far: 6894.0
The remainder is 37 after subtracting 204 from 241.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

On to step 7:
The number 51 fits into 370 7 times, leaving a remainder of 13.
The next digit of our result is 7. 
Result so far: 6894.7
Subtract 357 from 370 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

On to step 8:
If we divide 130 by 51, we get 2 and a remainder of 28.
Write down 2 as next digit of the result. 
Result so far: 6894.72
The remainder is 28 after subtracting 102 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 9:
The number 51 fits into 280 5 times, leaving a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 6894.725
The remainder is 25 after subtracting 255 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Step 10:
The number 51 fits into 250 4 times, leaving a remainder of 46.
The number 4 becomes the next digit in our result. 
Result so far: 6894.7254
Deduct 204 from 250 and we're left with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Let's proceed to step 11:
The number 51 fits into 460 9 times, leaving a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 6894.72549
Deduct 459 from 460 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 12:
The number 51 fits into 10 0 times, leaving a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 6894.72549
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 13:
100 divided by 51 is 1 with a remainder of 49.
The next digit of our result is 1. 
Result so far: 6894.7254901
The remainder is 49 after subtracting 51 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Step 14:
51 goes into 490 9 times with a remainder of 31.
The next digit of our result is 9. 
Result so far: 6894.72549019
If we subtract 459 from 490, we get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Our division results in 6894.72549019 with a remaining 3.1e-08.
