Let's divide 357856 by 51
We're looking to find how many times 51 goes into 357856.

Step 1:
When dividing 3 by 51, we get 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Grab the next digit (5) from the dividend, add it to 3, then carry on: 35 / 51

Going ahead to step 2:
If we divide 35 by 51, we get 0 and a remainder of 35.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 35, we end up with 35.
Include the next digit (7) from the dividend after 35, then repeat: 357 / 51

Step 3:
The number 51 fits into 357 7 times, leaving a remainder of 0.
The next digit of our result is 7. 
Result so far: 7.0
If we take 357 away from 357, we end up with 0.
Bring next digit (8) of the dividend behind the 0 and repeat the process: 8 / 51

Advancing to step 4:
51 can be fit into 8 0 times, resulting in a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 70.0
Subtracting 0 from 8 leaves us with 8.
Bring next digit (5) of the dividend behind the 8 and repeat the process: 85 / 51

Moving on to step 5:
51 goes into 85 1 times with a remainder of 34.
Put 1 as the next digit of the answer. 
Result so far: 701.0
Subtracting 51 from 85 leaves us with 34.
Bring next digit (6) of the dividend behind the 34 and repeat the process: 346 / 51

On to step 6:
When dividing 346 by 51, we get 6 with a remainder of 40.
Put 6 as the next digit of the answer. 
Result so far: 7016.0
The remainder is 40 after subtracting 306 from 346.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 7:
The number 51 fits into 400 7 times, leaving a remainder of 43.
Use 7 as the next digit of our solution. 
Result so far: 7016.7
Deduct 357 from 400 and we're left with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

On to step 8:
The number 51 fits into 430 8 times, leaving a remainder of 22.
The number 8 becomes the next digit in our result. 
Result so far: 7016.78
If we subtract 408 from 430, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 9:
220 divided by 51 is 4 with a remainder of 16.
Use 4 as the next digit of our solution. 
Result so far: 7016.784
Subtracting 204 from 220 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 10:
51 goes into 160 3 times with a remainder of 7.
Use 3 as the next digit of our solution. 
Result so far: 7016.7843
Subtracting 153 from 160 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 11:
The number 51 fits into 70 1 times, leaving a remainder of 19.
Put 1 as the next digit of the answer. 
Result so far: 7016.78431
Subtract 51 from 70 to get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

On to step 12:
190 divided by 51 is 3 with a remainder of 37.
Use 3 as the next digit of our solution. 
Result so far: 7016.784313
Subtract 153 from 190 to get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Going ahead to step 13:
The number 51 fits into 370 7 times, leaving a remainder of 13.
Write down 7 as next digit of the result. 
Result so far: 7016.7843137
Deduct 357 from 370 and we're left with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 14:
When dividing 130 by 51, we get 2 with a remainder of 28.
The number 2 becomes the next digit in our result. 
Result so far: 7016.78431372
Subtracting 102 from 130 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

The final result is 7016.78431372 with a remainder of 2.8e-08.
