375221 divided by 51 
Let's see how many times 51 fits into 375221.

Let's proceed to step 1:
If we divide 3 by 51, we get 0 and a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Take the next digit (7) from the dividend and append it to 3, then repeat: 37 / 51

Advancing to step 2:
51 goes into 37 0 times with a remainder of 37.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 37 leaves us with 37.
Include the next digit (5) from the dividend after 37, then repeat: 375 / 51

On to step 3:
If we divide 375 by 51, we get 7 and a remainder of 18.
Write down 7 as next digit of the result. 
Result so far: 7.0
Subtract 357 from 375 to get 18.
Append the next digit (2) from the dividend to 18 and continue with: 182 / 51

On to step 4:
182 divided by 51 is 3 with a remainder of 29.
Write down 3 as next digit of the result. 
Result so far: 73.0
Subtract 153 from 182 to get 29.
Bring next digit (2) of the dividend behind the 29 and repeat the process: 292 / 51

Going ahead to step 5:
292 divided by 51 is 5 with a remainder of 37.
Record the quotient 5 as the next digit in the result. 
Result so far: 735.0
If we take 255 away from 292, we end up with 37.
Fetch the next digit (1) from the dividend, attach it to 37 and continue: 371 / 51

Going ahead to step 6:
371 divided by 51 is 7 with a remainder of 14.
The next digit of our result is 7. 
Result so far: 7357.0
The remainder is 14 after subtracting 357 from 371.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 7:
140 divided by 51 is 2 with a remainder of 38.
Use 2 as the next digit of our solution. 
Result so far: 7357.2
Subtracting 102 from 140 leaves us 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.

On to step 8:
380 divided by 51 is 7 with a remainder of 23.
Put 7 as the next digit of the answer. 
Result so far: 7357.27
The remainder is 23 after subtracting 357 from 380.
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 9:
51 can be fit into 230 4 times, resulting in a remainder of 26.
The number 4 becomes the next digit in our result. 
Result so far: 7357.274
Subtracting 204 from 230 leaves us with 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 10:
51 can be fit into 260 5 times, resulting in a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 7357.2745
Subtracting 255 from 260 leaves us 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.

Going ahead to step 11:
51 can be fit into 50 0 times, resulting in a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 7357.2745
If we take 0 away from 50, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 12:
If we divide 500 by 51, we get 9 and a remainder of 41.
Put 9 as the next digit of the answer. 
Result so far: 7357.274509
Subtracting 459 from 500 leaves us with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Going ahead to step 13:
If we divide 410 by 51, we get 8 and a remainder of 2.
Write down 8 as next digit of the result. 
Result so far: 7357.2745098
If we take 408 away from 410, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 14:
20 divided by 51 is 0 with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 7357.2745098
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The final outcome is 7357.2745098, with a leftover of 2e-08.
