We divide 225815 by 51
We want to divide 225815 by 51.

Step 1:
2 divided by 51 is 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Append the next digit (2) from the dividend to 2 and continue with: 22 / 51

Step 2:
51 can be fit into 22 0 times, resulting in a remainder of 22.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 22 leaves us with 22.
Append the next digit (5) from the dividend to 22 and continue with: 225 / 51

Going ahead to step 3:
If we divide 225 by 51, we get 4 and a remainder of 21.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Deduct 204 from 225 and we're left with 21.
Grab the next digit (8) from the dividend, add it to 21, then carry on: 218 / 51

Step 4:
If we divide 218 by 51, we get 4 and a remainder of 14.
Put 4 as the next digit of the answer. 
Result so far: 44.0
Subtracting 204 from 218 leaves us with 14.
Grab the next digit (1) from the dividend, add it to 14, then carry on: 141 / 51

Moving on to step 5:
If we divide 141 by 51, we get 2 and a remainder of 39.
Put 2 as the next digit of the answer. 
Result so far: 442.0
Deduct 102 from 141 and we're left with 39.
Fetch the next digit (5) from the dividend, attach it to 39 and continue: 395 / 51

Let's proceed to step 6:
51 goes into 395 7 times with a remainder of 38.
Use 7 as the next digit of our solution. 
Result so far: 4427.0
Subtracting 357 from 395 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.

Let's proceed to step 7:
51 goes into 380 7 times with a remainder of 23.
Put 7 as the next digit of the answer. 
Result so far: 4427.7
Subtracting 357 from 380 leaves us with 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 8:
If we divide 230 by 51, we get 4 and a remainder of 26.
Write down 4 as next digit of the result. 
Result so far: 4427.74
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.

On to step 9:
When dividing 260 by 51, we get 5 with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 4427.745
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.

Moving on to step 10:
If we divide 50 by 51, we get 0 and a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 4427.745
Subtracting 0 from 50 leaves us 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.

Advancing to step 11:
51 goes into 500 9 times with a remainder of 41.
The number 9 becomes the next digit in our result. 
Result so far: 4427.74509
Deduct 459 from 500 and we're left 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.

Let's proceed to step 12:
When dividing 410 by 51, we get 8 with a remainder of 2.
The next digit of our result is 8. 
Result so far: 4427.745098
If we subtract 408 from 410, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 13:
The number 51 fits into 20 0 times, leaving a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 4427.745098
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 14:
If we divide 200 by 51, we get 3 and a remainder of 47.
Write down 3 as next digit of the result. 
Result so far: 4427.74509803
If we subtract 153 from 200, we get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Our division results in 4427.74509803 with a remaining 4.7e-08.
