403637 ÷ 51 
Our goal is to divide 403637 by 51.

Let's proceed to step 1:
When dividing 4 by 51, we get 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Include the next digit (0) from the dividend after 4, then repeat: 40 / 51

Step 2:
If we divide 40 by 51, we get 0 and a remainder of 40.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 40, we get 40.
Append the next digit (3) from the dividend to 40 and continue with: 403 / 51

On to step 3:
If we divide 403 by 51, we get 7 and a remainder of 46.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Subtracting 357 from 403 leaves us with 46.
Fetch the next digit (6) from the dividend, attach it to 46 and continue: 466 / 51

Let's proceed to step 4:
When dividing 466 by 51, we get 9 with a remainder of 7.
The next digit of our result is 9. 
Result so far: 79.0
Subtract 459 from 466 to get 7.
Grab the next digit (3) from the dividend, add it to 7, then carry on: 73 / 51

Let's proceed to step 5:
51 goes into 73 1 times with a remainder of 22.
The number 1 becomes the next digit in our result. 
Result so far: 791.0
Subtracting 51 from 73 leaves us with 22.
Take the next digit (7) from the dividend and append it to 22, then repeat: 227 / 51

Let's proceed to step 6:
When dividing 227 by 51, we get 4 with a remainder of 23.
Use 4 as the next digit of our solution. 
Result so far: 7914.0
Subtract 204 from 227 to 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.

Let's proceed to step 7:
230 divided by 51 is 4 with a remainder of 26.
Record the quotient 4 as the next digit in the result. 
Result so far: 7914.4
If we take 204 away from 230, we end up 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.

Moving on to step 8:
The number 51 fits into 260 5 times, leaving a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 7914.45
Deduct 255 from 260 and we're left 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 9:
When dividing 50 by 51, we get 0 with a remainder of 50.
Put 0 as the next digit of the answer. 
Result so far: 7914.45
The remainder is 50 after subtracting 0 from 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 10:
The number 51 fits into 500 9 times, leaving a remainder of 41.
The number 9 becomes the next digit in our result. 
Result so far: 7914.4509
The remainder is 41 after subtracting 459 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Moving on to step 11:
410 divided by 51 is 8 with a remainder of 2.
Put 8 as the next digit of the answer. 
Result so far: 7914.45098
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.

Let's proceed to step 12:
If we divide 20 by 51, we get 0 and a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 7914.45098
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 13:
If we divide 200 by 51, we get 3 and a remainder of 47.
The number 3 becomes the next digit in our result. 
Result so far: 7914.4509803
Subtracting 153 from 200 leaves us with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Moving on to step 14:
The number 51 fits into 470 9 times, leaving a remainder of 11.
Write down 9 as next digit of the result. 
Result so far: 7914.45098039
The remainder is 11 after subtracting 459 from 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

The final outcome is 7914.45098039, with a leftover of 1.1e-08.
