615131 ÷ 45 
We want to divide 615131 by 45.

Advancing to step 1:
If we divide 6 by 45, we get 0 and a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Append the next digit (1) from the dividend to 6 and continue with: 61 / 45

Step 2:
61 divided by 45 is 1 with a remainder of 16.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 45 from 61 and we're left with 16.
Bring next digit (5) of the dividend behind the 16 and repeat the process: 165 / 45

Advancing to step 3:
The number 45 fits into 165 3 times, leaving a remainder of 30.
Write down 3 as next digit of the result. 
Result so far: 13.0
Deduct 135 from 165 and we're left with 30.
Append the next digit (1) from the dividend to 30 and continue with: 301 / 45

On to step 4:
45 goes into 301 6 times with a remainder of 31.
Write down 6 as next digit of the result. 
Result so far: 136.0
Subtracting 270 from 301 leaves us with 31.
Grab the next digit (3) from the dividend, add it to 31, then carry on: 313 / 45

Going ahead to step 5:
The number 45 fits into 313 6 times, leaving a remainder of 43.
The number 6 becomes the next digit in our result. 
Result so far: 1366.0
Subtract 270 from 313 to get 43.
Bring next digit (1) of the dividend behind the 43 and repeat the process: 431 / 45

Advancing to step 6:
45 can be fit into 431 9 times, resulting in a remainder of 26.
The next digit of our result is 9. 
Result so far: 13669.0
Deduct 405 from 431 and we're left 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.

Advancing to step 7:
If we divide 260 by 45, we get 5 and a remainder of 35.
The next digit of our result is 5. 
Result so far: 13669.5
If we subtract 225 from 260, we get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

On to step 8:
350 divided by 45 is 7 with a remainder of 35.
Put 7 as the next digit of the answer. 
Result so far: 13669.57
If we take 315 away from 350, we end up with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Moving on to step 9:
If we divide 350 by 45, we get 7 and a remainder of 35.
Record the quotient 7 as the next digit in the result. 
Result so far: 13669.577
The remainder is 35 after subtracting 315 from 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

After the division, we end up with 13669.577 and a remainder of 0.0035.
