We look at the division of 155570 by 31 
We want to divide 155570 by 31.

Step 1:
31 goes into 1 0 times with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Bring next digit (5) of the dividend behind the 1 and repeat the process: 15 / 31

Moving on to step 2:
31 goes into 15 0 times with a remainder of 15.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 15 to get 15.
Grab the next digit (5) from the dividend, add it to 15, then carry on: 155 / 31

On to step 3:
31 can be fit into 155 5 times, resulting in a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 5.0
If we take 155 away from 155, we end up with 0.
Append the next digit (5) from the dividend to 0 and continue with: 5 / 31

Step 4:
The number 31 fits into 5 0 times, leaving a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 50.0
Subtracting 0 from 5 leaves us with 5.
Append the next digit (7) from the dividend to 5 and continue with: 57 / 31

Let's proceed to step 5:
31 goes into 57 1 times with a remainder of 26.
Record the quotient 1 as the next digit in the result. 
Result so far: 501.0
The remainder is 26 after subtracting 31 from 57.
Bring next digit (0) of the dividend behind the 26 and repeat the process: 260 / 31

Let's proceed to step 6:
31 goes into 260 8 times with a remainder of 12.
The number 8 becomes the next digit in our result. 
Result so far: 5018.0
The remainder is 12 after subtracting 248 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 7:
The number 31 fits into 120 3 times, leaving a remainder of 27.
Write down 3 as next digit of the result. 
Result so far: 5018.3
Subtracting 93 from 120 leaves us with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Moving on to step 8:
The number 31 fits into 270 8 times, leaving a remainder of 22.
The next digit of our result is 8. 
Result so far: 5018.38
Subtracting 248 from 270 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 9:
If we divide 220 by 31, we get 7 and a remainder of 3.
The next digit of our result is 7. 
Result so far: 5018.387
Subtracting 217 from 220 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 10:
When dividing 30 by 31, we get 0 with a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 5018.387
Deduct 0 from 30 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 11:
When dividing 300 by 31, we get 9 with a remainder of 21.
The number 9 becomes the next digit in our result. 
Result so far: 5018.38709
Deduct 279 from 300 and we're left with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Step 12:
The number 31 fits into 210 6 times, leaving a remainder of 24.
The next digit of our result is 6. 
Result so far: 5018.387096
If we subtract 186 from 210, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 13:
If we divide 240 by 31, we get 7 and a remainder of 23.
Put 7 as the next digit of the answer. 
Result so far: 5018.3870967
Subtract 217 from 240 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.

Moving on to step 14:
230 divided by 31 is 7 with a remainder of 13.
The next digit of our result is 7. 
Result so far: 5018.38709677
Deduct 217 from 230 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.

The final outcome is 5018.38709677, with a leftover of 1.3e-08.
