We look at the division of 610738 by 31 
We want to figure out the number of times 610738 can be divided by 31.

Step 1:
The number 31 fits into 6 0 times, leaving a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Grab the next digit (1) from the dividend, add it to 6, then carry on: 61 / 31

Advancing to step 2:
The number 31 fits into 61 1 times, leaving a remainder of 30.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 31 from 61, we get 30.
Append the next digit (0) from the dividend to 30 and continue with: 300 / 31

Moving on to step 3:
If we divide 300 by 31, we get 9 and a remainder of 21.
Record the quotient 9 as the next digit in the result. 
Result so far: 19.0
Subtracting 279 from 300 leaves us with 21.
Append the next digit (7) from the dividend to 21 and continue with: 217 / 31

Moving on to step 4:
If we divide 217 by 31, we get 7 and a remainder of 0.
Write down 7 as next digit of the result. 
Result so far: 197.0
Deduct 217 from 217 and we're left with 0.
Bring next digit (3) of the dividend behind the 0 and repeat the process: 3 / 31

Moving on to step 5:
When dividing 3 by 31, we get 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 1970.0
Subtracting 0 from 3 leaves us with 3.
Bring next digit (8) of the dividend behind the 3 and repeat the process: 38 / 31

Advancing to step 6:
When dividing 38 by 31, we get 1 with a remainder of 7.
The number 1 becomes the next digit in our result. 
Result so far: 19701.0
Subtracting 31 from 38 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 7:
If we divide 70 by 31, we get 2 and a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 19701.2
If we take 62 away from 70, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 8:
If we divide 80 by 31, we get 2 and a remainder of 18.
Write down 2 as next digit of the result. 
Result so far: 19701.22
The remainder is 18 after subtracting 62 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Our division results in 19701.22 with a remaining 0.018.
