613944 ÷ 31 
We want to figure out the number of times 613944 can be divided by 31.

Step 1:
6 divided by 31 is 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
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 / 31

Step 2:
31 can be fit into 61 1 times, resulting in a remainder of 30.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 31 from 61 and we're left with 30.
Append the next digit (3) from the dividend to 30 and continue with: 303 / 31

On to step 3:
If we divide 303 by 31, we get 9 and a remainder of 24.
Record the quotient 9 as the next digit in the result. 
Result so far: 19.0
Subtract 279 from 303 to get 24.
Include the next digit (9) from the dividend after 24, then repeat: 249 / 31

On to step 4:
249 divided by 31 is 8 with a remainder of 1.
Record the quotient 8 as the next digit in the result. 
Result so far: 198.0
If we subtract 248 from 249, we get 1.
Append the next digit (4) from the dividend to 1 and continue with: 14 / 31

Moving on to step 5:
14 divided by 31 is 0 with a remainder of 14.
The next digit of our result is 0. 
Result so far: 1980.0
If we take 0 away from 14, we end up with 14.
Take the next digit (4) from the dividend and append it to 14, then repeat: 144 / 31

Step 6:
When dividing 144 by 31, we get 4 with a remainder of 20.
Put 4 as the next digit of the answer. 
Result so far: 19804.0
Deduct 124 from 144 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 7:
If we divide 200 by 31, we get 6 and a remainder of 14.
Use 6 as the next digit of our solution. 
Result so far: 19804.6
The remainder is 14 after subtracting 186 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 8:
If we divide 140 by 31, we get 4 and a remainder of 16.
The number 4 becomes the next digit in our result. 
Result so far: 19804.64
Subtracting 124 from 140 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 9:
The number 31 fits into 160 5 times, leaving a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 19804.645
Deduct 155 from 160 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.

Moving on to step 10:
If we divide 50 by 31, we get 1 and a remainder of 19.
Record the quotient 1 as the next digit in the result. 
Result so far: 19804.6451
Subtract 31 from 50 to get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Going ahead to step 11:
31 goes into 190 6 times with a remainder of 4.
The next digit of our result is 6. 
Result so far: 19804.64516
If we take 186 away from 190, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 12:
40 divided by 31 is 1 with a remainder of 9.
Use 1 as the next digit of our solution. 
Result so far: 19804.645161
If we take 31 away from 40, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 13:
90 divided by 31 is 2 with a remainder of 28.
Record the quotient 2 as the next digit in the result. 
Result so far: 19804.6451612
If we subtract 62 from 90, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 14:
The number 31 fits into 280 9 times, leaving a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 19804.64516129
Subtract 279 from 280 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

The final outcome is 19804.64516129, with a leftover of 1e-09.
