619986 ÷ 31 
We're looking to find how many times 31 goes into 619986.

Advancing to step 1:
6 divided by 31 is 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Take the next digit (1) from the dividend and append it to 6, then repeat: 61 / 31

On to step 2:
The number 31 fits into 61 1 times, leaving a remainder of 30.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 31 from 61 and we're left with 30.
Take the next digit (9) from the dividend and append it to 30, then repeat: 309 / 31

Going ahead to step 3:
31 goes into 309 9 times with a remainder of 30.
Use 9 as the next digit of our solution. 
Result so far: 19.0
Subtract 279 from 309 to get 30.
Take the next digit (9) from the dividend and append it to 30, then repeat: 309 / 31

Advancing to step 4:
The number 31 fits into 309 9 times, leaving a remainder of 30.
Put 9 as the next digit of the answer. 
Result so far: 199.0
Deduct 279 from 309 and we're left with 30.
Include the next digit (8) from the dividend after 30, then repeat: 308 / 31

Step 5:
31 goes into 308 9 times with a remainder of 29.
Record the quotient 9 as the next digit in the result. 
Result so far: 1999.0
Subtract 279 from 308 to get 29.
Bring next digit (6) of the dividend behind the 29 and repeat the process: 296 / 31

On to step 6:
31 can be fit into 296 9 times, resulting in a remainder of 17.
Put 9 as the next digit of the answer. 
Result so far: 19999.0
If we subtract 279 from 296, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Let's proceed to step 7:
When dividing 170 by 31, we get 5 with a remainder of 15.
The next digit of our result is 5. 
Result so far: 19999.5
If we subtract 155 from 170, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 8:
150 divided by 31 is 4 with a remainder of 26.
The next digit of our result is 4. 
Result so far: 19999.54
If we take 124 away from 150, 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.

Going ahead to step 9:
If we divide 260 by 31, we get 8 and a remainder of 12.
The next digit of our result is 8. 
Result so far: 19999.548
Subtract 248 from 260 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 10:
120 divided by 31 is 3 with a remainder of 27.
Record the quotient 3 as the next digit in the result. 
Result so far: 19999.5483
If we subtract 93 from 120, we get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Step 11:
When dividing 270 by 31, we get 8 with a remainder of 22.
Write down 8 as next digit of the result. 
Result so far: 19999.54838
If we subtract 248 from 270, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 12:
220 divided by 31 is 7 with a remainder of 3.
Use 7 as the next digit of our solution. 
Result so far: 19999.548387
If we take 217 away from 220, we end up 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.

On to step 13:
The number 31 fits into 30 0 times, leaving a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 19999.548387
If we take 0 away from 30, we end up 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.

Let's proceed to step 14:
When dividing 300 by 31, we get 9 with a remainder of 21.
Put 9 as the next digit of the answer. 
Result so far: 19999.54838709
Subtracting 279 from 300 leaves us 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.

The final result is 19999.54838709 with a remainder of 2.1e-08.
