We look at the division of 622900 by 31 
We want to figure out the number of times 622900 can be divided by 31.

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
Deduct 0 from 6 and we're left with 6.
Append the next digit (2) from the dividend to 6 and continue with: 62 / 31

Going ahead to step 2:
62 divided by 31 is 2 with a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we take 62 away from 62, we end up with 0.
Grab the next digit (2) from the dividend, add it to 0, then carry on: 2 / 31

On to step 3:
The number 31 fits into 2 0 times, leaving a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 20.0
The remainder is 2 after subtracting 0 from 2.
Fetch the next digit (9) from the dividend, attach it to 2 and continue: 29 / 31

On to step 4:
31 can be fit into 29 0 times, resulting in a remainder of 29.
Record the quotient 0 as the next digit in the result. 
Result so far: 200.0
Subtracting 0 from 29 leaves us with 29.
Take the next digit (0) from the dividend and append it to 29, then repeat: 290 / 31

Let's proceed to step 5:
If we divide 290 by 31, we get 9 and a remainder of 11.
Record the quotient 9 as the next digit in the result. 
Result so far: 2009.0
Deduct 279 from 290 and we're left with 11.
Fetch the next digit (0) from the dividend, attach it to 11 and continue: 110 / 31

On to step 6:
The number 31 fits into 110 3 times, leaving a remainder of 17.
The next digit of our result is 3. 
Result so far: 20093.0
Subtract 93 from 110 to 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.

Advancing to step 7:
170 divided by 31 is 5 with a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 20093.5
The remainder is 15 after subtracting 155 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 8:
150 divided by 31 is 4 with a remainder of 26.
Write down 4 as next digit of the result. 
Result so far: 20093.54
Deduct 124 from 150 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.

Moving on to step 9:
31 goes into 260 8 times with a remainder of 12.
Write down 8 as next digit of the result. 
Result so far: 20093.548
Subtracting 248 from 260 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 10:
31 goes into 120 3 times with a remainder of 27.
Put 3 as the next digit of the answer. 
Result so far: 20093.5483
Subtract 93 from 120 to 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.

Advancing to step 11:
31 goes into 270 8 times with a remainder of 22.
The number 8 becomes the next digit in our result. 
Result so far: 20093.54838
If we take 248 away from 270, we end up 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.

On to step 12:
The number 31 fits into 220 7 times, leaving a remainder of 3.
Write down 7 as next digit of the result. 
Result so far: 20093.548387
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.

Let's proceed to step 13:
30 divided by 31 is 0 with a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 20093.548387
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.

Advancing to step 14:
31 goes into 300 9 times with a remainder of 21.
Record the quotient 9 as the next digit in the result. 
Result so far: 20093.54838709
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.

The final outcome is 20093.54838709, with a leftover of 2.1e-08.
