31247183 ÷ 20 
We want to figure out the number of times 31247183 can be divided by 20.

Step 1:
20 can be fit into 3 0 times, resulting in a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Bring next digit (1) of the dividend behind the 3 and repeat the process: 31 / 20

Let's proceed to step 2:
20 goes into 31 1 times with a remainder of 11.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 20 from 31, we get 11.
Bring next digit (2) of the dividend behind the 11 and repeat the process: 112 / 20

Advancing to step 3:
20 can be fit into 112 5 times, resulting in a remainder of 12.
Put 5 as the next digit of the answer. 
Result so far: 15.0
Deduct 100 from 112 and we're left with 12.
Append the next digit (4) from the dividend to 12 and continue with: 124 / 20

Advancing to step 4:
20 goes into 124 6 times with a remainder of 4.
Use 6 as the next digit of our solution. 
Result so far: 156.0
Deduct 120 from 124 and we're left with 4.
Grab the next digit (7) from the dividend, add it to 4, then carry on: 47 / 20

On to step 5:
20 goes into 47 2 times with a remainder of 7.
Use 2 as the next digit of our solution. 
Result so far: 1562.0
If we subtract 40 from 47, we get 7.
Fetch the next digit (1) from the dividend, attach it to 7 and continue: 71 / 20

Advancing to step 6:
The number 20 fits into 71 3 times, leaving a remainder of 11.
Record the quotient 3 as the next digit in the result. 
Result so far: 15623.0
If we subtract 60 from 71, we get 11.
Grab the next digit (8) from the dividend, add it to 11, then carry on: 118 / 20

Advancing to step 7:
118 divided by 20 is 5 with a remainder of 18.
Record the quotient 5 as the next digit in the result. 
Result so far: 156235.0
Deduct 100 from 118 and we're left with 18.
Take the next digit (3) from the dividend and append it to 18, then repeat: 183 / 20

Let's proceed to step 8:
The number 20 fits into 183 9 times, leaving a remainder of 3.
Use 9 as the next digit of our solution. 
Result so far: 1562359.0
If we subtract 180 from 183, we get 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 9:
20 can be fit into 30 1 times, resulting in a remainder of 10.
Write down 1 as next digit of the result. 
Result so far: 1562359.1
If we subtract 20 from 30, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 10:
100 divided by 20 is 5 with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 1562359.15
Deduct 100 from 100 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 11:
20 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 1562359.15
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 12:
20 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 1562359.15
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 1562359.15, with a leftover of 0.0.
