31778218 ÷ 20 
We want to divide 31778218 by 20.

Advancing to step 1:
20 goes into 3 0 times with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Grab the next digit (1) from the dividend, add it to 3, then carry on: 31 / 20

Advancing to step 2:
20 can be fit into 31 1 times, resulting in a remainder of 11.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 20 from 31 to get 11.
Append the next digit (7) from the dividend to 11 and continue with: 117 / 20

Step 3:
When dividing 117 by 20, we get 5 with a remainder of 17.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
If we subtract 100 from 117, we get 17.
Fetch the next digit (7) from the dividend, attach it to 17 and continue: 177 / 20

Step 4:
177 divided by 20 is 8 with a remainder of 17.
Record the quotient 8 as the next digit in the result. 
Result so far: 158.0
If we subtract 160 from 177, we get 17.
Bring next digit (8) of the dividend behind the 17 and repeat the process: 178 / 20

Step 5:
When dividing 178 by 20, we get 8 with a remainder of 18.
Use 8 as the next digit of our solution. 
Result so far: 1588.0
Subtracting 160 from 178 leaves us with 18.
Include the next digit (2) from the dividend after 18, then repeat: 182 / 20

Going ahead to step 6:
182 divided by 20 is 9 with a remainder of 2.
The next digit of our result is 9. 
Result so far: 15889.0
If we subtract 180 from 182, we get 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 20

On to step 7:
When dividing 21 by 20, we get 1 with a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 158891.0
The remainder is 1 after subtracting 20 from 21.
Bring next digit (8) of the dividend behind the 1 and repeat the process: 18 / 20

Going ahead to step 8:
The number 20 fits into 18 0 times, leaving a remainder of 18.
Use 0 as the next digit of our solution. 
Result so far: 1588910.0
If we take 0 away from 18, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 9:
When dividing 180 by 20, we get 9 with a remainder of 0.
Record the quotient 9 as the next digit in the result. 
Result so far: 1588910.9
If we subtract 180 from 180, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 10:
20 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 1588910.9
Subtract 0 from 0 to get 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 11:
20 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 1588910.9
Deduct 0 from 0 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.

The final outcome is 1588910.9, with a leftover of 0.0.
