59781731 ÷ 20 
Our goal is to divide 59781731 by 20.

Moving on to step 1:
The number 20 fits into 5 0 times, leaving a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Grab the next digit (9) from the dividend, add it to 5, then carry on: 59 / 20

Moving on to step 2:
59 divided by 20 is 2 with a remainder of 19.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtract 40 from 59 to get 19.
Include the next digit (7) from the dividend after 19, then repeat: 197 / 20

Going ahead to step 3:
The number 20 fits into 197 9 times, leaving a remainder of 17.
Record the quotient 9 as the next digit in the result. 
Result so far: 29.0
If we subtract 180 from 197, we get 17.
Grab the next digit (8) from the dividend, add it to 17, then carry on: 178 / 20

Advancing to step 4:
The number 20 fits into 178 8 times, leaving a remainder of 18.
The next digit of our result is 8. 
Result so far: 298.0
If we take 160 away from 178, we end up with 18.
Grab the next digit (1) from the dividend, add it to 18, then carry on: 181 / 20

Step 5:
20 can be fit into 181 9 times, resulting in a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 2989.0
The remainder is 1 after subtracting 180 from 181.
Take the next digit (7) from the dividend and append it to 1, then repeat: 17 / 20

On to step 6:
20 can be fit into 17 0 times, resulting in a remainder of 17.
The number 0 becomes the next digit in our result. 
Result so far: 29890.0
The remainder is 17 after subtracting 0 from 17.
Take the next digit (3) from the dividend and append it to 17, then repeat: 173 / 20

Moving on to step 7:
The number 20 fits into 173 8 times, leaving a remainder of 13.
The number 8 becomes the next digit in our result. 
Result so far: 298908.0
The remainder is 13 after subtracting 160 from 173.
Grab the next digit (1) from the dividend, add it to 13, then carry on: 131 / 20

On to step 8:
20 can be fit into 131 6 times, resulting in a remainder of 11.
Use 6 as the next digit of our solution. 
Result so far: 2989086.0
Deduct 120 from 131 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 9:
20 can be fit into 110 5 times, resulting in a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 2989086.5
The remainder is 10 after subtracting 100 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 10:
If we divide 100 by 20, we get 5 and a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 2989086.55
Subtract 100 from 100 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.

The final result is 2989086.55 with a remainder of 0.0.
