Let's divide 77483775 by 20
Let's see how many times 20 fits into 77483775.

Moving on to step 1:
7 divided by 20 is 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Take the next digit (7) from the dividend and append it to 7, then repeat: 77 / 20

On to step 2:
If we divide 77 by 20, we get 3 and a remainder of 17.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtracting 60 from 77 leaves us with 17.
Take the next digit (4) from the dividend and append it to 17, then repeat: 174 / 20

Advancing to step 3:
The number 20 fits into 174 8 times, leaving a remainder of 14.
The number 8 becomes the next digit in our result. 
Result so far: 38.0
The remainder is 14 after subtracting 160 from 174.
Fetch the next digit (8) from the dividend, attach it to 14 and continue: 148 / 20

Step 4:
148 divided by 20 is 7 with a remainder of 8.
The next digit of our result is 7. 
Result so far: 387.0
The remainder is 8 after subtracting 140 from 148.
Grab the next digit (3) from the dividend, add it to 8, then carry on: 83 / 20

Let's proceed to step 5:
The number 20 fits into 83 4 times, leaving a remainder of 3.
Record the quotient 4 as the next digit in the result. 
Result so far: 3874.0
If we subtract 80 from 83, we get 3.
Take the next digit (7) from the dividend and append it to 3, then repeat: 37 / 20

On to step 6:
20 goes into 37 1 times with a remainder of 17.
Write down 1 as next digit of the result. 
Result so far: 38741.0
If we subtract 20 from 37, we get 17.
Fetch the next digit (7) from the dividend, attach it to 17 and continue: 177 / 20

Advancing to step 7:
177 divided by 20 is 8 with a remainder of 17.
Use 8 as the next digit of our solution. 
Result so far: 387418.0
If we take 160 away from 177, we end up with 17.
Take the next digit (5) from the dividend and append it to 17, then repeat: 175 / 20

On to step 8:
The number 20 fits into 175 8 times, leaving a remainder of 15.
Use 8 as the next digit of our solution. 
Result so far: 3874188.0
Subtracting 160 from 175 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 9:
150 divided by 20 is 7 with a remainder of 10.
The next digit of our result is 7. 
Result so far: 3874188.7
If we subtract 140 from 150, 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.

On to step 10:
100 divided by 20 is 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 3874188.75
If we take 100 away from 100, we end up 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.

Advancing to step 11:
When dividing 0 by 20, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 3874188.75
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.

Step 12:
0 divided by 20 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 3874188.75
If we take 0 away from 0, we end up 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 3874188.75, with a leftover of 0.0.
