77241095 divided by 20 
We want to figure out the number of times 77241095 can be divided by 20.

Advancing to step 1:
The number 20 fits into 7 0 times, leaving a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Grab the next digit (7) from the dividend, add it to 7, then carry on: 77 / 20

Advancing to step 2:
77 divided by 20 is 3 with a remainder of 17.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Deduct 60 from 77 and we're left with 17.
Bring next digit (2) of the dividend behind the 17 and repeat the process: 172 / 20

Going ahead to step 3:
20 can be fit into 172 8 times, resulting in a remainder of 12.
Use 8 as the next digit of our solution. 
Result so far: 38.0
The remainder is 12 after subtracting 160 from 172.
Fetch the next digit (4) from the dividend, attach it to 12 and continue: 124 / 20

Going ahead to step 4:
When dividing 124 by 20, we get 6 with a remainder of 4.
Use 6 as the next digit of our solution. 
Result so far: 386.0
Deduct 120 from 124 and we're left with 4.
Include the next digit (1) from the dividend after 4, then repeat: 41 / 20

Going ahead to step 5:
41 divided by 20 is 2 with a remainder of 1.
Write down 2 as next digit of the result. 
Result so far: 3862.0
Subtracting 40 from 41 leaves us with 1.
Bring next digit (0) of the dividend behind the 1 and repeat the process: 10 / 20

Step 6:
10 divided by 20 is 0 with a remainder of 10.
The next digit of our result is 0. 
Result so far: 38620.0
Subtract 0 from 10 to get 10.
Fetch the next digit (9) from the dividend, attach it to 10 and continue: 109 / 20

On to step 7:
When dividing 109 by 20, we get 5 with a remainder of 9.
Put 5 as the next digit of the answer. 
Result so far: 386205.0
If we take 100 away from 109, we end up with 9.
Bring next digit (5) of the dividend behind the 9 and repeat the process: 95 / 20

On to step 8:
20 can be fit into 95 4 times, resulting in a remainder of 15.
The number 4 becomes the next digit in our result. 
Result so far: 3862054.0
Subtract 80 from 95 to get 15.
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 9:
150 divided by 20 is 7 with a remainder of 10.
Record the quotient 7 as the next digit in the result. 
Result so far: 3862054.7
Subtract 140 from 150 to 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:
If we divide 100 by 20, we get 5 and a remainder of 0.
The next digit of our result is 5. 
Result so far: 3862054.75
Subtracting 100 from 100 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 11:
20 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 3862054.75
If we subtract 0 from 0, 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.

Advancing to step 12:
The number 20 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 3862054.75
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.

After the division, we end up with 3862054.75 and a remainder of 0.0.
