We're dividing 87553824 by 20 
Our goal is to divide 87553824 by 20.

Advancing to step 1:
20 goes into 8 0 times with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Include the next digit (7) from the dividend after 8, then repeat: 87 / 20

On to step 2:
87 divided by 20 is 4 with a remainder of 7.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Deduct 80 from 87 and we're left with 7.
Include the next digit (5) from the dividend after 7, then repeat: 75 / 20

Moving on to step 3:
75 divided by 20 is 3 with a remainder of 15.
The next digit of our result is 3. 
Result so far: 43.0
If we take 60 away from 75, we end up with 15.
Take the next digit (5) from the dividend and append it to 15, then repeat: 155 / 20

On to step 4:
155 divided by 20 is 7 with a remainder of 15.
Record the quotient 7 as the next digit in the result. 
Result so far: 437.0
If we subtract 140 from 155, we get 15.
Grab the next digit (3) from the dividend, add it to 15, then carry on: 153 / 20

Moving on to step 5:
20 goes into 153 7 times with a remainder of 13.
Write down 7 as next digit of the result. 
Result so far: 4377.0
Deduct 140 from 153 and we're left with 13.
Take the next digit (8) from the dividend and append it to 13, then repeat: 138 / 20

Advancing to step 6:
20 can be fit into 138 6 times, resulting in a remainder of 18.
The number 6 becomes the next digit in our result. 
Result so far: 43776.0
The remainder is 18 after subtracting 120 from 138.
Grab the next digit (2) from the dividend, add it to 18, then carry on: 182 / 20

Step 7:
If we divide 182 by 20, we get 9 and a remainder of 2.
The number 9 becomes the next digit in our result. 
Result so far: 437769.0
If we subtract 180 from 182, we get 2.
Fetch the next digit (4) from the dividend, attach it to 2 and continue: 24 / 20

Step 8:
The number 20 fits into 24 1 times, leaving a remainder of 4.
Use 1 as the next digit of our solution. 
Result so far: 4377691.0
Subtracting 20 from 24 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 9:
40 divided by 20 is 2 with a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 4377691.2
If we subtract 40 from 40, 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.

Going ahead to step 10:
20 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 4377691.2
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 11:
20 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 4377691.2
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.

After the division, we end up with 4377691.2 and a remainder of 0.0.
