89948621 divided by 20 
We're looking to find how many times 20 goes into 89948621.

Let's proceed to step 1:
If we divide 8 by 20, we get 0 and a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Bring next digit (9) of the dividend behind the 8 and repeat the process: 89 / 20

Advancing to step 2:
89 divided by 20 is 4 with a remainder of 9.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
The remainder is 9 after subtracting 80 from 89.
Fetch the next digit (9) from the dividend, attach it to 9 and continue: 99 / 20

Going ahead to step 3:
99 divided by 20 is 4 with a remainder of 19.
Put 4 as the next digit of the answer. 
Result so far: 44.0
Subtract 80 from 99 to get 19.
Fetch the next digit (4) from the dividend, attach it to 19 and continue: 194 / 20

On to step 4:
20 goes into 194 9 times with a remainder of 14.
Use 9 as the next digit of our solution. 
Result so far: 449.0
The remainder is 14 after subtracting 180 from 194.
Fetch the next digit (8) from the dividend, attach it to 14 and continue: 148 / 20

Advancing to step 5:
20 goes into 148 7 times with a remainder of 8.
The next digit of our result is 7. 
Result so far: 4497.0
If we subtract 140 from 148, we get 8.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 20

Let's proceed to step 6:
86 divided by 20 is 4 with a remainder of 6.
The number 4 becomes the next digit in our result. 
Result so far: 44974.0
Subtract 80 from 86 to get 6.
Include the next digit (2) from the dividend after 6, then repeat: 62 / 20

Let's proceed to step 7:
20 goes into 62 3 times with a remainder of 2.
Write down 3 as next digit of the result. 
Result so far: 449743.0
Deduct 60 from 62 and we're left with 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 20

Advancing to step 8:
If we divide 21 by 20, we get 1 and a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 4497431.0
If we take 20 away from 21, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 9:
When dividing 10 by 20, we get 0 with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 4497431.0
Deduct 0 from 10 and we're left with 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:
The number 20 fits into 100 5 times, leaving a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 4497431.05
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.

On to step 11:
The number 20 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 4497431.05
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.

Advancing to step 12:
If we divide 0 by 20, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 4497431.05
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.

Our division results in 4497431.05 with a remaining 0.0.
