Let's divide 89495506 by 21
We want to figure out the number of times 89495506 can be divided by 21.

Moving on to step 1:
When dividing 8 by 21, we get 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Take the next digit (9) from the dividend and append it to 8, then repeat: 89 / 21

Moving on to step 2:
The number 21 fits into 89 4 times, leaving a remainder of 5.
Write down 4 as next digit of the result. 
Result so far: 4.0
The remainder is 5 after subtracting 84 from 89.
Append the next digit (4) from the dividend to 5 and continue with: 54 / 21

Let's proceed to step 3:
54 divided by 21 is 2 with a remainder of 12.
The next digit of our result is 2. 
Result so far: 42.0
Subtracting 42 from 54 leaves us with 12.
Grab the next digit (9) from the dividend, add it to 12, then carry on: 129 / 21

Going ahead to step 4:
If we divide 129 by 21, we get 6 and a remainder of 3.
Put 6 as the next digit of the answer. 
Result so far: 426.0
Subtracting 126 from 129 leaves us with 3.
Include the next digit (5) from the dividend after 3, then repeat: 35 / 21

Going ahead to step 5:
When dividing 35 by 21, we get 1 with a remainder of 14.
The number 1 becomes the next digit in our result. 
Result so far: 4261.0
If we subtract 21 from 35, we get 14.
Grab the next digit (5) from the dividend, add it to 14, then carry on: 145 / 21

Let's proceed to step 6:
21 can be fit into 145 6 times, resulting in a remainder of 19.
Record the quotient 6 as the next digit in the result. 
Result so far: 42616.0
The remainder is 19 after subtracting 126 from 145.
Include the next digit (0) from the dividend after 19, then repeat: 190 / 21

Advancing to step 7:
If we divide 190 by 21, we get 9 and a remainder of 1.
Put 9 as the next digit of the answer. 
Result so far: 426169.0
If we take 189 away from 190, we end up with 1.
Include the next digit (6) from the dividend after 1, then repeat: 16 / 21

Advancing to step 8:
The number 21 fits into 16 0 times, leaving a remainder of 16.
Put 0 as the next digit of the answer. 
Result so far: 4261690.0
If we subtract 0 from 16, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 9:
When dividing 160 by 21, we get 7 with a remainder of 13.
Put 7 as the next digit of the answer. 
Result so far: 4261690.7
Subtracting 147 from 160 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Advancing to step 10:
If we divide 130 by 21, we get 6 and a remainder of 4.
The next digit of our result is 6. 
Result so far: 4261690.76
If we subtract 126 from 130, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 11:
The number 21 fits into 40 1 times, leaving a remainder of 19.
Record the quotient 1 as the next digit in the result. 
Result so far: 4261690.761
If we subtract 21 from 40, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

On to step 12:
The number 21 fits into 190 9 times, leaving a remainder of 1.
The next digit of our result is 9. 
Result so far: 4261690.7619
If we take 189 away from 190, 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.

On to step 13:
If we divide 10 by 21, we get 0 and a remainder of 10.
The next digit of our result is 0. 
Result so far: 4261690.7619
The remainder is 10 after subtracting 0 from 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 14:
100 divided by 21 is 4 with a remainder of 16.
Record the quotient 4 as the next digit in the result. 
Result so far: 4261690.761904
If we take 84 away from 100, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 15:
The number 21 fits into 160 7 times, leaving a remainder of 13.
Write down 7 as next digit of the result. 
Result so far: 4261690.7619047
The remainder is 13 after subtracting 147 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 16:
21 goes into 130 6 times with a remainder of 4.
The next digit of our result is 6. 
Result so far: 4261690.76190476
If we take 126 away from 130, we end up 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.

Our division results in 4261690.76190476 with a remaining 4e-09.
