We're dividing 89846606 by 21 
We want to figure out the number of times 89846606 can be divided by 21.

On to step 1:
If we divide 8 by 21, we get 0 and a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Append the next digit (9) from the dividend to 8 and continue with: 89 / 21

Moving on to step 2:
When dividing 89 by 21, we get 4 with a remainder of 5.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
If we subtract 84 from 89, we get 5.
Bring next digit (8) of the dividend behind the 5 and repeat the process: 58 / 21

Advancing to step 3:
When dividing 58 by 21, we get 2 with a remainder of 16.
Put 2 as the next digit of the answer. 
Result so far: 42.0
If we subtract 42 from 58, we get 16.
Bring next digit (4) of the dividend behind the 16 and repeat the process: 164 / 21

Going ahead to step 4:
164 divided by 21 is 7 with a remainder of 17.
The number 7 becomes the next digit in our result. 
Result so far: 427.0
Subtract 147 from 164 to get 17.
Fetch the next digit (6) from the dividend, attach it to 17 and continue: 176 / 21

Step 5:
21 goes into 176 8 times with a remainder of 8.
Use 8 as the next digit of our solution. 
Result so far: 4278.0
Subtract 168 from 176 to get 8.
Take the next digit (6) from the dividend and append it to 8, then repeat: 86 / 21

Step 6:
21 goes into 86 4 times with a remainder of 2.
The next digit of our result is 4. 
Result so far: 42784.0
Deduct 84 from 86 and we're left with 2.
Grab the next digit (0) from the dividend, add it to 2, then carry on: 20 / 21

Moving on to step 7:
21 can be fit into 20 0 times, resulting in a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 427840.0
Deduct 0 from 20 and we're left with 20.
Append the next digit (6) from the dividend to 20 and continue with: 206 / 21

Step 8:
If we divide 206 by 21, we get 9 and a remainder of 17.
The number 9 becomes the next digit in our result. 
Result so far: 4278409.0
If we subtract 189 from 206, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Let's proceed to step 9:
When dividing 170 by 21, we get 8 with a remainder of 2.
The next digit of our result is 8. 
Result so far: 4278409.8
If we subtract 168 from 170, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 10:
20 divided by 21 is 0 with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 4278409.8
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 11:
200 divided by 21 is 9 with a remainder of 11.
The number 9 becomes the next digit in our result. 
Result so far: 4278409.809
Subtract 189 from 200 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 12:
When dividing 110 by 21, we get 5 with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 4278409.8095
The remainder is 5 after subtracting 105 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 13:
21 goes into 50 2 times with a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 4278409.80952
Deduct 42 from 50 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 14:
The number 21 fits into 80 3 times, leaving a remainder of 17.
Put 3 as the next digit of the answer. 
Result so far: 4278409.809523
If we take 63 away from 80, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Let's proceed to step 15:
When dividing 170 by 21, we get 8 with a remainder of 2.
Use 8 as the next digit of our solution. 
Result so far: 4278409.8095238
If we take 168 away from 170, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 16:
When dividing 20 by 21, we get 0 with a remainder of 20.
The next digit of our result is 0. 
Result so far: 4278409.8095238
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

In conclusion, the division gives 4278409.8095238 with a balance of 2e-08.
