We divide 978798 by 21
We're looking to find how many times 21 goes into 978798.

Let's proceed to step 1:
9 divided by 21 is 0 with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Take the next digit (7) from the dividend and append it to 9, then repeat: 97 / 21

Advancing to step 2:
When dividing 97 by 21, we get 4 with a remainder of 13.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Subtract 84 from 97 to get 13.
Take the next digit (8) from the dividend and append it to 13, then repeat: 138 / 21

Moving on to step 3:
The number 21 fits into 138 6 times, leaving a remainder of 12.
The number 6 becomes the next digit in our result. 
Result so far: 46.0
Subtracting 126 from 138 leaves us with 12.
Take the next digit (7) from the dividend and append it to 12, then repeat: 127 / 21

Advancing to step 4:
21 can be fit into 127 6 times, resulting in a remainder of 1.
Use 6 as the next digit of our solution. 
Result so far: 466.0
If we take 126 away from 127, we end up with 1.
Grab the next digit (9) from the dividend, add it to 1, then carry on: 19 / 21

Let's proceed to step 5:
19 divided by 21 is 0 with a remainder of 19.
Record the quotient 0 as the next digit in the result. 
Result so far: 4660.0
Subtract 0 from 19 to get 19.
Include the next digit (8) from the dividend after 19, then repeat: 198 / 21

On to step 6:
The number 21 fits into 198 9 times, leaving a remainder of 9.
The number 9 becomes the next digit in our result. 
Result so far: 46609.0
Subtracting 189 from 198 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 7:
If we divide 90 by 21, we get 4 and a remainder of 6.
The number 4 becomes the next digit in our result. 
Result so far: 46609.4
Subtracting 84 from 90 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 8:
21 can be fit into 60 2 times, resulting in a remainder of 18.
Put 2 as the next digit of the answer. 
Result so far: 46609.42
Subtract 42 from 60 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 9:
180 divided by 21 is 8 with a remainder of 12.
Use 8 as the next digit of our solution. 
Result so far: 46609.428
Subtracting 168 from 180 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 10:
If we divide 120 by 21, we get 5 and a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 46609.4285
If we subtract 105 from 120, we 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 11:
When dividing 150 by 21, we get 7 with a remainder of 3.
Record the quotient 7 as the next digit in the result. 
Result so far: 46609.42857
Subtracting 147 from 150 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 12:
21 goes into 30 1 times with a remainder of 9.
The next digit of our result is 1. 
Result so far: 46609.428571
If we take 21 away from 30, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 13:
When dividing 90 by 21, we get 4 with a remainder of 6.
Record the quotient 4 as the next digit in the result. 
Result so far: 46609.4285714
If we subtract 84 from 90, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 14:
21 goes into 60 2 times with a remainder of 18.
The next digit of our result is 2. 
Result so far: 46609.42857142
Deduct 42 from 60 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

In conclusion, the division gives 46609.42857142 with a balance of 1.8e-08.
