We're dividing 97394105 by 21 
We want to figure out the number of times 97394105 can be divided by 21.

Going ahead 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.
Bring next digit (7) of the dividend behind the 9 and repeat the process: 97 / 21

Moving on to step 2:
21 goes into 97 4 times with a remainder of 13.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
If we subtract 84 from 97, we get 13.
Include the next digit (3) from the dividend after 13, then repeat: 133 / 21

Moving on to step 3:
If we divide 133 by 21, we get 6 and a remainder of 7.
Use 6 as the next digit of our solution. 
Result so far: 46.0
The remainder is 7 after subtracting 126 from 133.
Append the next digit (9) from the dividend to 7 and continue with: 79 / 21

Let's proceed to step 4:
If we divide 79 by 21, we get 3 and a remainder of 16.
Record the quotient 3 as the next digit in the result. 
Result so far: 463.0
Subtracting 63 from 79 leaves us with 16.
Append the next digit (4) from the dividend to 16 and continue with: 164 / 21

On to step 5:
21 can be fit into 164 7 times, resulting in a remainder of 17.
Write down 7 as next digit of the result. 
Result so far: 4637.0
Subtract 147 from 164 to get 17.
Grab the next digit (1) from the dividend, add it to 17, then carry on: 171 / 21

Let's proceed to step 6:
The number 21 fits into 171 8 times, leaving a remainder of 3.
The number 8 becomes the next digit in our result. 
Result so far: 46378.0
Subtract 168 from 171 to get 3.
Bring next digit (0) of the dividend behind the 3 and repeat the process: 30 / 21

Let's proceed to step 7:
When dividing 30 by 21, we get 1 with a remainder of 9.
Write down 1 as next digit of the result. 
Result so far: 463781.0
Subtract 21 from 30 to get 9.
Append the next digit (5) from the dividend to 9 and continue with: 95 / 21

Let's proceed to step 8:
21 goes into 95 4 times with a remainder of 11.
Record the quotient 4 as the next digit in the result. 
Result so far: 4637814.0
Deduct 84 from 95 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Let's proceed to step 9:
21 goes into 110 5 times with a remainder of 5.
The next digit of our result is 5. 
Result so far: 4637814.5
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.

Moving on to step 10:
50 divided by 21 is 2 with a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 4637814.52
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.

Let's proceed to step 11:
21 can be fit into 80 3 times, resulting in a remainder of 17.
Use 3 as the next digit of our solution. 
Result so far: 4637814.523
Deduct 63 from 80 and we're left 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.

Going ahead to step 12:
If we divide 170 by 21, we get 8 and a remainder of 2.
Write down 8 as next digit of the result. 
Result so far: 4637814.5238
Subtracting 168 from 170 leaves us 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 13:
21 goes into 20 0 times with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 4637814.5238
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 14:
21 goes into 200 9 times with a remainder of 11.
Use 9 as the next digit of our solution. 
Result so far: 4637814.523809
If we take 189 away from 200, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 15:
When dividing 110 by 21, we get 5 with a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 4637814.5238095
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.

Step 16:
21 goes into 50 2 times with a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 4637814.52380952
If we subtract 42 from 50, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Our division results in 4637814.52380952 with a remaining 8e-09.
