96199373 divided by 21 
We want to divide 96199373 by 21.

Let's proceed to step 1:
When dividing 9 by 21, we get 0 with a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Fetch the next digit (6) from the dividend, attach it to 9 and continue: 96 / 21

Going ahead to step 2:
If we divide 96 by 21, we get 4 and a remainder of 12.
The next digit of our result is 4. 
Result so far: 4.0
If we take 84 away from 96, we end up with 12.
Include the next digit (1) from the dividend after 12, then repeat: 121 / 21

On to step 3:
21 goes into 121 5 times with a remainder of 16.
The next digit of our result is 5. 
Result so far: 45.0
The remainder is 16 after subtracting 105 from 121.
Include the next digit (9) from the dividend after 16, then repeat: 169 / 21

On to step 4:
169 divided by 21 is 8 with a remainder of 1.
Use 8 as the next digit of our solution. 
Result so far: 458.0
Deduct 168 from 169 and we're left with 1.
Fetch the next digit (9) from the dividend, attach it to 1 and continue: 19 / 21

Let's proceed to step 5:
21 goes into 19 0 times with a remainder of 19.
The number 0 becomes the next digit in our result. 
Result so far: 4580.0
Deduct 0 from 19 and we're left with 19.
Include the next digit (3) from the dividend after 19, then repeat: 193 / 21

Step 6:
If we divide 193 by 21, we get 9 and a remainder of 4.
Record the quotient 9 as the next digit in the result. 
Result so far: 45809.0
Subtracting 189 from 193 leaves us with 4.
Include the next digit (7) from the dividend after 4, then repeat: 47 / 21

Let's proceed to step 7:
21 goes into 47 2 times with a remainder of 5.
Record the quotient 2 as the next digit in the result. 
Result so far: 458092.0
Deduct 42 from 47 and we're left with 5.
Grab the next digit (3) from the dividend, add it to 5, then carry on: 53 / 21

Moving on to step 8:
21 goes into 53 2 times with a remainder of 11.
Put 2 as the next digit of the answer. 
Result so far: 4580922.0
Subtract 42 from 53 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.

Moving on to step 9:
21 goes into 110 5 times with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 4580922.5
If we subtract 105 from 110, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 10:
If we divide 50 by 21, we get 2 and a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 4580922.52
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.

Advancing to step 11:
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: 4580922.523
Subtract 63 from 80 to 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.

Moving on to step 12:
21 can be fit into 170 8 times, resulting in a remainder of 2.
The next digit of our result is 8. 
Result so far: 4580922.5238
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.

Moving on to step 13:
The number 21 fits into 20 0 times, leaving a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 4580922.5238
If we subtract 0 from 20, we 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 14:
21 can be fit into 200 9 times, resulting in a remainder of 11.
The number 9 becomes the next digit in our result. 
Result so far: 4580922.523809
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.

Step 15:
If we divide 110 by 21, we get 5 and a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 4580922.5238095
Subtract 105 from 110 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 16:
When dividing 50 by 21, we get 2 with a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 4580922.52380952
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.

In conclusion, the division gives 4580922.52380952 with a balance of 8e-09.
