Let's divide 968253 by 21
We're looking to find how many times 21 goes into 968253.

Going ahead to step 1:
If we divide 9 by 21, we get 0 and a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Take the next digit (6) from the dividend and append it to 9, then repeat: 96 / 21

Let's proceed to step 2:
21 can be fit into 96 4 times, resulting in a remainder of 12.
Write down 4 as next digit of the result. 
Result so far: 4.0
Deduct 84 from 96 and we're left with 12.
Take the next digit (8) from the dividend and append it to 12, then repeat: 128 / 21

Advancing to step 3:
When dividing 128 by 21, we get 6 with a remainder of 2.
Use 6 as the next digit of our solution. 
Result so far: 46.0
Subtract 126 from 128 to get 2.
Append the next digit (2) from the dividend to 2 and continue with: 22 / 21

Advancing to step 4:
The number 21 fits into 22 1 times, leaving a remainder of 1.
The next digit of our result is 1. 
Result so far: 461.0
Subtracting 21 from 22 leaves us with 1.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 21

Going ahead to step 5:
21 can be fit into 15 0 times, resulting in a remainder of 15.
The next digit of our result is 0. 
Result so far: 4610.0
If we take 0 away from 15, we end up with 15.
Grab the next digit (3) from the dividend, add it to 15, then carry on: 153 / 21

Going ahead to step 6:
If we divide 153 by 21, we get 7 and a remainder of 6.
Record the quotient 7 as the next digit in the result. 
Result so far: 46107.0
The remainder is 6 after subtracting 147 from 153.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 7:
The number 21 fits into 60 2 times, leaving a remainder of 18.
The next digit of our result is 2. 
Result so far: 46107.2
The remainder is 18 after subtracting 42 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 8:
21 goes into 180 8 times with a remainder of 12.
The number 8 becomes the next digit in our result. 
Result so far: 46107.28
Deduct 168 from 180 and we're left 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.

Advancing to step 9:
21 goes into 120 5 times with a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 46107.285
Deduct 105 from 120 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 10:
The number 21 fits into 150 7 times, leaving a remainder of 3.
Use 7 as the next digit of our solution. 
Result so far: 46107.2857
If we take 147 away from 150, we end up 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.

Step 11:
If we divide 30 by 21, we get 1 and a remainder of 9.
Write down 1 as next digit of the result. 
Result so far: 46107.28571
Subtracting 21 from 30 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.

Step 12:
If we divide 90 by 21, we get 4 and a remainder of 6.
Write down 4 as next digit of the result. 
Result so far: 46107.285714
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.

Advancing to step 13:
If we divide 60 by 21, we get 2 and a remainder of 18.
The next digit of our result is 2. 
Result so far: 46107.2857142
If we take 42 away from 60, we end up 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.

Advancing to step 14:
180 divided by 21 is 8 with a remainder of 12.
Use 8 as the next digit of our solution. 
Result so far: 46107.28571428
If we take 168 away from 180, we end up 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.

The final result is 46107.28571428 with a remainder of 1.2e-08.
