We're dividing 917347 by 21 
Our goal is to divide 917347 by 21.

Going ahead to step 1:
21 can be fit into 9 0 times, resulting in a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Append the next digit (1) from the dividend to 9 and continue with: 91 / 21

Moving on to step 2:
21 can be fit into 91 4 times, resulting in a remainder of 7.
The next digit of our result is 4. 
Result so far: 4.0
Deduct 84 from 91 and we're left with 7.
Bring next digit (7) of the dividend behind the 7 and repeat the process: 77 / 21

Going ahead to step 3:
The number 21 fits into 77 3 times, leaving a remainder of 14.
The number 3 becomes the next digit in our result. 
Result so far: 43.0
Subtract 63 from 77 to get 14.
Append the next digit (3) from the dividend to 14 and continue with: 143 / 21

On to step 4:
21 can be fit into 143 6 times, resulting in a remainder of 17.
Use 6 as the next digit of our solution. 
Result so far: 436.0
The remainder is 17 after subtracting 126 from 143.
Include the next digit (4) from the dividend after 17, then repeat: 174 / 21

Moving on to step 5:
21 can be fit into 174 8 times, resulting in a remainder of 6.
Write down 8 as next digit of the result. 
Result so far: 4368.0
Subtracting 168 from 174 leaves us with 6.
Take the next digit (7) from the dividend and append it to 6, then repeat: 67 / 21

Advancing to step 6:
21 can be fit into 67 3 times, resulting in a remainder of 4.
Use 3 as the next digit of our solution. 
Result so far: 43683.0
If we take 63 away from 67, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 7:
When dividing 40 by 21, we get 1 with a remainder of 19.
Use 1 as the next digit of our solution. 
Result so far: 43683.1
Deduct 21 from 40 and we're left with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Moving on to step 8:
When dividing 190 by 21, we get 9 with a remainder of 1.
The next digit of our result is 9. 
Result so far: 43683.19
Deduct 189 from 190 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 9:
When dividing 10 by 21, we get 0 with a remainder of 10.
The next digit of our result is 0. 
Result so far: 43683.19
Subtracting 0 from 10 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 10:
21 goes into 100 4 times with a remainder of 16.
Use 4 as the next digit of our solution. 
Result so far: 43683.1904
Deduct 84 from 100 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 11:
21 goes into 160 7 times with a remainder of 13.
The number 7 becomes the next digit in our result. 
Result so far: 43683.19047
Subtract 147 from 160 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

On to step 12:
21 goes into 130 6 times with a remainder of 4.
Use 6 as the next digit of our solution. 
Result so far: 43683.190476
If we subtract 126 from 130, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 13:
40 divided by 21 is 1 with a remainder of 19.
The number 1 becomes the next digit in our result. 
Result so far: 43683.1904761
The remainder is 19 after subtracting 21 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

On to step 14:
21 goes into 190 9 times with a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 43683.19047619
If we subtract 189 from 190, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

In conclusion, the division gives 43683.19047619 with a balance of 1e-09.
