We're dividing 675685 by 21 
Let's see how many times 21 fits into 675685.

Advancing to step 1:
If we divide 6 by 21, we get 0 and a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Append the next digit (7) from the dividend to 6 and continue with: 67 / 21

Let's proceed to step 2:
21 goes into 67 3 times with a remainder of 4.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we subtract 63 from 67, we get 4.
Take the next digit (5) from the dividend and append it to 4, then repeat: 45 / 21

On to step 3:
If we divide 45 by 21, we get 2 and a remainder of 3.
Use 2 as the next digit of our solution. 
Result so far: 32.0
If we take 42 away from 45, we end up with 3.
Take the next digit (6) from the dividend and append it to 3, then repeat: 36 / 21

Advancing to step 4:
36 divided by 21 is 1 with a remainder of 15.
Use 1 as the next digit of our solution. 
Result so far: 321.0
Deduct 21 from 36 and we're left with 15.
Append the next digit (8) from the dividend to 15 and continue with: 158 / 21

Going ahead to step 5:
If we divide 158 by 21, we get 7 and a remainder of 11.
The number 7 becomes the next digit in our result. 
Result so far: 3217.0
The remainder is 11 after subtracting 147 from 158.
Grab the next digit (5) from the dividend, add it to 11, then carry on: 115 / 21

Step 6:
When dividing 115 by 21, we get 5 with a remainder of 10.
The next digit of our result is 5. 
Result so far: 32175.0
If we take 105 away from 115, we end up 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.

Step 7:
The number 21 fits into 100 4 times, leaving a remainder of 16.
Record the quotient 4 as the next digit in the result. 
Result so far: 32175.4
If we take 84 away from 100, we end up 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.

Going ahead to step 8:
21 can be fit into 160 7 times, resulting in a remainder of 13.
The next digit of our result is 7. 
Result so far: 32175.47
Subtracting 147 from 160 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Moving on to step 9:
21 can be fit into 130 6 times, resulting in a remainder of 4.
The next digit of our result is 6. 
Result so far: 32175.476
Subtract 126 from 130 to 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.

Step 10:
If we divide 40 by 21, we get 1 and a remainder of 19.
Put 1 as the next digit of the answer. 
Result so far: 32175.4761
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.

Going ahead to step 11:
21 can be fit into 190 9 times, resulting in a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 32175.47619
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.

Advancing to step 12:
The number 21 fits into 10 0 times, leaving a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 32175.47619
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 13:
21 goes into 100 4 times with a remainder of 16.
The number 4 becomes the next digit in our result. 
Result so far: 32175.4761904
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.

Going ahead to step 14:
21 can be fit into 160 7 times, resulting in a remainder of 13.
The number 7 becomes the next digit in our result. 
Result so far: 32175.47619047
If we subtract 147 from 160, we 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.

In conclusion, the division gives 32175.47619047 with a balance of 1.3e-08.
