675385 ÷ 21 
We want to divide 675385 by 21.

Going ahead to step 1:
21 can be fit into 6 0 times, resulting in a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Grab the next digit (7) from the dividend, add it to 6, then carry on: 67 / 21

Moving on to step 2:
If we divide 67 by 21, we get 3 and a remainder of 4.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtracting 63 from 67 leaves us with 4.
Take the next digit (5) from the dividend and append it to 4, then repeat: 45 / 21

Going ahead to step 3:
When dividing 45 by 21, we get 2 with a remainder of 3.
Put 2 as the next digit of the answer. 
Result so far: 32.0
The remainder is 3 after subtracting 42 from 45.
Include the next digit (3) from the dividend after 3, then repeat: 33 / 21

Moving on to step 4:
If we divide 33 by 21, we get 1 and a remainder of 12.
Record the quotient 1 as the next digit in the result. 
Result so far: 321.0
Subtract 21 from 33 to get 12.
Include the next digit (8) from the dividend after 12, then repeat: 128 / 21

Advancing to step 5:
If we divide 128 by 21, we get 6 and a remainder of 2.
The number 6 becomes the next digit in our result. 
Result so far: 3216.0
The remainder is 2 after subtracting 126 from 128.
Fetch the next digit (5) from the dividend, attach it to 2 and continue: 25 / 21

On to step 6:
If we divide 25 by 21, we get 1 and a remainder of 4.
Use 1 as the next digit of our solution. 
Result so far: 32161.0
Deduct 21 from 25 and we're left 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.

Step 7:
If we divide 40 by 21, we get 1 and a remainder of 19.
The next digit of our result is 1. 
Result so far: 32161.1
Subtracting 21 from 40 leaves us 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.

Going ahead to step 8:
When dividing 190 by 21, we get 9 with a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 32161.19
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.

Going ahead to step 9:
21 can be fit into 10 0 times, resulting in a remainder of 10.
The next digit of our result is 0. 
Result so far: 32161.19
Subtract 0 from 10 to 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.

On to step 10:
21 can be fit into 100 4 times, resulting in a remainder of 16.
Put 4 as the next digit of the answer. 
Result so far: 32161.1904
Subtracting 84 from 100 leaves us 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.

Step 11:
The number 21 fits into 160 7 times, leaving a remainder of 13.
The next digit of our result is 7. 
Result so far: 32161.19047
Deduct 147 from 160 and we're left 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 12:
21 can be fit into 130 6 times, resulting in a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 32161.190476
Subtracting 126 from 130 leaves us 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.

Going ahead to step 13:
40 divided by 21 is 1 with a remainder of 19.
Record the quotient 1 as the next digit in the result. 
Result so far: 32161.1904761
Subtracting 21 from 40 leaves us 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.

Let's proceed to step 14:
21 goes into 190 9 times with a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 32161.19047619
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 32161.19047619 with a balance of 1e-09.
