We look at the division of 674598 by 21 
Our goal is to divide 674598 by 21.

Advancing to step 1:
When dividing 6 by 21, we get 0 with 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.
Bring next digit (7) of the dividend behind the 6 and repeat the process: 67 / 21

Advancing to step 2:
The number 21 fits into 67 3 times, leaving a remainder of 4.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we take 63 away from 67, we end up with 4.
Include the next digit (4) from the dividend after 4, then repeat: 44 / 21

Step 3:
When dividing 44 by 21, we get 2 with a remainder of 2.
Write down 2 as next digit of the result. 
Result so far: 32.0
Subtracting 42 from 44 leaves us with 2.
Append the next digit (5) from the dividend to 2 and continue with: 25 / 21

Going ahead to step 4:
21 goes into 25 1 times with a remainder of 4.
Record the quotient 1 as the next digit in the result. 
Result so far: 321.0
The remainder is 4 after subtracting 21 from 25.
Append the next digit (9) from the dividend to 4 and continue with: 49 / 21

Let's proceed to step 5:
If we divide 49 by 21, we get 2 and a remainder of 7.
Use 2 as the next digit of our solution. 
Result so far: 3212.0
Deduct 42 from 49 and we're left with 7.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 21

Step 6:
21 goes into 78 3 times with a remainder of 15.
Write down 3 as next digit of the result. 
Result so far: 32123.0
Deduct 63 from 78 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.

Let's proceed to step 7:
21 goes into 150 7 times with a remainder of 3.
Put 7 as the next digit of the answer. 
Result so far: 32123.7
Subtracting 147 from 150 leaves us 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.

Advancing to step 8:
When dividing 30 by 21, we get 1 with a remainder of 9.
Put 1 as the next digit of the answer. 
Result so far: 32123.71
The remainder is 9 after subtracting 21 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 9:
21 goes into 90 4 times with a remainder of 6.
The number 4 becomes the next digit in our result. 
Result so far: 32123.714
Deduct 84 from 90 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 10:
21 goes into 60 2 times with a remainder of 18.
Write down 2 as next digit of the result. 
Result so far: 32123.7142
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.

Moving on to step 11:
When dividing 180 by 21, we get 8 with a remainder of 12.
The number 8 becomes the next digit in our result. 
Result so far: 32123.71428
The remainder is 12 after subtracting 168 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 12:
When dividing 120 by 21, we get 5 with a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 32123.714285
The remainder is 15 after subtracting 105 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 13:
21 can be fit into 150 7 times, resulting in a remainder of 3.
Put 7 as the next digit of the answer. 
Result so far: 32123.7142857
Subtracting 147 from 150 leaves us 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.

On to step 14:
21 can be fit into 30 1 times, resulting in a remainder of 9.
Record the quotient 1 as the next digit in the result. 
Result so far: 32123.71428571
If we take 21 away from 30, we end up 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.

In conclusion, the division gives 32123.71428571 with a balance of 9e-09.
