We're dividing 690161 by 21 
We want to divide 690161 by 21.

Moving on to step 1:
If we divide 6 by 21, we get 0 and a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Take the next digit (9) from the dividend and append it to 6, then repeat: 69 / 21

On to step 2:
When dividing 69 by 21, we get 3 with a remainder of 6.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
If we subtract 63 from 69, we get 6.
Grab the next digit (0) from the dividend, add it to 6, then carry on: 60 / 21

On to step 3:
60 divided by 21 is 2 with a remainder of 18.
Record the quotient 2 as the next digit in the result. 
Result so far: 32.0
Subtracting 42 from 60 leaves us with 18.
Take the next digit (1) from the dividend and append it to 18, then repeat: 181 / 21

Going ahead to step 4:
21 can be fit into 181 8 times, resulting in a remainder of 13.
Put 8 as the next digit of the answer. 
Result so far: 328.0
If we take 168 away from 181, we end up with 13.
Take the next digit (6) from the dividend and append it to 13, then repeat: 136 / 21

Advancing to step 5:
21 can be fit into 136 6 times, resulting in a remainder of 10.
The next digit of our result is 6. 
Result so far: 3286.0
The remainder is 10 after subtracting 126 from 136.
Take the next digit (1) from the dividend and append it to 10, then repeat: 101 / 21

On to step 6:
101 divided by 21 is 4 with a remainder of 17.
The next digit of our result is 4. 
Result so far: 32864.0
Deduct 84 from 101 and we're left with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Moving on to step 7:
21 can be fit into 170 8 times, resulting in a remainder of 2.
Write down 8 as next digit of the result. 
Result so far: 32864.8
If we subtract 168 from 170, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 8:
The number 21 fits into 20 0 times, leaving a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 32864.8
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 9:
If we divide 200 by 21, we get 9 and a remainder of 11.
Use 9 as the next digit of our solution. 
Result so far: 32864.809
If we subtract 189 from 200, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Let's proceed to step 10:
The number 21 fits into 110 5 times, leaving a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 32864.8095
Subtracting 105 from 110 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 11:
The number 21 fits into 50 2 times, leaving a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 32864.80952
If we subtract 42 from 50, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 12:
21 goes into 80 3 times with a remainder of 17.
The next digit of our result is 3. 
Result so far: 32864.809523
If we subtract 63 from 80, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Advancing to step 13:
When dividing 170 by 21, we get 8 with a remainder of 2.
The next digit of our result is 8. 
Result so far: 32864.8095238
If we subtract 168 from 170, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 14:
21 goes into 20 0 times with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 32864.8095238
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The quotient of the division is 32864.8095238, and the remainder is 2e-08.
