369562 ÷ 21 
We want to figure out the number of times 369562 can be divided by 21.

Advancing to step 1:
21 can be fit into 3 0 times, resulting in a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Fetch the next digit (6) from the dividend, attach it to 3 and continue: 36 / 21

Step 2:
36 divided by 21 is 1 with a remainder of 15.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 21 from 36 leaves us with 15.
Append the next digit (9) from the dividend to 15 and continue with: 159 / 21

Let's proceed to step 3:
If we divide 159 by 21, we get 7 and a remainder of 12.
The next digit of our result is 7. 
Result so far: 17.0
Subtract 147 from 159 to get 12.
Bring next digit (5) of the dividend behind the 12 and repeat the process: 125 / 21

Going ahead to step 4:
21 can be fit into 125 5 times, resulting in a remainder of 20.
The next digit of our result is 5. 
Result so far: 175.0
If we take 105 away from 125, we end up with 20.
Bring next digit (6) of the dividend behind the 20 and repeat the process: 206 / 21

Step 5:
21 can be fit into 206 9 times, resulting in a remainder of 17.
Use 9 as the next digit of our solution. 
Result so far: 1759.0
The remainder is 17 after subtracting 189 from 206.
Grab the next digit (2) from the dividend, add it to 17, then carry on: 172 / 21

Moving on to step 6:
When dividing 172 by 21, we get 8 with a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 17598.0
Subtract 168 from 172 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 7:
21 can be fit into 40 1 times, resulting in a remainder of 19.
The number 1 becomes the next digit in our result. 
Result so far: 17598.1
If we take 21 away from 40, we end up 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.

Advancing to step 8:
21 goes into 190 9 times with a remainder of 1.
The next digit of our result is 9. 
Result so far: 17598.19
The remainder is 1 after subtracting 189 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 9:
21 goes into 10 0 times with a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 17598.19
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.

Moving on to step 10:
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: 17598.1904
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.

Going ahead to step 11:
The number 21 fits into 160 7 times, leaving a remainder of 13.
Put 7 as the next digit of the answer. 
Result so far: 17598.19047
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.

Advancing to step 12:
The number 21 fits into 130 6 times, leaving a remainder of 4.
Record the quotient 6 as the next digit in the result. 
Result so far: 17598.190476
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.

Step 13:
40 divided by 21 is 1 with a remainder of 19.
Use 1 as the next digit of our solution. 
Result so far: 17598.1904761
If we take 21 away from 40, we end up 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 14:
The number 21 fits into 190 9 times, leaving a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 17598.19047619
If we take 189 away from 190, we end up 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.

In conclusion, the division gives 17598.19047619 with a balance of 1e-09.
