193352 divided by 21 
We're looking to find how many times 21 goes into 193352.

On to step 1:
21 can be fit into 1 0 times, resulting in a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Bring next digit (9) of the dividend behind the 1 and repeat the process: 19 / 21

Advancing to step 2:
19 divided by 21 is 0 with a remainder of 19.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 19 leaves us with 19.
Take the next digit (3) from the dividend and append it to 19, then repeat: 193 / 21

Let's proceed to step 3:
193 divided by 21 is 9 with a remainder of 4.
The next digit of our result is 9. 
Result so far: 9.0
Subtract 189 from 193 to get 4.
Take the next digit (3) from the dividend and append it to 4, then repeat: 43 / 21

Let's proceed to step 4:
The number 21 fits into 43 2 times, leaving a remainder of 1.
The next digit of our result is 2. 
Result so far: 92.0
If we take 42 away from 43, we end up with 1.
Fetch the next digit (5) from the dividend, attach it to 1 and continue: 15 / 21

Let's proceed to step 5:
When dividing 15 by 21, we get 0 with a remainder of 15.
The number 0 becomes the next digit in our result. 
Result so far: 920.0
Subtract 0 from 15 to get 15.
Take the next digit (2) from the dividend and append it to 15, then repeat: 152 / 21

On to step 6:
The number 21 fits into 152 7 times, leaving a remainder of 5.
The number 7 becomes the next digit in our result. 
Result so far: 9207.0
The remainder is 5 after subtracting 147 from 152.
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 7:
50 divided by 21 is 2 with a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 9207.2
The remainder is 8 after subtracting 42 from 50.
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 8:
80 divided by 21 is 3 with a remainder of 17.
Write down 3 as next digit of the result. 
Result so far: 9207.23
Subtracting 63 from 80 leaves us 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.

Advancing to step 9:
21 can be fit into 170 8 times, resulting in a remainder of 2.
The number 8 becomes the next digit in our result. 
Result so far: 9207.238
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.

Let's proceed to step 10:
20 divided by 21 is 0 with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 9207.238
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 11:
When dividing 200 by 21, we get 9 with a remainder of 11.
Record the quotient 9 as the next digit in the result. 
Result so far: 9207.23809
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.

Going ahead to step 12:
21 goes into 110 5 times with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 9207.238095
Subtract 105 from 110 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 13:
21 can be fit into 50 2 times, resulting in a remainder of 8.
The next digit of our result is 2. 
Result so far: 9207.2380952
If we take 42 away from 50, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 14:
21 goes into 80 3 times with a remainder of 17.
Use 3 as the next digit of our solution. 
Result so far: 9207.23809523
Subtracting 63 from 80 leaves us 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.

After the division, we end up with 9207.23809523 and a remainder of 1.7e-08.
