We look at the division of 83348118 by 21 
We're looking to find how many times 21 goes into 83348118.

Let's proceed to step 1:
21 goes into 8 0 times with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Take the next digit (3) from the dividend and append it to 8, then repeat: 83 / 21

Moving on to step 2:
83 divided by 21 is 3 with a remainder of 20.
Use 3 as the next digit of our solution. 
Result so far: 3.0
The remainder is 20 after subtracting 63 from 83.
Include the next digit (3) from the dividend after 20, then repeat: 203 / 21

Moving on to step 3:
21 goes into 203 9 times with a remainder of 14.
Use 9 as the next digit of our solution. 
Result so far: 39.0
If we subtract 189 from 203, we get 14.
Include the next digit (4) from the dividend after 14, then repeat: 144 / 21

Let's proceed to step 4:
If we divide 144 by 21, we get 6 and a remainder of 18.
Use 6 as the next digit of our solution. 
Result so far: 396.0
Subtract 126 from 144 to get 18.
Take the next digit (8) from the dividend and append it to 18, then repeat: 188 / 21

Let's proceed to step 5:
188 divided by 21 is 8 with a remainder of 20.
Use 8 as the next digit of our solution. 
Result so far: 3968.0
Subtract 168 from 188 to get 20.
Take the next digit (1) from the dividend and append it to 20, then repeat: 201 / 21

Going ahead to step 6:
The number 21 fits into 201 9 times, leaving a remainder of 12.
Put 9 as the next digit of the answer. 
Result so far: 39689.0
If we subtract 189 from 201, we get 12.
Bring next digit (1) of the dividend behind the 12 and repeat the process: 121 / 21

Step 7:
When dividing 121 by 21, we get 5 with a remainder of 16.
The number 5 becomes the next digit in our result. 
Result so far: 396895.0
Subtracting 105 from 121 leaves us with 16.
Append the next digit (8) from the dividend to 16 and continue with: 168 / 21

Let's proceed to step 8:
If we divide 168 by 21, we get 8 and a remainder of 0.
The next digit of our result is 8. 
Result so far: 3968958.0
Subtracting 168 from 168 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 9:
If we divide 0 by 21, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 3968958.0
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 10:
21 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 3968958.0
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 3968958.0 and a remainder of 0.0.
