We're dividing 21173308 by 117 
We want to divide 21173308 by 117.

Going ahead to step 1:
117 can be fit into 2 0 times, resulting in a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 117

On to step 2:
21 divided by 117 is 0 with a remainder of 21.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 21 and we're left with 21.
Append the next digit (1) from the dividend to 21 and continue with: 211 / 117

Let's proceed to step 3:
211 divided by 117 is 1 with a remainder of 94.
The next digit of our result is 1. 
Result so far: 1.0
If we take 117 away from 211, we end up with 94.
Fetch the next digit (7) from the dividend, attach it to 94 and continue: 947 / 117

Going ahead to step 4:
117 can be fit into 947 8 times, resulting in a remainder of 11.
The next digit of our result is 8. 
Result so far: 18.0
If we subtract 936 from 947, we get 11.
Bring next digit (3) of the dividend behind the 11 and repeat the process: 113 / 117

Moving on to step 5:
113 divided by 117 is 0 with a remainder of 113.
Record the quotient 0 as the next digit in the result. 
Result so far: 180.0
Subtracting 0 from 113 leaves us with 113.
Grab the next digit (3) from the dividend, add it to 113, then carry on: 1133 / 117

Going ahead to step 6:
If we divide 1133 by 117, we get 9 and a remainder of 80.
Write down 9 as next digit of the result. 
Result so far: 1809.0
The remainder is 80 after subtracting 1053 from 1133.
Fetch the next digit (0) from the dividend, attach it to 80 and continue: 800 / 117

Step 7:
800 divided by 117 is 6 with a remainder of 98.
Use 6 as the next digit of our solution. 
Result so far: 18096.0
Subtracting 702 from 800 leaves us with 98.
Bring next digit (8) of the dividend behind the 98 and repeat the process: 988 / 117

Advancing to step 8:
If we divide 988 by 117, we get 8 and a remainder of 52.
Record the quotient 8 as the next digit in the result. 
Result so far: 180968.0
If we take 936 away from 988, we end up with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

On to step 9:
The number 117 fits into 520 4 times, leaving a remainder of 52.
Use 4 as the next digit of our solution. 
Result so far: 180968.4
The remainder is 52 after subtracting 468 from 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Let's proceed to step 10:
520 divided by 117 is 4 with a remainder of 52.
The number 4 becomes the next digit in our result. 
Result so far: 180968.44
Subtract 468 from 520 to get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

The quotient of the division is 180968.44, and the remainder is 0.052.
