We look at the division of 21563700 by 177 
Our goal is to divide 21563700 by 177.

Going ahead to step 1:
177 goes into 2 0 times with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 177

On to step 2:
21 divided by 177 is 0 with a remainder of 21.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 21 and we're left with 21.
Fetch the next digit (5) from the dividend, attach it to 21 and continue: 215 / 177

Going ahead to step 3:
215 divided by 177 is 1 with a remainder of 38.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 177 from 215 leaves us with 38.
Bring next digit (6) of the dividend behind the 38 and repeat the process: 386 / 177

Advancing to step 4:
The number 177 fits into 386 2 times, leaving a remainder of 32.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
Deduct 354 from 386 and we're left with 32.
Include the next digit (3) from the dividend after 32, then repeat: 323 / 177

On to step 5:
177 can be fit into 323 1 times, resulting in a remainder of 146.
The next digit of our result is 1. 
Result so far: 121.0
If we take 177 away from 323, we end up with 146.
Include the next digit (7) from the dividend after 146, then repeat: 1467 / 177

Advancing to step 6:
1467 divided by 177 is 8 with a remainder of 51.
Record the quotient 8 as the next digit in the result. 
Result so far: 1218.0
The remainder is 51 after subtracting 1416 from 1467.
Append the next digit (0) from the dividend to 51 and continue with: 510 / 177

Advancing to step 7:
177 goes into 510 2 times with a remainder of 156.
The next digit of our result is 2. 
Result so far: 12182.0
Deduct 354 from 510 and we're left with 156.
Grab the next digit (0) from the dividend, add it to 156, then carry on: 1560 / 177

Moving on to step 8:
When dividing 1560 by 177, we get 8 with a remainder of 144.
The next digit of our result is 8. 
Result so far: 121828.0
Deduct 1416 from 1560 and we're left with 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Step 9:
When dividing 1440 by 177, we get 8 with a remainder of 24.
Write down 8 as next digit of the result. 
Result so far: 121828.8
If we take 1416 away from 1440, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 10:
When dividing 240 by 177, we get 1 with a remainder of 63.
Use 1 as the next digit of our solution. 
Result so far: 121828.81
Deduct 177 from 240 and we're left with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Going ahead to step 11:
The number 177 fits into 630 3 times, leaving a remainder of 99.
Record the quotient 3 as the next digit in the result. 
Result so far: 121828.813
If we take 531 away from 630, we end up with 99.
Since there are no more digits in the dividend, we add a zero to the remainder making it 990, and continue the process.

Going ahead to step 12:
When dividing 990 by 177, we get 5 with a remainder of 105.
Use 5 as the next digit of our solution. 
Result so far: 121828.8135
Subtracting 885 from 990 leaves us with 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

Moving on to step 13:
When dividing 1050 by 177, we get 5 with a remainder of 165.
The next digit of our result is 5. 
Result so far: 121828.81355
Deduct 885 from 1050 and we're left with 165.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

The final outcome is 121828.81355, with a leftover of 0.000165.
