We look at the division of 89172159 by 622 
We want to divide 89172159 by 622.

On to step 1:
622 can be fit into 8 0 times, resulting in a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Append the next digit (9) from the dividend to 8 and continue with: 89 / 622

Moving on to step 2:
622 goes into 89 0 times with a remainder of 89.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 89 and we're left with 89.
Append the next digit (1) from the dividend to 89 and continue with: 891 / 622

On to step 3:
622 goes into 891 1 times with a remainder of 269.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 269 after subtracting 622 from 891.
Take the next digit (7) from the dividend and append it to 269, then repeat: 2697 / 622

Step 4:
The number 622 fits into 2697 4 times, leaving a remainder of 209.
Put 4 as the next digit of the answer. 
Result so far: 14.0
Deduct 2488 from 2697 and we're left with 209.
Include the next digit (2) from the dividend after 209, then repeat: 2092 / 622

Let's proceed to step 5:
622 goes into 2092 3 times with a remainder of 226.
Put 3 as the next digit of the answer. 
Result so far: 143.0
Deduct 1866 from 2092 and we're left with 226.
Grab the next digit (1) from the dividend, add it to 226, then carry on: 2261 / 622

Step 6:
2261 divided by 622 is 3 with a remainder of 395.
The number 3 becomes the next digit in our result. 
Result so far: 1433.0
If we take 1866 away from 2261, we end up with 395.
Bring next digit (5) of the dividend behind the 395 and repeat the process: 3955 / 622

On to step 7:
3955 divided by 622 is 6 with a remainder of 223.
Write down 6 as next digit of the result. 
Result so far: 14336.0
Subtracting 3732 from 3955 leaves us with 223.
Append the next digit (9) from the dividend to 223 and continue with: 2239 / 622

Advancing to step 8:
If we divide 2239 by 622, we get 3 and a remainder of 373.
The next digit of our result is 3. 
Result so far: 143363.0
If we subtract 1866 from 2239, we get 373.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3730, and continue the process.

Advancing to step 9:
If we divide 3730 by 622, we get 5 and a remainder of 620.
Write down 5 as next digit of the result. 
Result so far: 143363.5
Subtract 3110 from 3730 to get 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6200, and continue the process.

On to step 10:
622 can be fit into 6200 9 times, resulting in a remainder of 602.
The next digit of our result is 9. 
Result so far: 143363.59
Deduct 5598 from 6200 and we're left with 602.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6020, and continue the process.

Let's proceed to step 11:
The number 622 fits into 6020 9 times, leaving a remainder of 422.
The number 9 becomes the next digit in our result. 
Result so far: 143363.599
If we subtract 5598 from 6020, we get 422.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4220, and continue the process.

The final result is 143363.599 with a remainder of 0.0422.
