We're dividing 142212 by 89 
We want to figure out the number of times 142212 can be divided by 89.

Step 1:
The number 89 fits into 1 0 times, leaving 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.
Grab the next digit (4) from the dividend, add it to 1, then carry on: 14 / 89

On to step 2:
89 goes into 14 0 times with a remainder of 14.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 14 leaves us with 14.
Include the next digit (2) from the dividend after 14, then repeat: 142 / 89

Advancing to step 3:
89 can be fit into 142 1 times, resulting in a remainder of 53.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 53 after subtracting 89 from 142.
Grab the next digit (2) from the dividend, add it to 53, then carry on: 532 / 89

On to step 4:
89 goes into 532 5 times with a remainder of 87.
Use 5 as the next digit of our solution. 
Result so far: 15.0
Subtract 445 from 532 to get 87.
Include the next digit (1) from the dividend after 87, then repeat: 871 / 89

Advancing to step 5:
If we divide 871 by 89, we get 9 and a remainder of 70.
Write down 9 as next digit of the result. 
Result so far: 159.0
If we take 801 away from 871, we end up with 70.
Take the next digit (2) from the dividend and append it to 70, then repeat: 702 / 89

Advancing to step 6:
If we divide 702 by 89, we get 7 and a remainder of 79.
Write down 7 as next digit of the result. 
Result so far: 1597.0
Deduct 623 from 702 and we're left with 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

On to step 7:
If we divide 790 by 89, we get 8 and a remainder of 78.
The next digit of our result is 8. 
Result so far: 1597.8
Subtract 712 from 790 to get 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Step 8:
780 divided by 89 is 8 with a remainder of 68.
Record the quotient 8 as the next digit in the result. 
Result so far: 1597.88
If we take 712 away from 780, we end up with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Our division results in 1597.88 with a remaining 0.068.
