We look at the division of 142945 by 83 
We want to figure out the number of times 142945 can be divided by 83.

Step 1:
1 divided by 83 is 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Append the next digit (4) from the dividend to 1 and continue with: 14 / 83

Step 2:
When dividing 14 by 83, we get 0 with a remainder of 14.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 14, we end up with 14.
Fetch the next digit (2) from the dividend, attach it to 14 and continue: 142 / 83

On to step 3:
142 divided by 83 is 1 with a remainder of 59.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 83 away from 142, we end up with 59.
Fetch the next digit (9) from the dividend, attach it to 59 and continue: 599 / 83

Going ahead to step 4:
When dividing 599 by 83, we get 7 with a remainder of 18.
Put 7 as the next digit of the answer. 
Result so far: 17.0
If we subtract 581 from 599, we get 18.
Bring next digit (4) of the dividend behind the 18 and repeat the process: 184 / 83

Step 5:
When dividing 184 by 83, we get 2 with a remainder of 18.
The next digit of our result is 2. 
Result so far: 172.0
If we subtract 166 from 184, we get 18.
Include the next digit (5) from the dividend after 18, then repeat: 185 / 83

On to step 6:
When dividing 185 by 83, we get 2 with a remainder of 19.
The number 2 becomes the next digit in our result. 
Result so far: 1722.0
Deduct 166 from 185 and we're left with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

On to step 7:
83 goes into 190 2 times with a remainder of 24.
Record the quotient 2 as the next digit in the result. 
Result so far: 1722.2
The remainder is 24 after subtracting 166 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 8:
83 can be fit into 240 2 times, resulting in a remainder of 74.
Put 2 as the next digit of the answer. 
Result so far: 1722.22
If we subtract 166 from 240, we get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Our division results in 1722.22 with a remaining 0.074.
