We look at the division of 78542 by 83 
We want to figure out the number of times 78542 can be divided by 83.

On to step 1:
If we divide 7 by 83, we get 0 and a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Fetch the next digit (8) from the dividend, attach it to 7 and continue: 78 / 83

On to step 2:
If we divide 78 by 83, we get 0 and a remainder of 78.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 78 after subtracting 0 from 78.
Take the next digit (5) from the dividend and append it to 78, then repeat: 785 / 83

Moving on to step 3:
83 can be fit into 785 9 times, resulting in a remainder of 38.
Write down 9 as next digit of the result. 
Result so far: 9.0
Subtracting 747 from 785 leaves us with 38.
Bring next digit (4) of the dividend behind the 38 and repeat the process: 384 / 83

Advancing to step 4:
When dividing 384 by 83, we get 4 with a remainder of 52.
Use 4 as the next digit of our solution. 
Result so far: 94.0
If we take 332 away from 384, we end up with 52.
Include the next digit (2) from the dividend after 52, then repeat: 522 / 83

On to step 5:
83 goes into 522 6 times with a remainder of 24.
Record the quotient 6 as the next digit in the result. 
Result so far: 946.0
Subtract 498 from 522 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 6:
240 divided by 83 is 2 with a remainder of 74.
Use 2 as the next digit of our solution. 
Result so far: 946.2
Deduct 166 from 240 and we're left with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Moving on to step 7:
The number 83 fits into 740 8 times, leaving a remainder of 76.
Write down 8 as next digit of the result. 
Result so far: 946.28
Subtracting 664 from 740 leaves us with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Let's proceed to step 8:
83 goes into 760 9 times with a remainder of 13.
Record the quotient 9 as the next digit in the result. 
Result so far: 946.289
The remainder is 13 after subtracting 747 from 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Step 9:
83 can be fit into 130 1 times, resulting in a remainder of 47.
The next digit of our result is 1. 
Result so far: 946.2891
Deduct 83 from 130 and we're left with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Let's proceed to step 10:
83 can be fit into 470 5 times, resulting in a remainder of 55.
Record the quotient 5 as the next digit in the result. 
Result so far: 946.28915
The remainder is 55 after subtracting 415 from 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Going ahead to step 11:
If we divide 550 by 83, we get 6 and a remainder of 52.
Record the quotient 6 as the next digit in the result. 
Result so far: 946.289156
Subtracting 498 from 550 leaves us 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 12:
520 divided by 83 is 6 with a remainder of 22.
Put 6 as the next digit of the answer. 
Result so far: 946.2891566
If we take 498 away from 520, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Our division results in 946.2891566 with a remaining 2.2e-07.
