We look at the division of 545156 by 42 
We want to figure out the number of times 545156 can be divided by 42.

Advancing to step 1:
42 can be fit into 5 0 times, resulting in a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Grab the next digit (4) from the dividend, add it to 5, then carry on: 54 / 42

On to step 2:
If we divide 54 by 42, we get 1 and a remainder of 12.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 42 from 54 leaves us with 12.
Include the next digit (5) from the dividend after 12, then repeat: 125 / 42

Going ahead to step 3:
If we divide 125 by 42, we get 2 and a remainder of 41.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
Deduct 84 from 125 and we're left with 41.
Take the next digit (1) from the dividend and append it to 41, then repeat: 411 / 42

Step 4:
42 goes into 411 9 times with a remainder of 33.
Put 9 as the next digit of the answer. 
Result so far: 129.0
If we subtract 378 from 411, we get 33.
Take the next digit (5) from the dividend and append it to 33, then repeat: 335 / 42

On to step 5:
42 can be fit into 335 7 times, resulting in a remainder of 41.
Record the quotient 7 as the next digit in the result. 
Result so far: 1297.0
Subtract 294 from 335 to get 41.
Take the next digit (6) from the dividend and append it to 41, then repeat: 416 / 42

On to step 6:
416 divided by 42 is 9 with a remainder of 38.
The next digit of our result is 9. 
Result so far: 12979.0
The remainder is 38 after subtracting 378 from 416.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Let's proceed to step 7:
380 divided by 42 is 9 with a remainder of 2.
Use 9 as the next digit of our solution. 
Result so far: 12979.9
Subtracting 378 from 380 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 8:
If we divide 20 by 42, we get 0 and a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 12979.9
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 9:
When dividing 200 by 42, we get 4 with a remainder of 32.
The number 4 becomes the next digit in our result. 
Result so far: 12979.904
If we subtract 168 from 200, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 10:
42 can be fit into 320 7 times, resulting in a remainder of 26.
Use 7 as the next digit of our solution. 
Result so far: 12979.9047
Subtracting 294 from 320 leaves us with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Advancing to step 11:
42 can be fit into 260 6 times, resulting in a remainder of 8.
Use 6 as the next digit of our solution. 
Result so far: 12979.90476
If we subtract 252 from 260, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 12:
When dividing 80 by 42, we get 1 with a remainder of 38.
The next digit of our result is 1. 
Result so far: 12979.904761
Subtracting 42 from 80 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

On to step 13:
When dividing 380 by 42, we get 9 with a remainder of 2.
The number 9 becomes the next digit in our result. 
Result so far: 12979.9047619
If we take 378 away from 380, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 14:
When dividing 20 by 42, we get 0 with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 12979.9047619
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

After the division, we end up with 12979.9047619 and a remainder of 2e-08.
