We look at the division of 48545 by 42 
We're looking to find how many times 42 goes into 48545.

Going ahead to step 1:
The number 42 fits into 4 0 times, leaving a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Include the next digit (8) from the dividend after 4, then repeat: 48 / 42

Moving on to step 2:
42 can be fit into 48 1 times, resulting in a remainder of 6.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 42 from 48 to get 6.
Grab the next digit (5) from the dividend, add it to 6, then carry on: 65 / 42

On to step 3:
42 goes into 65 1 times with a remainder of 23.
Use 1 as the next digit of our solution. 
Result so far: 11.0
If we subtract 42 from 65, we get 23.
Append the next digit (4) from the dividend to 23 and continue with: 234 / 42

Moving on to step 4:
42 goes into 234 5 times with a remainder of 24.
Put 5 as the next digit of the answer. 
Result so far: 115.0
The remainder is 24 after subtracting 210 from 234.
Grab the next digit (5) from the dividend, add it to 24, then carry on: 245 / 42

Advancing to step 5:
When dividing 245 by 42, we get 5 with a remainder of 35.
Write down 5 as next digit of the result. 
Result so far: 1155.0
Deduct 210 from 245 and we're left with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Advancing to step 6:
The number 42 fits into 350 8 times, leaving a remainder of 14.
Put 8 as the next digit of the answer. 
Result so far: 1155.8
Subtracting 336 from 350 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 7:
If we divide 140 by 42, we get 3 and a remainder of 14.
Use 3 as the next digit of our solution. 
Result so far: 1155.83
If we take 126 away from 140, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 8:
42 can be fit into 140 3 times, resulting in a remainder of 14.
Put 3 as the next digit of the answer. 
Result so far: 1155.833
If we take 126 away from 140, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

The final outcome is 1155.833, with a leftover of 0.0014.
