We're dividing 48143857 by 341 
We want to figure out the number of times 48143857 can be divided by 341.

Going ahead to step 1:
The number 341 fits into 4 0 times, leaving a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Append the next digit (8) from the dividend to 4 and continue with: 48 / 341

Going ahead to step 2:
341 can be fit into 48 0 times, resulting in a remainder of 48.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 48 and we're left with 48.
Append the next digit (1) from the dividend to 48 and continue with: 481 / 341

Moving on to step 3:
341 goes into 481 1 times with a remainder of 140.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 341 from 481, we get 140.
Take the next digit (4) from the dividend and append it to 140, then repeat: 1404 / 341

Advancing to step 4:
341 goes into 1404 4 times with a remainder of 40.
Write down 4 as next digit of the result. 
Result so far: 14.0
The remainder is 40 after subtracting 1364 from 1404.
Bring next digit (3) of the dividend behind the 40 and repeat the process: 403 / 341

Step 5:
The number 341 fits into 403 1 times, leaving a remainder of 62.
The next digit of our result is 1. 
Result so far: 141.0
If we subtract 341 from 403, we get 62.
Bring next digit (8) of the dividend behind the 62 and repeat the process: 628 / 341

On to step 6:
341 can be fit into 628 1 times, resulting in a remainder of 287.
The next digit of our result is 1. 
Result so far: 1411.0
Deduct 341 from 628 and we're left with 287.
Include the next digit (5) from the dividend after 287, then repeat: 2875 / 341

On to step 7:
When dividing 2875 by 341, we get 8 with a remainder of 147.
Record the quotient 8 as the next digit in the result. 
Result so far: 14118.0
The remainder is 147 after subtracting 2728 from 2875.
Bring next digit (7) of the dividend behind the 147 and repeat the process: 1477 / 341

On to step 8:
The number 341 fits into 1477 4 times, leaving a remainder of 113.
The next digit of our result is 4. 
Result so far: 141184.0
Subtract 1364 from 1477 to get 113.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1130, and continue the process.

Step 9:
341 can be fit into 1130 3 times, resulting in a remainder of 107.
Write down 3 as next digit of the result. 
Result so far: 141184.3
Subtracting 1023 from 1130 leaves us with 107.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1070, and continue the process.

On to step 10:
When dividing 1070 by 341, we get 3 with a remainder of 47.
Write down 3 as next digit of the result. 
Result so far: 141184.33
Subtracting 1023 from 1070 leaves us 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.

The final result is 141184.33 with a remainder of 0.047.
