399051 ÷ 127 
We want to figure out the number of times 399051 can be divided by 127.

Going ahead to step 1:
3 divided by 127 is 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 127

Advancing to step 2:
127 can be fit into 39 0 times, resulting in a remainder of 39.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 39 leaves us with 39.
Append the next digit (9) from the dividend to 39 and continue with: 399 / 127

Moving on to step 3:
If we divide 399 by 127, we get 3 and a remainder of 18.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtracting 381 from 399 leaves us with 18.
Take the next digit (0) from the dividend and append it to 18, then repeat: 180 / 127

Step 4:
If we divide 180 by 127, we get 1 and a remainder of 53.
The next digit of our result is 1. 
Result so far: 31.0
If we take 127 away from 180, we end up with 53.
Include the next digit (5) from the dividend after 53, then repeat: 535 / 127

On to step 5:
If we divide 535 by 127, we get 4 and a remainder of 27.
Put 4 as the next digit of the answer. 
Result so far: 314.0
If we take 508 away from 535, we end up with 27.
Bring next digit (1) of the dividend behind the 27 and repeat the process: 271 / 127

Let's proceed to step 6:
127 goes into 271 2 times with a remainder of 17.
Record the quotient 2 as the next digit in the result. 
Result so far: 3142.0
If we take 254 away from 271, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Going ahead to step 7:
127 goes into 170 1 times with a remainder of 43.
The next digit of our result is 1. 
Result so far: 3142.1
If we subtract 127 from 170, we get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

On to step 8:
430 divided by 127 is 3 with a remainder of 49.
The number 3 becomes the next digit in our result. 
Result so far: 3142.13
The remainder is 49 after subtracting 381 from 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Advancing to step 9:
127 can be fit into 490 3 times, resulting in a remainder of 109.
Use 3 as the next digit of our solution. 
Result so far: 3142.133
The remainder is 109 after subtracting 381 from 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1090, and continue the process.

The final outcome is 3142.133, with a leftover of 0.0109.
