We look at the division of 41397257 by 857 
We want to divide 41397257 by 857.

Going ahead to step 1:
When dividing 4 by 857, we get 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Bring next digit (1) of the dividend behind the 4 and repeat the process: 41 / 857

Let's proceed to step 2:
The number 857 fits into 41 0 times, leaving a remainder of 41.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 41 leaves us with 41.
Grab the next digit (3) from the dividend, add it to 41, then carry on: 413 / 857

Let's proceed to step 3:
The number 857 fits into 413 0 times, leaving a remainder of 413.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 413, we get 413.
Grab the next digit (9) from the dividend, add it to 413, then carry on: 4139 / 857

Advancing to step 4:
When dividing 4139 by 857, we get 4 with a remainder of 711.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtracting 3428 from 4139 leaves us with 711.
Include the next digit (7) from the dividend after 711, then repeat: 7117 / 857

On to step 5:
When dividing 7117 by 857, we get 8 with a remainder of 261.
Use 8 as the next digit of our solution. 
Result so far: 48.0
Subtract 6856 from 7117 to get 261.
Grab the next digit (2) from the dividend, add it to 261, then carry on: 2612 / 857

Moving on to step 6:
When dividing 2612 by 857, we get 3 with a remainder of 41.
The number 3 becomes the next digit in our result. 
Result so far: 483.0
Deduct 2571 from 2612 and we're left with 41.
Include the next digit (5) from the dividend after 41, then repeat: 415 / 857

Going ahead to step 7:
857 can be fit into 415 0 times, resulting in a remainder of 415.
Write down 0 as next digit of the result. 
Result so far: 4830.0
Subtracting 0 from 415 leaves us with 415.
Take the next digit (7) from the dividend and append it to 415, then repeat: 4157 / 857

Moving on to step 8:
857 can be fit into 4157 4 times, resulting in a remainder of 729.
The next digit of our result is 4. 
Result so far: 48304.0
If we take 3428 away from 4157, we end up with 729.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7290, and continue the process.

On to step 9:
857 can be fit into 7290 8 times, resulting in a remainder of 434.
The next digit of our result is 8. 
Result so far: 48304.8
Subtracting 6856 from 7290 leaves us with 434.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4340, and continue the process.

Moving on to step 10:
857 can be fit into 4340 5 times, resulting in a remainder of 55.
Record the quotient 5 as the next digit in the result. 
Result so far: 48304.85
If we subtract 4285 from 4340, we get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

On to step 11:
When dividing 550 by 857, we get 0 with a remainder of 550.
The next digit of our result is 0. 
Result so far: 48304.85
If we subtract 0 from 550, we get 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5500, and continue the process.

Step 12:
If we divide 5500 by 857, we get 6 and a remainder of 358.
Use 6 as the next digit of our solution. 
Result so far: 48304.8506
Subtracting 5142 from 5500 leaves us with 358.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3580, and continue the process.

Let's proceed to step 13:
857 goes into 3580 4 times with a remainder of 152.
Record the quotient 4 as the next digit in the result. 
Result so far: 48304.85064
Subtract 3428 from 3580 to get 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Going ahead to step 14:
If we divide 1520 by 857, we get 1 and a remainder of 663.
The number 1 becomes the next digit in our result. 
Result so far: 48304.850641
Deduct 857 from 1520 and we're left with 663.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6630, and continue the process.

Step 15:
6630 divided by 857 is 7 with a remainder of 631.
The next digit of our result is 7. 
Result so far: 48304.8506417
The remainder is 631 after subtracting 5999 from 6630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6310, and continue the process.

On to step 16:
857 goes into 6310 7 times with a remainder of 311.
Write down 7 as next digit of the result. 
Result so far: 48304.85064177
If we take 5999 away from 6310, we end up with 311.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3110, and continue the process.

The final outcome is 48304.85064177, with a leftover of 3.11e-07.
