We're dividing 15375858 by 857 
Let's see how many times 857 fits into 15375858.

Moving on to step 1:
1 divided by 857 is 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Include the next digit (5) from the dividend after 1, then repeat: 15 / 857

Let's proceed to step 2:
857 goes into 15 0 times with a remainder of 15.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 15 after subtracting 0 from 15.
Fetch the next digit (3) from the dividend, attach it to 15 and continue: 153 / 857

Step 3:
The number 857 fits into 153 0 times, leaving a remainder of 153.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 153 after subtracting 0 from 153.
Bring next digit (7) of the dividend behind the 153 and repeat the process: 1537 / 857

Moving on to step 4:
When dividing 1537 by 857, we get 1 with a remainder of 680.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 680 after subtracting 857 from 1537.
Include the next digit (5) from the dividend after 680, then repeat: 6805 / 857

Going ahead to step 5:
857 goes into 6805 7 times with a remainder of 806.
Put 7 as the next digit of the answer. 
Result so far: 17.0
The remainder is 806 after subtracting 5999 from 6805.
Take the next digit (8) from the dividend and append it to 806, then repeat: 8068 / 857

Going ahead to step 6:
857 goes into 8068 9 times with a remainder of 355.
The number 9 becomes the next digit in our result. 
Result so far: 179.0
Subtract 7713 from 8068 to get 355.
Grab the next digit (5) from the dividend, add it to 355, then carry on: 3555 / 857

Advancing to step 7:
857 goes into 3555 4 times with a remainder of 127.
The number 4 becomes the next digit in our result. 
Result so far: 1794.0
If we take 3428 away from 3555, we end up with 127.
Append the next digit (8) from the dividend to 127 and continue with: 1278 / 857

Going ahead to step 8:
The number 857 fits into 1278 1 times, leaving a remainder of 421.
Put 1 as the next digit of the answer. 
Result so far: 17941.0
Deduct 857 from 1278 and we're left with 421.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4210, and continue the process.

On to step 9:
If we divide 4210 by 857, we get 4 and a remainder of 782.
Use 4 as the next digit of our solution. 
Result so far: 17941.4
The remainder is 782 after subtracting 3428 from 4210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7820, and continue the process.

Moving on to step 10:
If we divide 7820 by 857, we get 9 and a remainder of 107.
Record the quotient 9 as the next digit in the result. 
Result so far: 17941.49
Deduct 7713 from 7820 and we're left 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.

Let's proceed to step 11:
857 can be fit into 1070 1 times, resulting in a remainder of 213.
Put 1 as the next digit of the answer. 
Result so far: 17941.491
Subtracting 857 from 1070 leaves us with 213.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2130, and continue the process.

On to step 12:
The number 857 fits into 2130 2 times, leaving a remainder of 416.
Record the quotient 2 as the next digit in the result. 
Result so far: 17941.4912
The remainder is 416 after subtracting 1714 from 2130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

Going ahead to step 13:
When dividing 4160 by 857, we get 4 with a remainder of 732.
Put 4 as the next digit of the answer. 
Result so far: 17941.49124
If we subtract 3428 from 4160, we get 732.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7320, and continue the process.

On to step 14:
If we divide 7320 by 857, we get 8 and a remainder of 464.
Use 8 as the next digit of our solution. 
Result so far: 17941.491248
Deduct 6856 from 7320 and we're left with 464.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4640, and continue the process.

Advancing to step 15:
If we divide 4640 by 857, we get 5 and a remainder of 355.
Record the quotient 5 as the next digit in the result. 
Result so far: 17941.4912485
If we subtract 4285 from 4640, we get 355.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3550, and continue the process.

Let's proceed to step 16:
857 goes into 3550 4 times with a remainder of 122.
Put 4 as the next digit of the answer. 
Result so far: 17941.49124854
If we subtract 3428 from 3550, we get 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

In conclusion, the division gives 17941.49124854 with a balance of 1.22e-07.
