We look at the division of 18443405 by 857 
We're looking to find how many times 857 goes into 18443405.

Moving on to step 1:
The number 857 fits into 1 0 times, leaving a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Take the next digit (8) from the dividend and append it to 1, then repeat: 18 / 857

Let's proceed to step 2:
18 divided by 857 is 0 with a remainder of 18.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 18 to get 18.
Take the next digit (4) from the dividend and append it to 18, then repeat: 184 / 857

On to step 3:
857 goes into 184 0 times with a remainder of 184.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 184, we get 184.
Fetch the next digit (4) from the dividend, attach it to 184 and continue: 1844 / 857

Moving on to step 4:
857 goes into 1844 2 times with a remainder of 130.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we take 1714 away from 1844, we end up with 130.
Bring next digit (3) of the dividend behind the 130 and repeat the process: 1303 / 857

Advancing to step 5:
If we divide 1303 by 857, we get 1 and a remainder of 446.
Record the quotient 1 as the next digit in the result. 
Result so far: 21.0
If we subtract 857 from 1303, we get 446.
Fetch the next digit (4) from the dividend, attach it to 446 and continue: 4464 / 857

On to step 6:
857 goes into 4464 5 times with a remainder of 179.
The next digit of our result is 5. 
Result so far: 215.0
Deduct 4285 from 4464 and we're left with 179.
Append the next digit (0) from the dividend to 179 and continue with: 1790 / 857

Step 7:
The number 857 fits into 1790 2 times, leaving a remainder of 76.
Write down 2 as next digit of the result. 
Result so far: 2152.0
The remainder is 76 after subtracting 1714 from 1790.
Bring next digit (5) of the dividend behind the 76 and repeat the process: 765 / 857

Let's proceed to step 8:
765 divided by 857 is 0 with a remainder of 765.
Put 0 as the next digit of the answer. 
Result so far: 21520.0
Subtracting 0 from 765 leaves us with 765.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7650, and continue the process.

Advancing to step 9:
7650 divided by 857 is 8 with a remainder of 794.
Record the quotient 8 as the next digit in the result. 
Result so far: 21520.8
If we take 6856 away from 7650, we end up with 794.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7940, and continue the process.

Let's proceed to step 10:
7940 divided by 857 is 9 with a remainder of 227.
Record the quotient 9 as the next digit in the result. 
Result so far: 21520.89
Subtracting 7713 from 7940 leaves us with 227.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2270, and continue the process.

Let's proceed to step 11:
When dividing 2270 by 857, we get 2 with a remainder of 556.
The next digit of our result is 2. 
Result so far: 21520.892
If we take 1714 away from 2270, we end up with 556.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5560, and continue the process.

Moving on to step 12:
If we divide 5560 by 857, we get 6 and a remainder of 418.
The next digit of our result is 6. 
Result so far: 21520.8926
The remainder is 418 after subtracting 5142 from 5560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4180, and continue the process.

Step 13:
The number 857 fits into 4180 4 times, leaving a remainder of 752.
The number 4 becomes the next digit in our result. 
Result so far: 21520.89264
If we take 3428 away from 4180, we end up with 752.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7520, and continue the process.

Moving on to step 14:
7520 divided by 857 is 8 with a remainder of 664.
Use 8 as the next digit of our solution. 
Result so far: 21520.892648
Deduct 6856 from 7520 and we're left with 664.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6640, and continue the process.

Moving on to step 15:
If we divide 6640 by 857, we get 7 and a remainder of 641.
Record the quotient 7 as the next digit in the result. 
Result so far: 21520.8926487
If we subtract 5999 from 6640, we get 641.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6410, and continue the process.

Step 16:
When dividing 6410 by 857, we get 7 with a remainder of 411.
Write down 7 as next digit of the result. 
Result so far: 21520.89264877
Deduct 5999 from 6410 and we're left with 411.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4110, and continue the process.

After the division, we end up with 21520.89264877 and a remainder of 4.11e-07.
