851857 divided by 19 
We want to divide 851857 by 19.

Advancing to step 1:
8 divided by 19 is 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Append the next digit (5) from the dividend to 8 and continue with: 85 / 19

Advancing to step 2:
When dividing 85 by 19, we get 4 with a remainder of 9.
Write down 4 as next digit of the result. 
Result so far: 4.0
The remainder is 9 after subtracting 76 from 85.
Include the next digit (1) from the dividend after 9, then repeat: 91 / 19

Moving on to step 3:
19 goes into 91 4 times with a remainder of 15.
Put 4 as the next digit of the answer. 
Result so far: 44.0
Subtract 76 from 91 to get 15.
Grab the next digit (8) from the dividend, add it to 15, then carry on: 158 / 19

Let's proceed to step 4:
If we divide 158 by 19, we get 8 and a remainder of 6.
Put 8 as the next digit of the answer. 
Result so far: 448.0
Deduct 152 from 158 and we're left with 6.
Bring next digit (5) of the dividend behind the 6 and repeat the process: 65 / 19

Moving on to step 5:
When dividing 65 by 19, we get 3 with a remainder of 8.
Use 3 as the next digit of our solution. 
Result so far: 4483.0
If we take 57 away from 65, we end up with 8.
Grab the next digit (7) from the dividend, add it to 8, then carry on: 87 / 19

Advancing to step 6:
19 goes into 87 4 times with a remainder of 11.
Record the quotient 4 as the next digit in the result. 
Result so far: 44834.0
Deduct 76 from 87 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 7:
19 can be fit into 110 5 times, resulting in a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 44834.5
Subtracting 95 from 110 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 8:
150 divided by 19 is 7 with a remainder of 17.
The number 7 becomes the next digit in our result. 
Result so far: 44834.57
Subtract 133 from 150 to get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

On to step 9:
If we divide 170 by 19, we get 8 and a remainder of 18.
Write down 8 as next digit of the result. 
Result so far: 44834.578
The remainder is 18 after subtracting 152 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 10:
180 divided by 19 is 9 with a remainder of 9.
The next digit of our result is 9. 
Result so far: 44834.5789
Deduct 171 from 180 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 11:
90 divided by 19 is 4 with a remainder of 14.
Record the quotient 4 as the next digit in the result. 
Result so far: 44834.57894
If we subtract 76 from 90, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 12:
If we divide 140 by 19, we get 7 and a remainder of 7.
Write down 7 as next digit of the result. 
Result so far: 44834.578947
Deduct 133 from 140 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 13:
If we divide 70 by 19, we get 3 and a remainder of 13.
Write down 3 as next digit of the result. 
Result so far: 44834.5789473
If we take 57 away from 70, we end up with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Advancing to step 14:
The number 19 fits into 130 6 times, leaving a remainder of 16.
The number 6 becomes the next digit in our result. 
Result so far: 44834.57894736
Deduct 114 from 130 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

After the division, we end up with 44834.57894736 and a remainder of 1.6e-08.
