Let's divide 19843879 by 851
We want to figure out the number of times 19843879 can be divided by 851.

Going ahead to step 1:
When dividing 1 by 851, we get 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Fetch the next digit (9) from the dividend, attach it to 1 and continue: 19 / 851

Advancing to step 2:
19 divided by 851 is 0 with a remainder of 19.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 19 and we're left with 19.
Append the next digit (8) from the dividend to 19 and continue with: 198 / 851

Step 3:
198 divided by 851 is 0 with a remainder of 198.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 198 after subtracting 0 from 198.
Bring next digit (4) of the dividend behind the 198 and repeat the process: 1984 / 851

Let's proceed to step 4:
1984 divided by 851 is 2 with a remainder of 282.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Deduct 1702 from 1984 and we're left with 282.
Include the next digit (3) from the dividend after 282, then repeat: 2823 / 851

On to step 5:
851 can be fit into 2823 3 times, resulting in a remainder of 270.
The next digit of our result is 3. 
Result so far: 23.0
If we take 2553 away from 2823, we end up with 270.
Grab the next digit (8) from the dividend, add it to 270, then carry on: 2708 / 851

On to step 6:
851 can be fit into 2708 3 times, resulting in a remainder of 155.
The next digit of our result is 3. 
Result so far: 233.0
If we take 2553 away from 2708, we end up with 155.
Append the next digit (7) from the dividend to 155 and continue with: 1557 / 851

Advancing to step 7:
851 can be fit into 1557 1 times, resulting in a remainder of 706.
The next digit of our result is 1. 
Result so far: 2331.0
Subtract 851 from 1557 to get 706.
Grab the next digit (9) from the dividend, add it to 706, then carry on: 7069 / 851

Going ahead to step 8:
851 can be fit into 7069 8 times, resulting in a remainder of 261.
Put 8 as the next digit of the answer. 
Result so far: 23318.0
If we take 6808 away from 7069, we end up with 261.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2610, and continue the process.

Step 9:
851 goes into 2610 3 times with a remainder of 57.
Write down 3 as next digit of the result. 
Result so far: 23318.3
Deduct 2553 from 2610 and we're left with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Let's proceed to step 10:
851 goes into 570 0 times with a remainder of 570.
Put 0 as the next digit of the answer. 
Result so far: 23318.3
If we take 0 away from 570, we end up with 570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5700, and continue the process.

Going ahead to step 11:
851 can be fit into 5700 6 times, resulting in a remainder of 594.
Write down 6 as next digit of the result. 
Result so far: 23318.306
Subtracting 5106 from 5700 leaves us with 594.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5940, and continue the process.

Step 12:
When dividing 5940 by 851, we get 6 with a remainder of 834.
The next digit of our result is 6. 
Result so far: 23318.3066
If we take 5106 away from 5940, we end up with 834.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8340, and continue the process.

The quotient of the division is 23318.3066, and the remainder is 0.00834.
