18685879 ÷ 837 
Let's see how many times 837 fits into 18685879.

Moving on to step 1:
837 can be fit into 1 0 times, resulting in a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Append the next digit (8) from the dividend to 1 and continue with: 18 / 837

Advancing to step 2:
837 goes into 18 0 times with a remainder of 18.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 18 and we're left with 18.
Fetch the next digit (6) from the dividend, attach it to 18 and continue: 186 / 837

Let's proceed to step 3:
When dividing 186 by 837, we get 0 with a remainder of 186.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 186 and we're left with 186.
Take the next digit (8) from the dividend and append it to 186, then repeat: 1868 / 837

Let's proceed to step 4:
The number 837 fits into 1868 2 times, leaving a remainder of 194.
Put 2 as the next digit of the answer. 
Result so far: 2.0
The remainder is 194 after subtracting 1674 from 1868.
Include the next digit (5) from the dividend after 194, then repeat: 1945 / 837

Going ahead to step 5:
When dividing 1945 by 837, we get 2 with a remainder of 271.
Use 2 as the next digit of our solution. 
Result so far: 22.0
Subtract 1674 from 1945 to get 271.
Grab the next digit (8) from the dividend, add it to 271, then carry on: 2718 / 837

On to step 6:
When dividing 2718 by 837, we get 3 with a remainder of 207.
Write down 3 as next digit of the result. 
Result so far: 223.0
If we take 2511 away from 2718, we end up with 207.
Grab the next digit (7) from the dividend, add it to 207, then carry on: 2077 / 837

Step 7:
When dividing 2077 by 837, we get 2 with a remainder of 403.
Write down 2 as next digit of the result. 
Result so far: 2232.0
Subtracting 1674 from 2077 leaves us with 403.
Fetch the next digit (9) from the dividend, attach it to 403 and continue: 4039 / 837

On to step 8:
4039 divided by 837 is 4 with a remainder of 691.
Use 4 as the next digit of our solution. 
Result so far: 22324.0
The remainder is 691 after subtracting 3348 from 4039.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6910, and continue the process.

Going ahead to step 9:
837 goes into 6910 8 times with a remainder of 214.
Write down 8 as next digit of the result. 
Result so far: 22324.8
Deduct 6696 from 6910 and we're left with 214.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2140, and continue the process.

Step 10:
When dividing 2140 by 837, we get 2 with a remainder of 466.
Write down 2 as next digit of the result. 
Result so far: 22324.82
If we take 1674 away from 2140, we end up with 466.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4660, and continue the process.

Let's proceed to step 11:
4660 divided by 837 is 5 with a remainder of 475.
The next digit of our result is 5. 
Result so far: 22324.825
The remainder is 475 after subtracting 4185 from 4660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4750, and continue the process.

Going ahead to step 12:
837 can be fit into 4750 5 times, resulting in a remainder of 565.
Write down 5 as next digit of the result. 
Result so far: 22324.8255
Deduct 4185 from 4750 and we're left with 565.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5650, and continue the process.

After the division, we end up with 22324.8255 and a remainder of 0.00565.
