We look at the division of 84399536 by 837 
We want to divide 84399536 by 837.

Step 1:
The number 837 fits into 8 0 times, leaving a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Include the next digit (4) from the dividend after 8, then repeat: 84 / 837

Moving on to step 2:
84 divided by 837 is 0 with a remainder of 84.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 84 and we're left with 84.
Take the next digit (3) from the dividend and append it to 84, then repeat: 843 / 837

Moving on to step 3:
When dividing 843 by 837, we get 1 with a remainder of 6.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 837 from 843, we get 6.
Fetch the next digit (9) from the dividend, attach it to 6 and continue: 69 / 837

Let's proceed to step 4:
The number 837 fits into 69 0 times, leaving a remainder of 69.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
The remainder is 69 after subtracting 0 from 69.
Bring next digit (9) of the dividend behind the 69 and repeat the process: 699 / 837

Advancing to step 5:
699 divided by 837 is 0 with a remainder of 699.
Record the quotient 0 as the next digit in the result. 
Result so far: 100.0
Subtract 0 from 699 to get 699.
Take the next digit (5) from the dividend and append it to 699, then repeat: 6995 / 837

Advancing to step 6:
837 goes into 6995 8 times with a remainder of 299.
Write down 8 as next digit of the result. 
Result so far: 1008.0
Deduct 6696 from 6995 and we're left with 299.
Append the next digit (3) from the dividend to 299 and continue with: 2993 / 837

Let's proceed to step 7:
The number 837 fits into 2993 3 times, leaving a remainder of 482.
Write down 3 as next digit of the result. 
Result so far: 10083.0
If we take 2511 away from 2993, we end up with 482.
Grab the next digit (6) from the dividend, add it to 482, then carry on: 4826 / 837

Moving on to step 8:
When dividing 4826 by 837, we get 5 with a remainder of 641.
Put 5 as the next digit of the answer. 
Result so far: 100835.0
Deduct 4185 from 4826 and we're left with 641.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6410, and continue the process.

On to step 9:
If we divide 6410 by 837, we get 7 and a remainder of 551.
The number 7 becomes the next digit in our result. 
Result so far: 100835.7
Subtracting 5859 from 6410 leaves us with 551.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5510, and continue the process.

Step 10:
The number 837 fits into 5510 6 times, leaving a remainder of 488.
Use 6 as the next digit of our solution. 
Result so far: 100835.76
If we take 5022 away from 5510, we end up with 488.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4880, and continue the process.

On to step 11:
837 can be fit into 4880 5 times, resulting in a remainder of 695.
Record the quotient 5 as the next digit in the result. 
Result so far: 100835.765
Deduct 4185 from 4880 and we're left with 695.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6950, and continue the process.

Step 12:
6950 divided by 837 is 8 with a remainder of 254.
Write down 8 as next digit of the result. 
Result so far: 100835.7658
The remainder is 254 after subtracting 6696 from 6950.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2540, and continue the process.

Advancing to step 13:
2540 divided by 837 is 3 with a remainder of 29.
Record the quotient 3 as the next digit in the result. 
Result so far: 100835.76583
The remainder is 29 after subtracting 2511 from 2540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Advancing to step 14:
When dividing 290 by 837, we get 0 with a remainder of 290.
Put 0 as the next digit of the answer. 
Result so far: 100835.76583
The remainder is 290 after subtracting 0 from 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

Let's proceed to step 15:
837 can be fit into 2900 3 times, resulting in a remainder of 389.
Record the quotient 3 as the next digit in the result. 
Result so far: 100835.7658303
Subtracting 2511 from 2900 leaves us with 389.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3890, and continue the process.

Advancing to step 16:
If we divide 3890 by 837, we get 4 and a remainder of 542.
The next digit of our result is 4. 
Result so far: 100835.76583034
Subtract 3348 from 3890 to get 542.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5420, and continue the process.

The final outcome is 100835.76583034, with a leftover of 5.42e-07.
