We're dividing 87355006 by 839 
We're looking to find how many times 839 goes into 87355006.

On to step 1:
The number 839 fits into 8 0 times, leaving a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Bring next digit (7) of the dividend behind the 8 and repeat the process: 87 / 839

On to step 2:
The number 839 fits into 87 0 times, leaving a remainder of 87.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 87, we end up with 87.
Grab the next digit (3) from the dividend, add it to 87, then carry on: 873 / 839

Step 3:
873 divided by 839 is 1 with a remainder of 34.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 839 from 873 and we're left with 34.
Grab the next digit (5) from the dividend, add it to 34, then carry on: 345 / 839

Advancing to step 4:
839 goes into 345 0 times with a remainder of 345.
The next digit of our result is 0. 
Result so far: 10.0
Subtract 0 from 345 to get 345.
Include the next digit (5) from the dividend after 345, then repeat: 3455 / 839

Let's proceed to step 5:
3455 divided by 839 is 4 with a remainder of 99.
The next digit of our result is 4. 
Result so far: 104.0
If we subtract 3356 from 3455, we get 99.
Include the next digit (0) from the dividend after 99, then repeat: 990 / 839

Moving on to step 6:
When dividing 990 by 839, we get 1 with a remainder of 151.
The number 1 becomes the next digit in our result. 
Result so far: 1041.0
Subtract 839 from 990 to get 151.
Append the next digit (0) from the dividend to 151 and continue with: 1510 / 839

Advancing to step 7:
The number 839 fits into 1510 1 times, leaving a remainder of 671.
Put 1 as the next digit of the answer. 
Result so far: 10411.0
Deduct 839 from 1510 and we're left with 671.
Fetch the next digit (6) from the dividend, attach it to 671 and continue: 6716 / 839

Let's proceed to step 8:
6716 divided by 839 is 8 with a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 104118.0
If we take 6712 away from 6716, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 9:
The number 839 fits into 40 0 times, leaving a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 104118.0
Subtracting 0 from 40 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 10:
839 goes into 400 0 times with a remainder of 400.
Use 0 as the next digit of our solution. 
Result so far: 104118.0
If we subtract 0 from 400, we get 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

The final result is 104118.0 with a remainder of 0.4.
