Let's divide 74684191 by 839
We want to figure out the number of times 74684191 can be divided by 839.

On to step 1:
839 can be fit into 7 0 times, resulting in a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Bring next digit (4) of the dividend behind the 7 and repeat the process: 74 / 839

Advancing to step 2:
74 divided by 839 is 0 with a remainder of 74.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 74, we end up with 74.
Take the next digit (6) from the dividend and append it to 74, then repeat: 746 / 839

Going ahead to step 3:
839 goes into 746 0 times with a remainder of 746.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 746 after subtracting 0 from 746.
Fetch the next digit (8) from the dividend, attach it to 746 and continue: 7468 / 839

On to step 4:
If we divide 7468 by 839, we get 8 and a remainder of 756.
Write down 8 as next digit of the result. 
Result so far: 8.0
The remainder is 756 after subtracting 6712 from 7468.
Append the next digit (4) from the dividend to 756 and continue with: 7564 / 839

Advancing to step 5:
The number 839 fits into 7564 9 times, leaving a remainder of 13.
Use 9 as the next digit of our solution. 
Result so far: 89.0
The remainder is 13 after subtracting 7551 from 7564.
Take the next digit (1) from the dividend and append it to 13, then repeat: 131 / 839

Let's proceed to step 6:
If we divide 131 by 839, we get 0 and a remainder of 131.
The number 0 becomes the next digit in our result. 
Result so far: 890.0
Deduct 0 from 131 and we're left with 131.
Take the next digit (9) from the dividend and append it to 131, then repeat: 1319 / 839

On to step 7:
1319 divided by 839 is 1 with a remainder of 480.
Use 1 as the next digit of our solution. 
Result so far: 8901.0
If we subtract 839 from 1319, we get 480.
Append the next digit (1) from the dividend to 480 and continue with: 4801 / 839

Moving on to step 8:
When dividing 4801 by 839, we get 5 with a remainder of 606.
The next digit of our result is 5. 
Result so far: 89015.0
Deduct 4195 from 4801 and we're left with 606.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6060, and continue the process.

Let's proceed to step 9:
If we divide 6060 by 839, we get 7 and a remainder of 187.
Put 7 as the next digit of the answer. 
Result so far: 89015.7
Deduct 5873 from 6060 and we're left with 187.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1870, and continue the process.

Step 10:
1870 divided by 839 is 2 with a remainder of 192.
Put 2 as the next digit of the answer. 
Result so far: 89015.72
If we subtract 1678 from 1870, we get 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Let's proceed to step 11:
The number 839 fits into 1920 2 times, leaving a remainder of 242.
The number 2 becomes the next digit in our result. 
Result so far: 89015.722
The remainder is 242 after subtracting 1678 from 1920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2420, and continue the process.

After the division, we end up with 89015.722 and a remainder of 0.0242.
