We look at the division of 84578249 by 856 
We want to figure out the number of times 84578249 can be divided by 856.

Let's proceed to step 1:
When dividing 8 by 856, we get 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Bring next digit (4) of the dividend behind the 8 and repeat the process: 84 / 856

Let's proceed to step 2:
84 divided by 856 is 0 with a remainder of 84.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 84 after subtracting 0 from 84.
Grab the next digit (5) from the dividend, add it to 84, then carry on: 845 / 856

Advancing to step 3:
When dividing 845 by 856, we get 0 with a remainder of 845.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 845 and we're left with 845.
Take the next digit (7) from the dividend and append it to 845, then repeat: 8457 / 856

Step 4:
When dividing 8457 by 856, we get 9 with a remainder of 753.
Use 9 as the next digit of our solution. 
Result so far: 9.0
Subtract 7704 from 8457 to get 753.
Fetch the next digit (8) from the dividend, attach it to 753 and continue: 7538 / 856

Going ahead to step 5:
The number 856 fits into 7538 8 times, leaving a remainder of 690.
The number 8 becomes the next digit in our result. 
Result so far: 98.0
The remainder is 690 after subtracting 6848 from 7538.
Grab the next digit (2) from the dividend, add it to 690, then carry on: 6902 / 856

Moving on to step 6:
856 goes into 6902 8 times with a remainder of 54.
Use 8 as the next digit of our solution. 
Result so far: 988.0
Subtracting 6848 from 6902 leaves us with 54.
Include the next digit (4) from the dividend after 54, then repeat: 544 / 856

On to step 7:
When dividing 544 by 856, we get 0 with a remainder of 544.
Record the quotient 0 as the next digit in the result. 
Result so far: 9880.0
The remainder is 544 after subtracting 0 from 544.
Bring next digit (9) of the dividend behind the 544 and repeat the process: 5449 / 856

Moving on to step 8:
The number 856 fits into 5449 6 times, leaving a remainder of 313.
Put 6 as the next digit of the answer. 
Result so far: 98806.0
Subtracting 5136 from 5449 leaves us with 313.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3130, and continue the process.

Step 9:
3130 divided by 856 is 3 with a remainder of 562.
Use 3 as the next digit of our solution. 
Result so far: 98806.3
Deduct 2568 from 3130 and we're left with 562.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5620, and continue the process.

Let's proceed to step 10:
5620 divided by 856 is 6 with a remainder of 484.
Use 6 as the next digit of our solution. 
Result so far: 98806.36
Subtract 5136 from 5620 to get 484.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4840, and continue the process.

Let's proceed to step 11:
If we divide 4840 by 856, we get 5 and a remainder of 560.
The next digit of our result is 5. 
Result so far: 98806.365
Subtracting 4280 from 4840 leaves us with 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Moving on to step 12:
When dividing 5600 by 856, we get 6 with a remainder of 464.
The next digit of our result is 6. 
Result so far: 98806.3656
Subtract 5136 from 5600 to get 464.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4640, and continue the process.

Let's proceed to step 13:
4640 divided by 856 is 5 with a remainder of 360.
Write down 5 as next digit of the result. 
Result so far: 98806.36565
Subtracting 4280 from 4640 leaves us with 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Advancing to step 14:
856 can be fit into 3600 4 times, resulting in a remainder of 176.
The next digit of our result is 4. 
Result so far: 98806.365654
Subtract 3424 from 3600 to get 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

On to step 15:
The number 856 fits into 1760 2 times, leaving a remainder of 48.
The next digit of our result is 2. 
Result so far: 98806.3656542
The remainder is 48 after subtracting 1712 from 1760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 16:
The number 856 fits into 480 0 times, leaving a remainder of 480.
The number 0 becomes the next digit in our result. 
Result so far: 98806.3656542
Subtract 0 from 480 to get 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

The final outcome is 98806.3656542, with a leftover of 4.8e-07.
