854379 ÷ 99 
We're looking to find how many times 99 goes into 854379.

Advancing to step 1:
When dividing 8 by 99, we get 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Take the next digit (5) from the dividend and append it to 8, then repeat: 85 / 99

Moving on to step 2:
The number 99 fits into 85 0 times, leaving a remainder of 85.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 85, we get 85.
Bring next digit (4) of the dividend behind the 85 and repeat the process: 854 / 99

Going ahead to step 3:
99 goes into 854 8 times with a remainder of 62.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
The remainder is 62 after subtracting 792 from 854.
Grab the next digit (3) from the dividend, add it to 62, then carry on: 623 / 99

Moving on to step 4:
If we divide 623 by 99, we get 6 and a remainder of 29.
Record the quotient 6 as the next digit in the result. 
Result so far: 86.0
The remainder is 29 after subtracting 594 from 623.
Grab the next digit (7) from the dividend, add it to 29, then carry on: 297 / 99

Going ahead to step 5:
The number 99 fits into 297 3 times, leaving a remainder of 0.
The next digit of our result is 3. 
Result so far: 863.0
The remainder is 0 after subtracting 297 from 297.
Append the next digit (9) from the dividend to 0 and continue with: 9 / 99

Advancing to step 6:
If we divide 9 by 99, we get 0 and a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 8630.0
If we subtract 0 from 9, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 7:
90 divided by 99 is 0 with a remainder of 90.
Use 0 as the next digit of our solution. 
Result so far: 8630.0
Subtracting 0 from 90 leaves us with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Going ahead to step 8:
99 can be fit into 900 9 times, resulting in a remainder of 9.
Put 9 as the next digit of the answer. 
Result so far: 8630.09
Subtracting 891 from 900 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 9:
When dividing 90 by 99, we get 0 with a remainder of 90.
Write down 0 as next digit of the result. 
Result so far: 8630.09
The remainder is 90 after subtracting 0 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Going ahead to step 10:
If we divide 900 by 99, we get 9 and a remainder of 9.
The next digit of our result is 9. 
Result so far: 8630.0909
Subtract 891 from 900 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 11:
When dividing 90 by 99, we get 0 with a remainder of 90.
Put 0 as the next digit of the answer. 
Result so far: 8630.0909
Deduct 0 from 90 and we're left with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Advancing to step 12:
When dividing 900 by 99, we get 9 with a remainder of 9.
Use 9 as the next digit of our solution. 
Result so far: 8630.090909
Subtract 891 from 900 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 13:
When dividing 90 by 99, we get 0 with a remainder of 90.
Write down 0 as next digit of the result. 
Result so far: 8630.090909
If we subtract 0 from 90, we get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Going ahead to step 14:
If we divide 900 by 99, we get 9 and a remainder of 9.
Put 9 as the next digit of the answer. 
Result so far: 8630.09090909
The remainder is 9 after subtracting 891 from 900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

In conclusion, the division gives 8630.09090909 with a balance of 9e-09.
