99555098 ÷ 858 
We want to figure out the number of times 99555098 can be divided by 858.

Going ahead to step 1:
When dividing 9 by 858, we get 0 with a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Fetch the next digit (9) from the dividend, attach it to 9 and continue: 99 / 858

Moving on to step 2:
858 can be fit into 99 0 times, resulting in a remainder of 99.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 99 to get 99.
Include the next digit (5) from the dividend after 99, then repeat: 995 / 858

Going ahead to step 3:
995 divided by 858 is 1 with a remainder of 137.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 858 from 995, we get 137.
Grab the next digit (5) from the dividend, add it to 137, then carry on: 1375 / 858

Let's proceed to step 4:
858 can be fit into 1375 1 times, resulting in a remainder of 517.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
If we take 858 away from 1375, we end up with 517.
Grab the next digit (5) from the dividend, add it to 517, then carry on: 5175 / 858

Moving on to step 5:
858 goes into 5175 6 times with a remainder of 27.
The next digit of our result is 6. 
Result so far: 116.0
The remainder is 27 after subtracting 5148 from 5175.
Fetch the next digit (0) from the dividend, attach it to 27 and continue: 270 / 858

Let's proceed to step 6:
858 can be fit into 270 0 times, resulting in a remainder of 270.
The next digit of our result is 0. 
Result so far: 1160.0
The remainder is 270 after subtracting 0 from 270.
Take the next digit (9) from the dividend and append it to 270, then repeat: 2709 / 858

Step 7:
858 goes into 2709 3 times with a remainder of 135.
Write down 3 as next digit of the result. 
Result so far: 11603.0
Deduct 2574 from 2709 and we're left with 135.
Take the next digit (8) from the dividend and append it to 135, then repeat: 1358 / 858

On to step 8:
When dividing 1358 by 858, we get 1 with a remainder of 500.
Write down 1 as next digit of the result. 
Result so far: 116031.0
Subtracting 858 from 1358 leaves us with 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Going ahead to step 9:
The number 858 fits into 5000 5 times, leaving a remainder of 710.
Write down 5 as next digit of the result. 
Result so far: 116031.5
Subtract 4290 from 5000 to get 710.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7100, and continue the process.

Advancing to step 10:
When dividing 7100 by 858, we get 8 with a remainder of 236.
The next digit of our result is 8. 
Result so far: 116031.58
Deduct 6864 from 7100 and we're left with 236.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

Let's proceed to step 11:
If we divide 2360 by 858, we get 2 and a remainder of 644.
Record the quotient 2 as the next digit in the result. 
Result so far: 116031.582
Deduct 1716 from 2360 and we're left with 644.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6440, and continue the process.

Let's proceed to step 12:
If we divide 6440 by 858, we get 7 and a remainder of 434.
Record the quotient 7 as the next digit in the result. 
Result so far: 116031.5827
Deduct 6006 from 6440 and we're left with 434.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4340, and continue the process.

Advancing to step 13:
858 can be fit into 4340 5 times, resulting in a remainder of 50.
The number 5 becomes the next digit in our result. 
Result so far: 116031.58275
Deduct 4290 from 4340 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 14:
858 can be fit into 500 0 times, resulting in a remainder of 500.
The number 0 becomes the next digit in our result. 
Result so far: 116031.58275
The remainder is 500 after subtracting 0 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Going ahead to step 15:
858 can be fit into 5000 5 times, resulting in a remainder of 710.
Use 5 as the next digit of our solution. 
Result so far: 116031.5827505
Subtract 4290 from 5000 to get 710.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7100, and continue the process.

Going ahead to step 16:
If we divide 7100 by 858, we get 8 and a remainder of 236.
The next digit of our result is 8. 
Result so far: 116031.58275058
If we take 6864 away from 7100, we end up with 236.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

In conclusion, the division gives 116031.58275058 with a balance of 2.36e-07.
