98506858 ÷ 878 
We want to figure out the number of times 98506858 can be divided by 878.

On to step 1:
9 divided by 878 is 0 with a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Bring next digit (8) of the dividend behind the 9 and repeat the process: 98 / 878

Going ahead to step 2:
878 can be fit into 98 0 times, resulting in a remainder of 98.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 98 leaves us with 98.
Grab the next digit (5) from the dividend, add it to 98, then carry on: 985 / 878

Moving on to step 3:
If we divide 985 by 878, we get 1 and a remainder of 107.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 107 after subtracting 878 from 985.
Append the next digit (0) from the dividend to 107 and continue with: 1070 / 878

Let's proceed to step 4:
878 goes into 1070 1 times with a remainder of 192.
Put 1 as the next digit of the answer. 
Result so far: 11.0
The remainder is 192 after subtracting 878 from 1070.
Bring next digit (6) of the dividend behind the 192 and repeat the process: 1926 / 878

Going ahead to step 5:
If we divide 1926 by 878, we get 2 and a remainder of 170.
The next digit of our result is 2. 
Result so far: 112.0
Subtract 1756 from 1926 to get 170.
Include the next digit (8) from the dividend after 170, then repeat: 1708 / 878

Let's proceed to step 6:
If we divide 1708 by 878, we get 1 and a remainder of 830.
The next digit of our result is 1. 
Result so far: 1121.0
Subtracting 878 from 1708 leaves us with 830.
Take the next digit (5) from the dividend and append it to 830, then repeat: 8305 / 878

Let's proceed to step 7:
878 goes into 8305 9 times with a remainder of 403.
Put 9 as the next digit of the answer. 
Result so far: 11219.0
If we subtract 7902 from 8305, we get 403.
Take the next digit (8) from the dividend and append it to 403, then repeat: 4038 / 878

Going ahead to step 8:
The number 878 fits into 4038 4 times, leaving a remainder of 526.
Use 4 as the next digit of our solution. 
Result so far: 112194.0
If we subtract 3512 from 4038, we get 526.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5260, and continue the process.

Moving on to step 9:
The number 878 fits into 5260 5 times, leaving a remainder of 870.
The number 5 becomes the next digit in our result. 
Result so far: 112194.5
If we take 4390 away from 5260, we end up with 870.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8700, and continue the process.

Advancing to step 10:
The number 878 fits into 8700 9 times, leaving a remainder of 798.
Put 9 as the next digit of the answer. 
Result so far: 112194.59
The remainder is 798 after subtracting 7902 from 8700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7980, and continue the process.

Let's proceed to step 11:
7980 divided by 878 is 9 with a remainder of 78.
Record the quotient 9 as the next digit in the result. 
Result so far: 112194.599
The remainder is 78 after subtracting 7902 from 7980.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

The final outcome is 112194.599, with a leftover of 0.0078.
