96810099 divided by 158 
We want to figure out the number of times 96810099 can be divided by 158.

Step 1:
158 can be fit into 9 0 times, resulting in a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Grab the next digit (6) from the dividend, add it to 9, then carry on: 96 / 158

Moving on to step 2:
The number 158 fits into 96 0 times, leaving a remainder of 96.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 96 and we're left with 96.
Take the next digit (8) from the dividend and append it to 96, then repeat: 968 / 158

Advancing to step 3:
If we divide 968 by 158, we get 6 and a remainder of 20.
The next digit of our result is 6. 
Result so far: 6.0
The remainder is 20 after subtracting 948 from 968.
Bring next digit (1) of the dividend behind the 20 and repeat the process: 201 / 158

Let's proceed to step 4:
158 can be fit into 201 1 times, resulting in a remainder of 43.
Use 1 as the next digit of our solution. 
Result so far: 61.0
Subtract 158 from 201 to get 43.
Fetch the next digit (0) from the dividend, attach it to 43 and continue: 430 / 158

On to step 5:
430 divided by 158 is 2 with a remainder of 114.
Record the quotient 2 as the next digit in the result. 
Result so far: 612.0
The remainder is 114 after subtracting 316 from 430.
Include the next digit (0) from the dividend after 114, then repeat: 1140 / 158

Moving on to step 6:
If we divide 1140 by 158, we get 7 and a remainder of 34.
Use 7 as the next digit of our solution. 
Result so far: 6127.0
Subtracting 1106 from 1140 leaves us with 34.
Append the next digit (9) from the dividend to 34 and continue with: 349 / 158

Going ahead to step 7:
When dividing 349 by 158, we get 2 with a remainder of 33.
Write down 2 as next digit of the result. 
Result so far: 61272.0
If we take 316 away from 349, we end up with 33.
Fetch the next digit (9) from the dividend, attach it to 33 and continue: 339 / 158

Going ahead to step 8:
339 divided by 158 is 2 with a remainder of 23.
The next digit of our result is 2. 
Result so far: 612722.0
Subtracting 316 from 339 leaves us with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Let's proceed to step 9:
If we divide 230 by 158, we get 1 and a remainder of 72.
Use 1 as the next digit of our solution. 
Result so far: 612722.1
The remainder is 72 after subtracting 158 from 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Let's proceed to step 10:
158 can be fit into 720 4 times, resulting in a remainder of 88.
The next digit of our result is 4. 
Result so far: 612722.14
If we subtract 632 from 720, we get 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Advancing to step 11:
158 can be fit into 880 5 times, resulting in a remainder of 90.
The next digit of our result is 5. 
Result so far: 612722.145
If we subtract 790 from 880, 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.

Advancing to step 12:
900 divided by 158 is 5 with a remainder of 110.
Put 5 as the next digit of the answer. 
Result so far: 612722.1455
Deduct 790 from 900 and we're left with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Our division results in 612722.1455 with a remaining 0.0011.
