99165703 ÷ 231 
We want to figure out the number of times 99165703 can be divided by 231.

On to step 1:
231 goes into 9 0 times with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Bring next digit (9) of the dividend behind the 9 and repeat the process: 99 / 231

Let's proceed to step 2:
99 divided by 231 is 0 with a remainder of 99.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 99 leaves us with 99.
Fetch the next digit (1) from the dividend, attach it to 99 and continue: 991 / 231

Moving on to step 3:
If we divide 991 by 231, we get 4 and a remainder of 67.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we take 924 away from 991, we end up with 67.
Grab the next digit (6) from the dividend, add it to 67, then carry on: 676 / 231

Let's proceed to step 4:
231 goes into 676 2 times with a remainder of 214.
Write down 2 as next digit of the result. 
Result so far: 42.0
Subtracting 462 from 676 leaves us with 214.
Take the next digit (5) from the dividend and append it to 214, then repeat: 2145 / 231

Let's proceed to step 5:
When dividing 2145 by 231, we get 9 with a remainder of 66.
Use 9 as the next digit of our solution. 
Result so far: 429.0
If we subtract 2079 from 2145, we get 66.
Bring next digit (7) of the dividend behind the 66 and repeat the process: 667 / 231

Step 6:
231 can be fit into 667 2 times, resulting in a remainder of 205.
The next digit of our result is 2. 
Result so far: 4292.0
The remainder is 205 after subtracting 462 from 667.
Take the next digit (0) from the dividend and append it to 205, then repeat: 2050 / 231

Let's proceed to step 7:
If we divide 2050 by 231, we get 8 and a remainder of 202.
Use 8 as the next digit of our solution. 
Result so far: 42928.0
Subtracting 1848 from 2050 leaves us with 202.
Fetch the next digit (3) from the dividend, attach it to 202 and continue: 2023 / 231

Let's proceed to step 8:
2023 divided by 231 is 8 with a remainder of 175.
Put 8 as the next digit of the answer. 
Result so far: 429288.0
If we take 1848 away from 2023, we end up with 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

Moving on to step 9:
231 can be fit into 1750 7 times, resulting in a remainder of 133.
Put 7 as the next digit of the answer. 
Result so far: 429288.7
Deduct 1617 from 1750 and we're left with 133.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1330, and continue the process.

Going ahead to step 10:
231 can be fit into 1330 5 times, resulting in a remainder of 175.
Use 5 as the next digit of our solution. 
Result so far: 429288.75
If we take 1155 away from 1330, we end up with 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

On to step 11:
When dividing 1750 by 231, we get 7 with a remainder of 133.
Put 7 as the next digit of the answer. 
Result so far: 429288.757
Subtract 1617 from 1750 to get 133.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1330, and continue the process.

Let's proceed to step 12:
231 can be fit into 1330 5 times, resulting in a remainder of 175.
Use 5 as the next digit of our solution. 
Result so far: 429288.7575
If we subtract 1155 from 1330, we get 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

On to step 13:
231 can be fit into 1750 7 times, resulting in a remainder of 133.
The number 7 becomes the next digit in our result. 
Result so far: 429288.75757
If we subtract 1617 from 1750, we get 133.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1330, and continue the process.

Step 14:
1330 divided by 231 is 5 with a remainder of 175.
Write down 5 as next digit of the result. 
Result so far: 429288.757575
Subtract 1155 from 1330 to get 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

Advancing to step 15:
1750 divided by 231 is 7 with a remainder of 133.
Use 7 as the next digit of our solution. 
Result so far: 429288.7575757
Subtracting 1617 from 1750 leaves us with 133.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1330, and continue the process.

Going ahead to step 16:
1330 divided by 231 is 5 with a remainder of 175.
Record the quotient 5 as the next digit in the result. 
Result so far: 429288.75757575
If we subtract 1155 from 1330, we get 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

The final outcome is 429288.75757575, with a leftover of 1.75e-07.
