18617231 ÷ 158 
We want to figure out the number of times 18617231 can be divided by 158.

Let's proceed to step 1:
1 divided by 158 is 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Append the next digit (8) from the dividend to 1 and continue with: 18 / 158

Let's proceed to step 2:
158 goes into 18 0 times with a remainder of 18.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 18, we end up with 18.
Fetch the next digit (6) from the dividend, attach it to 18 and continue: 186 / 158

Going ahead to step 3:
The number 158 fits into 186 1 times, leaving a remainder of 28.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 158 from 186 and we're left with 28.
Take the next digit (1) from the dividend and append it to 28, then repeat: 281 / 158

On to step 4:
When dividing 281 by 158, we get 1 with a remainder of 123.
Write down 1 as next digit of the result. 
Result so far: 11.0
The remainder is 123 after subtracting 158 from 281.
Fetch the next digit (7) from the dividend, attach it to 123 and continue: 1237 / 158

Step 5:
When dividing 1237 by 158, we get 7 with a remainder of 131.
Record the quotient 7 as the next digit in the result. 
Result so far: 117.0
If we take 1106 away from 1237, we end up with 131.
Include the next digit (2) from the dividend after 131, then repeat: 1312 / 158

Step 6:
1312 divided by 158 is 8 with a remainder of 48.
The next digit of our result is 8. 
Result so far: 1178.0
If we subtract 1264 from 1312, we get 48.
Include the next digit (3) from the dividend after 48, then repeat: 483 / 158

Going ahead to step 7:
158 goes into 483 3 times with a remainder of 9.
The next digit of our result is 3. 
Result so far: 11783.0
The remainder is 9 after subtracting 474 from 483.
Fetch the next digit (1) from the dividend, attach it to 9 and continue: 91 / 158

Going ahead to step 8:
158 goes into 91 0 times with a remainder of 91.
The next digit of our result is 0. 
Result so far: 117830.0
Deduct 0 from 91 and we're left with 91.
Since there are no more digits in the dividend, we add a zero to the remainder making it 910, and continue the process.

Moving on to step 9:
When dividing 910 by 158, we get 5 with a remainder of 120.
Record the quotient 5 as the next digit in the result. 
Result so far: 117830.5
If we take 790 away from 910, we end up with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Let's proceed to step 10:
158 can be fit into 1200 7 times, resulting in a remainder of 94.
Use 7 as the next digit of our solution. 
Result so far: 117830.57
Subtracting 1106 from 1200 leaves us with 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Moving on to step 11:
When dividing 940 by 158, we get 5 with a remainder of 150.
Use 5 as the next digit of our solution. 
Result so far: 117830.575
If we take 790 away from 940, we end up with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

On to step 12:
1500 divided by 158 is 9 with a remainder of 78.
The next digit of our result is 9. 
Result so far: 117830.5759
If we subtract 1422 from 1500, we get 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Moving on to step 13:
158 goes into 780 4 times with a remainder of 148.
The next digit of our result is 4. 
Result so far: 117830.57594
The remainder is 148 after subtracting 632 from 780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

Let's proceed to step 14:
158 can be fit into 1480 9 times, resulting in a remainder of 58.
The next digit of our result is 9. 
Result so far: 117830.575949
The remainder is 58 after subtracting 1422 from 1480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Advancing to step 15:
When dividing 580 by 158, we get 3 with a remainder of 106.
Put 3 as the next digit of the answer. 
Result so far: 117830.5759493
Subtracting 474 from 580 leaves us with 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Step 16:
If we divide 1060 by 158, we get 6 and a remainder of 112.
Use 6 as the next digit of our solution. 
Result so far: 117830.57594936
If we take 948 away from 1060, we end up with 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

The final outcome is 117830.57594936, with a leftover of 1.12e-07.
