18259812 ÷ 155 
We want to figure out the number of times 18259812 can be divided by 155.

Going ahead to step 1:
When dividing 1 by 155, we get 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Take the next digit (8) from the dividend and append it to 1, then repeat: 18 / 155

On to step 2:
When dividing 18 by 155, we get 0 with a remainder of 18.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 18 leaves us with 18.
Append the next digit (2) from the dividend to 18 and continue with: 182 / 155

Going ahead to step 3:
The number 155 fits into 182 1 times, leaving a remainder of 27.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 155 from 182 leaves us with 27.
Grab the next digit (5) from the dividend, add it to 27, then carry on: 275 / 155

Advancing to step 4:
275 divided by 155 is 1 with a remainder of 120.
Put 1 as the next digit of the answer. 
Result so far: 11.0
Subtract 155 from 275 to get 120.
Append the next digit (9) from the dividend to 120 and continue with: 1209 / 155

Going ahead to step 5:
If we divide 1209 by 155, we get 7 and a remainder of 124.
Use 7 as the next digit of our solution. 
Result so far: 117.0
If we subtract 1085 from 1209, we get 124.
Include the next digit (8) from the dividend after 124, then repeat: 1248 / 155

Step 6:
155 goes into 1248 8 times with a remainder of 8.
Write down 8 as next digit of the result. 
Result so far: 1178.0
Deduct 1240 from 1248 and we're left with 8.
Fetch the next digit (1) from the dividend, attach it to 8 and continue: 81 / 155

Let's proceed to step 7:
155 can be fit into 81 0 times, resulting in a remainder of 81.
Use 0 as the next digit of our solution. 
Result so far: 11780.0
Subtracting 0 from 81 leaves us with 81.
Append the next digit (2) from the dividend to 81 and continue with: 812 / 155

Moving on to step 8:
155 goes into 812 5 times with a remainder of 37.
Use 5 as the next digit of our solution. 
Result so far: 117805.0
The remainder is 37 after subtracting 775 from 812.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Let's proceed to step 9:
The number 155 fits into 370 2 times, leaving a remainder of 60.
The next digit of our result is 2. 
Result so far: 117805.2
Subtracting 310 from 370 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 10:
155 can be fit into 600 3 times, resulting in a remainder of 135.
Record the quotient 3 as the next digit in the result. 
Result so far: 117805.23
Subtract 465 from 600 to get 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

Let's proceed to step 11:
When dividing 1350 by 155, we get 8 with a remainder of 110.
Use 8 as the next digit of our solution. 
Result so far: 117805.238
Deduct 1240 from 1350 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.

Step 12:
155 can be fit into 1100 7 times, resulting in a remainder of 15.
Use 7 as the next digit of our solution. 
Result so far: 117805.2387
Subtracting 1085 from 1100 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 13:
When dividing 150 by 155, we get 0 with a remainder of 150.
The number 0 becomes the next digit in our result. 
Result so far: 117805.2387
Subtracting 0 from 150 leaves us 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.

Going ahead to step 14:
155 can be fit into 1500 9 times, resulting in a remainder of 105.
Put 9 as the next digit of the answer. 
Result so far: 117805.238709
The remainder is 105 after subtracting 1395 from 1500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

Step 15:
1050 divided by 155 is 6 with a remainder of 120.
Put 6 as the next digit of the answer. 
Result so far: 117805.2387096
The remainder is 120 after subtracting 930 from 1050.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Advancing to step 16:
155 can be fit into 1200 7 times, resulting in a remainder of 115.
The number 7 becomes the next digit in our result. 
Result so far: 117805.23870967
Deduct 1085 from 1200 and we're left with 115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

The final outcome is 117805.23870967, with a leftover of 1.15e-07.
