We look at the division of 80815566 by 154 
We're looking to find how many times 154 goes into 80815566.

On to step 1:
154 can be fit into 8 0 times, resulting in a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Take the next digit (0) from the dividend and append it to 8, then repeat: 80 / 154

Moving on to step 2:
When dividing 80 by 154, we get 0 with a remainder of 80.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 80 leaves us with 80.
Fetch the next digit (8) from the dividend, attach it to 80 and continue: 808 / 154

On to step 3:
154 can be fit into 808 5 times, resulting in a remainder of 38.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
If we take 770 away from 808, we end up with 38.
Fetch the next digit (1) from the dividend, attach it to 38 and continue: 381 / 154

Moving on to step 4:
If we divide 381 by 154, we get 2 and a remainder of 73.
The next digit of our result is 2. 
Result so far: 52.0
If we take 308 away from 381, we end up with 73.
Take the next digit (5) from the dividend and append it to 73, then repeat: 735 / 154

Let's proceed to step 5:
154 can be fit into 735 4 times, resulting in a remainder of 119.
Write down 4 as next digit of the result. 
Result so far: 524.0
Deduct 616 from 735 and we're left with 119.
Fetch the next digit (5) from the dividend, attach it to 119 and continue: 1195 / 154

Moving on to step 6:
The number 154 fits into 1195 7 times, leaving a remainder of 117.
Put 7 as the next digit of the answer. 
Result so far: 5247.0
Subtract 1078 from 1195 to get 117.
Fetch the next digit (6) from the dividend, attach it to 117 and continue: 1176 / 154

On to step 7:
154 can be fit into 1176 7 times, resulting in a remainder of 98.
The number 7 becomes the next digit in our result. 
Result so far: 52477.0
Subtract 1078 from 1176 to get 98.
Append the next digit (6) from the dividend to 98 and continue with: 986 / 154

Moving on to step 8:
154 can be fit into 986 6 times, resulting in a remainder of 62.
Use 6 as the next digit of our solution. 
Result so far: 524776.0
Deduct 924 from 986 and we're left with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Step 9:
The number 154 fits into 620 4 times, leaving a remainder of 4.
The next digit of our result is 4. 
Result so far: 524776.4
The remainder is 4 after subtracting 616 from 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 10:
154 can be fit into 40 0 times, resulting in a remainder of 40.
The next digit of our result is 0. 
Result so far: 524776.4
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 11:
400 divided by 154 is 2 with a remainder of 92.
Record the quotient 2 as the next digit in the result. 
Result so far: 524776.402
Deduct 308 from 400 and we're left with 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Moving on to step 12:
920 divided by 154 is 5 with a remainder of 150.
Put 5 as the next digit of the answer. 
Result so far: 524776.4025
The remainder is 150 after subtracting 770 from 920.
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 13:
The number 154 fits into 1500 9 times, leaving a remainder of 114.
The next digit of our result is 9. 
Result so far: 524776.40259
The remainder is 114 after subtracting 1386 from 1500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

Advancing to step 14:
If we divide 1140 by 154, we get 7 and a remainder of 62.
Put 7 as the next digit of the answer. 
Result so far: 524776.402597
The remainder is 62 after subtracting 1078 from 1140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Let's proceed to step 15:
When dividing 620 by 154, we get 4 with a remainder of 4.
Use 4 as the next digit of our solution. 
Result so far: 524776.4025974
The remainder is 4 after subtracting 616 from 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 16:
When dividing 40 by 154, we get 0 with a remainder of 40.
The next digit of our result is 0. 
Result so far: 524776.4025974
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

After the division, we end up with 524776.4025974 and a remainder of 4e-08.
