91225159 ÷ 155 
We're looking to find how many times 155 goes into 91225159.

Step 1:
If we divide 9 by 155, we get 0 and a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Include the next digit (1) from the dividend after 9, then repeat: 91 / 155

Moving on to step 2:
If we divide 91 by 155, we get 0 and a remainder of 91.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 91, we end up with 91.
Fetch the next digit (2) from the dividend, attach it to 91 and continue: 912 / 155

Moving on to step 3:
155 goes into 912 5 times with a remainder of 137.
The next digit of our result is 5. 
Result so far: 5.0
Subtracting 775 from 912 leaves us with 137.
Bring next digit (2) of the dividend behind the 137 and repeat the process: 1372 / 155

On to step 4:
155 goes into 1372 8 times with a remainder of 132.
Record the quotient 8 as the next digit in the result. 
Result so far: 58.0
Subtracting 1240 from 1372 leaves us with 132.
Append the next digit (5) from the dividend to 132 and continue with: 1325 / 155

Advancing to step 5:
155 goes into 1325 8 times with a remainder of 85.
The next digit of our result is 8. 
Result so far: 588.0
Subtracting 1240 from 1325 leaves us with 85.
Fetch the next digit (1) from the dividend, attach it to 85 and continue: 851 / 155

On to step 6:
When dividing 851 by 155, we get 5 with a remainder of 76.
Record the quotient 5 as the next digit in the result. 
Result so far: 5885.0
Subtracting 775 from 851 leaves us with 76.
Grab the next digit (5) from the dividend, add it to 76, then carry on: 765 / 155

Let's proceed to step 7:
155 goes into 765 4 times with a remainder of 145.
The next digit of our result is 4. 
Result so far: 58854.0
The remainder is 145 after subtracting 620 from 765.
Fetch the next digit (9) from the dividend, attach it to 145 and continue: 1459 / 155

Let's proceed to step 8:
155 goes into 1459 9 times with a remainder of 64.
Put 9 as the next digit of the answer. 
Result so far: 588549.0
Subtracting 1395 from 1459 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 9:
When dividing 640 by 155, we get 4 with a remainder of 20.
The next digit of our result is 4. 
Result so far: 588549.4
The remainder is 20 after subtracting 620 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 10:
155 can be fit into 200 1 times, resulting in a remainder of 45.
The next digit of our result is 1. 
Result so far: 588549.41
The remainder is 45 after subtracting 155 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Moving on to step 11:
If we divide 450 by 155, we get 2 and a remainder of 140.
The next digit of our result is 2. 
Result so far: 588549.412
Subtracting 310 from 450 leaves us with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

On to step 12:
155 goes into 1400 9 times with a remainder of 5.
Record the quotient 9 as the next digit in the result. 
Result so far: 588549.4129
Subtract 1395 from 1400 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 13:
50 divided by 155 is 0 with a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 588549.4129
The remainder is 50 after subtracting 0 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 14:
155 can be fit into 500 3 times, resulting in a remainder of 35.
The number 3 becomes the next digit in our result. 
Result so far: 588549.412903
If we take 465 away from 500, we end up with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Let's proceed to step 15:
The number 155 fits into 350 2 times, leaving a remainder of 40.
Record the quotient 2 as the next digit in the result. 
Result so far: 588549.4129032
Subtracting 310 from 350 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 16:
155 goes into 400 2 times with a remainder of 90.
The next digit of our result is 2. 
Result so far: 588549.41290322
If we take 310 away from 400, we end up with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

In conclusion, the division gives 588549.41290322 with a balance of 9e-08.
