45216586 divided by 155 
The aim is to understand the frequency of 155 in 45216586.

Advancing to step 1:
If we divide 4 by 155, we get 0 and a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Include the next digit (5) from the dividend after 4, then repeat: 45 / 155

Going ahead to step 2:
45 divided by 155 is 0 with a remainder of 45.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 45 after subtracting 0 from 45.
Append the next digit (2) from the dividend to 45 and continue with: 452 / 155

Moving on to step 3:
452 divided by 155 is 2 with a remainder of 142.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtract 310 from 452 to get 142.
Take the next digit (1) from the dividend and append it to 142, then repeat: 1421 / 155

Moving on to step 4:
1421 divided by 155 is 9 with a remainder of 26.
The number 9 becomes the next digit in our result. 
Result so far: 29.0
If we subtract 1395 from 1421, we get 26.
Grab the next digit (6) from the dividend, add it to 26, then carry on: 266 / 155

On to step 5:
When dividing 266 by 155, we get 1 with a remainder of 111.
Put 1 as the next digit of the answer. 
Result so far: 291.0
Subtracting 155 from 266 leaves us with 111.
Take the next digit (5) from the dividend and append it to 111, then repeat: 1115 / 155

On to step 6:
155 goes into 1115 7 times with a remainder of 30.
The next digit of our result is 7. 
Result so far: 2917.0
If we subtract 1085 from 1115, we get 30.
Take the next digit (8) from the dividend and append it to 30, then repeat: 308 / 155

Step 7:
The number 155 fits into 308 1 times, leaving a remainder of 153.
Write down 1 as next digit of the result. 
Result so far: 29171.0
Subtracting 155 from 308 leaves us with 153.
Grab the next digit (6) from the dividend, add it to 153, then carry on: 1536 / 155

Advancing to step 8:
The number 155 fits into 1536 9 times, leaving a remainder of 141.
The number 9 becomes the next digit in our result. 
Result so far: 291719.0
If we subtract 1395 from 1536, we get 141.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1410, and continue the process.

Going ahead to step 9:
If we divide 1410 by 155, we get 9 and a remainder of 15.
Write down 9 as next digit of the result. 
Result so far: 291719.9
Subtracting 1395 from 1410 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.

Step 10:
If we divide 150 by 155, we get 0 and a remainder of 150.
Put 0 as the next digit of the answer. 
Result so far: 291719.9
The remainder is 150 after subtracting 0 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Step 11:
155 goes into 1500 9 times with a remainder of 105.
The number 9 becomes the next digit in our result. 
Result so far: 291719.909
Deduct 1395 from 1500 and we're left with 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

Let's proceed to step 12:
The number 155 fits into 1050 6 times, leaving a remainder of 120.
Write down 6 as next digit of the result. 
Result so far: 291719.9096
Deduct 930 from 1050 and we're left 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.

Advancing to step 13:
155 goes into 1200 7 times with a remainder of 115.
Put 7 as the next digit of the answer. 
Result so far: 291719.90967
Subtract 1085 from 1200 to get 115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

Advancing to step 14:
155 goes into 1150 7 times with a remainder of 65.
Write down 7 as next digit of the result. 
Result so far: 291719.909677
The remainder is 65 after subtracting 1085 from 1150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

The final result is 291719.909677 with a remainder of 6.5e-06.
