We're dividing 70494678 by 155 
The aim is to understand the frequency of 155 in 70494678.

Advancing to step 1:
If we divide 7 by 155, we get 0 and a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Append the next digit (0) from the dividend to 7 and continue with: 70 / 155

Moving on to step 2:
155 can be fit into 70 0 times, resulting in a remainder of 70.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 70, we get 70.
Fetch the next digit (4) from the dividend, attach it to 70 and continue: 704 / 155

Moving on to step 3:
If we divide 704 by 155, we get 4 and a remainder of 84.
Put 4 as the next digit of the answer. 
Result so far: 4.0
If we subtract 620 from 704, we get 84.
Fetch the next digit (9) from the dividend, attach it to 84 and continue: 849 / 155

On to step 4:
If we divide 849 by 155, we get 5 and a remainder of 74.
Use 5 as the next digit of our solution. 
Result so far: 45.0
Deduct 775 from 849 and we're left with 74.
Include the next digit (4) from the dividend after 74, then repeat: 744 / 155

Step 5:
155 can be fit into 744 4 times, resulting in a remainder of 124.
Record the quotient 4 as the next digit in the result. 
Result so far: 454.0
Subtracting 620 from 744 leaves us with 124.
Append the next digit (6) from the dividend to 124 and continue with: 1246 / 155

Advancing to step 6:
155 can be fit into 1246 8 times, resulting in a remainder of 6.
Write down 8 as next digit of the result. 
Result so far: 4548.0
Subtracting 1240 from 1246 leaves us with 6.
Bring next digit (7) of the dividend behind the 6 and repeat the process: 67 / 155

Moving on to step 7:
The number 155 fits into 67 0 times, leaving a remainder of 67.
Use 0 as the next digit of our solution. 
Result so far: 45480.0
Subtracting 0 from 67 leaves us with 67.
Grab the next digit (8) from the dividend, add it to 67, then carry on: 678 / 155

Going ahead to step 8:
678 divided by 155 is 4 with a remainder of 58.
Record the quotient 4 as the next digit in the result. 
Result so far: 454804.0
If we subtract 620 from 678, we get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Moving on to step 9:
155 can be fit into 580 3 times, resulting in a remainder of 115.
Put 3 as the next digit of the answer. 
Result so far: 454804.3
Subtracting 465 from 580 leaves us 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.

Going ahead to step 10:
If we divide 1150 by 155, we get 7 and a remainder of 65.
The number 7 becomes the next digit in our result. 
Result so far: 454804.37
If we take 1085 away from 1150, we end up with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Advancing to step 11:
The number 155 fits into 650 4 times, leaving a remainder of 30.
Record the quotient 4 as the next digit in the result. 
Result so far: 454804.374
Subtracting 620 from 650 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 12:
155 can be fit into 300 1 times, resulting in a remainder of 145.
The number 1 becomes the next digit in our result. 
Result so far: 454804.3741
The remainder is 145 after subtracting 155 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

Step 13:
The number 155 fits into 1450 9 times, leaving a remainder of 55.
Record the quotient 9 as the next digit in the result. 
Result so far: 454804.37419
Deduct 1395 from 1450 and we're left with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Step 14:
If we divide 550 by 155, we get 3 and a remainder of 85.
Put 3 as the next digit of the answer. 
Result so far: 454804.374193
The remainder is 85 after subtracting 465 from 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Moving on to step 15:
155 goes into 850 5 times with a remainder of 75.
Use 5 as the next digit of our solution. 
Result so far: 454804.3741935
The remainder is 75 after subtracting 775 from 850.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Step 16:
155 goes into 750 4 times with a remainder of 130.
Write down 4 as next digit of the result. 
Result so far: 454804.37419354
If we take 620 away from 750, we end up with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Our division results in 454804.37419354 with a remaining 1.3e-07.
