70744194 ÷ 155 
The aim is to understand the frequency of 155 in 70744194.

On to step 1:
If we divide 7 by 155, we get 0 and a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Fetch the next digit (0) from the dividend, attach it to 7 and continue: 70 / 155

On to step 2:
70 divided by 155 is 0 with a remainder of 70.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 70 and we're left with 70.
Fetch the next digit (7) from the dividend, attach it to 70 and continue: 707 / 155

On to step 3:
707 divided by 155 is 4 with a remainder of 87.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Deduct 620 from 707 and we're left with 87.
Take the next digit (4) from the dividend and append it to 87, then repeat: 874 / 155

Moving on to step 4:
155 can be fit into 874 5 times, resulting in a remainder of 99.
The number 5 becomes the next digit in our result. 
Result so far: 45.0
The remainder is 99 after subtracting 775 from 874.
Fetch the next digit (4) from the dividend, attach it to 99 and continue: 994 / 155

Moving on to step 5:
994 divided by 155 is 6 with a remainder of 64.
The number 6 becomes the next digit in our result. 
Result so far: 456.0
Deduct 930 from 994 and we're left with 64.
Fetch the next digit (1) from the dividend, attach it to 64 and continue: 641 / 155

Advancing to step 6:
155 can be fit into 641 4 times, resulting in a remainder of 21.
The number 4 becomes the next digit in our result. 
Result so far: 4564.0
Subtracting 620 from 641 leaves us with 21.
Include the next digit (9) from the dividend after 21, then repeat: 219 / 155

Step 7:
The number 155 fits into 219 1 times, leaving a remainder of 64.
Put 1 as the next digit of the answer. 
Result so far: 45641.0
If we take 155 away from 219, we end up with 64.
Grab the next digit (4) from the dividend, add it to 64, then carry on: 644 / 155

Moving on to step 8:
If we divide 644 by 155, we get 4 and a remainder of 24.
The number 4 becomes the next digit in our result. 
Result so far: 456414.0
If we take 620 away from 644, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 9:
When dividing 240 by 155, we get 1 with a remainder of 85.
The next digit of our result is 1. 
Result so far: 456414.1
If we take 155 away from 240, we end up with 85.
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 10:
155 can be fit into 850 5 times, resulting in a remainder of 75.
The number 5 becomes the next digit in our result. 
Result so far: 456414.15
Subtracting 775 from 850 leaves us with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Moving on to step 11:
155 goes into 750 4 times with a remainder of 130.
Record the quotient 4 as the next digit in the result. 
Result so far: 456414.154
If we subtract 620 from 750, we get 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Let's proceed to step 12:
155 goes into 1300 8 times with a remainder of 60.
The number 8 becomes the next digit in our result. 
Result so far: 456414.1548
Subtracting 1240 from 1300 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.

Step 13:
If we divide 600 by 155, we get 3 and a remainder of 135.
The number 3 becomes the next digit in our result. 
Result so far: 456414.15483
If we take 465 away from 600, we end up with 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

Moving on to step 14:
1350 divided by 155 is 8 with a remainder of 110.
The number 8 becomes the next digit in our result. 
Result so far: 456414.154838
Subtract 1240 from 1350 to get 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Let's proceed to step 15:
If we divide 1100 by 155, we get 7 and a remainder of 15.
The next digit of our result is 7. 
Result so far: 456414.1548387
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 16:
155 can be fit into 150 0 times, resulting in a remainder of 150.
The number 0 becomes the next digit in our result. 
Result so far: 456414.1548387
Deduct 0 from 150 and we're left 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.

The final result is 456414.1548387 with a remainder of 1.5e-07.
