We're dividing 97590149 by 155 
The aim is to understand the frequency of 155 in 97590149.

Step 1:
When dividing 9 by 155, we get 0 with 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.
Grab the next digit (7) from the dividend, add it to 9, then carry on: 97 / 155

On to step 2:
If we divide 97 by 155, we get 0 and a remainder of 97.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 97, we get 97.
Fetch the next digit (5) from the dividend, attach it to 97 and continue: 975 / 155

Advancing to step 3:
975 divided by 155 is 6 with a remainder of 45.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
Subtract 930 from 975 to get 45.
Append the next digit (9) from the dividend to 45 and continue with: 459 / 155

Let's proceed to step 4:
459 divided by 155 is 2 with a remainder of 149.
The next digit of our result is 2. 
Result so far: 62.0
If we take 310 away from 459, we end up with 149.
Grab the next digit (0) from the dividend, add it to 149, then carry on: 1490 / 155

On to step 5:
If we divide 1490 by 155, we get 9 and a remainder of 95.
Put 9 as the next digit of the answer. 
Result so far: 629.0
Subtract 1395 from 1490 to get 95.
Bring next digit (1) of the dividend behind the 95 and repeat the process: 951 / 155

Advancing to step 6:
When dividing 951 by 155, we get 6 with a remainder of 21.
Use 6 as the next digit of our solution. 
Result so far: 6296.0
The remainder is 21 after subtracting 930 from 951.
Grab the next digit (4) from the dividend, add it to 21, then carry on: 214 / 155

Going ahead to step 7:
When dividing 214 by 155, we get 1 with a remainder of 59.
Put 1 as the next digit of the answer. 
Result so far: 62961.0
If we subtract 155 from 214, we get 59.
Bring next digit (9) of the dividend behind the 59 and repeat the process: 599 / 155

Step 8:
If we divide 599 by 155, we get 3 and a remainder of 134.
The next digit of our result is 3. 
Result so far: 629613.0
Subtract 465 from 599 to get 134.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

On to step 9:
155 can be fit into 1340 8 times, resulting in a remainder of 100.
Put 8 as the next digit of the answer. 
Result so far: 629613.8
Deduct 1240 from 1340 and we're left with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

On to step 10:
When dividing 1000 by 155, we get 6 with a remainder of 70.
The number 6 becomes the next digit in our result. 
Result so far: 629613.86
Subtracting 930 from 1000 leaves us with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Step 11:
155 goes into 700 4 times with a remainder of 80.
Write down 4 as next digit of the result. 
Result so far: 629613.864
The remainder is 80 after subtracting 620 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 12:
155 goes into 800 5 times with a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 629613.8645
If we take 775 away from 800, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 13:
155 goes into 250 1 times with a remainder of 95.
Record the quotient 1 as the next digit in the result. 
Result so far: 629613.86451
Subtracting 155 from 250 leaves us with 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

Going ahead to step 14:
When dividing 950 by 155, we get 6 with a remainder of 20.
Use 6 as the next digit of our solution. 
Result so far: 629613.864516
Subtract 930 from 950 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 15:
If we divide 200 by 155, we get 1 and a remainder of 45.
Record the quotient 1 as the next digit in the result. 
Result so far: 629613.8645161
Subtracting 155 from 200 leaves us with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

On to step 16:
155 can be fit into 450 2 times, resulting in a remainder of 140.
Record the quotient 2 as the next digit in the result. 
Result so far: 629613.86451612
If we subtract 310 from 450, we get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

The final result is 629613.86451612 with a remainder of 1.4e-07.
