We look at the division of 1671764 by 155 
The aim is to understand the frequency of 155 in 1671764.

Step 1:
155 can be fit into 1 0 times, resulting in a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Append the next digit (6) from the dividend to 1 and continue with: 16 / 155

On to step 2:
16 divided by 155 is 0 with a remainder of 16.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 16 and we're left with 16.
Take the next digit (7) from the dividend and append it to 16, then repeat: 167 / 155

Advancing to step 3:
When dividing 167 by 155, we get 1 with a remainder of 12.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 12 after subtracting 155 from 167.
Fetch the next digit (1) from the dividend, attach it to 12 and continue: 121 / 155

Let's proceed to step 4:
155 goes into 121 0 times with a remainder of 121.
The next digit of our result is 0. 
Result so far: 10.0
Subtract 0 from 121 to get 121.
Grab the next digit (7) from the dividend, add it to 121, then carry on: 1217 / 155

Let's proceed to step 5:
When dividing 1217 by 155, we get 7 with a remainder of 132.
Use 7 as the next digit of our solution. 
Result so far: 107.0
If we take 1085 away from 1217, we end up with 132.
Bring next digit (6) of the dividend behind the 132 and repeat the process: 1326 / 155

Going ahead to step 6:
The number 155 fits into 1326 8 times, leaving a remainder of 86.
Use 8 as the next digit of our solution. 
Result so far: 1078.0
Subtract 1240 from 1326 to get 86.
Take the next digit (4) from the dividend and append it to 86, then repeat: 864 / 155

Advancing to step 7:
If we divide 864 by 155, we get 5 and a remainder of 89.
Write down 5 as next digit of the result. 
Result so far: 10785.0
Deduct 775 from 864 and we're left with 89.
Since there are no more digits in the dividend, we add a zero to the remainder making it 890, and continue the process.

On to step 8:
890 divided by 155 is 5 with a remainder of 115.
The next digit of our result is 5. 
Result so far: 10785.5
Subtract 775 from 890 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.

Going ahead to step 9:
155 goes into 1150 7 times with a remainder of 65.
Record the quotient 7 as the next digit in the result. 
Result so far: 10785.57
Deduct 1085 from 1150 and we're left 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.

On to step 10:
650 divided by 155 is 4 with a remainder of 30.
Use 4 as the next digit of our solution. 
Result so far: 10785.574
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.

Let's proceed to step 11:
The number 155 fits into 300 1 times, leaving a remainder of 145.
Write down 1 as next digit of the result. 
Result so far: 10785.5741
If we subtract 155 from 300, we get 145.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

Let's proceed to step 12:
1450 divided by 155 is 9 with a remainder of 55.
Record the quotient 9 as the next digit in the result. 
Result so far: 10785.57419
The remainder is 55 after subtracting 1395 from 1450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Advancing to step 13:
The number 155 fits into 550 3 times, leaving a remainder of 85.
The next digit of our result is 3. 
Result so far: 10785.574193
Deduct 465 from 550 and we're left 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.

Let's proceed to step 14:
When dividing 850 by 155, we get 5 with a remainder of 75.
Record the quotient 5 as the next digit in the result. 
Result so far: 10785.5741935
Subtract 775 from 850 to get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Let's proceed to step 15:
When dividing 750 by 155, we get 4 with a remainder of 130.
Put 4 as the next digit of the answer. 
Result so far: 10785.57419354
The remainder is 130 after subtracting 620 from 750.
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 10785.57419354 with a remaining 1.3e-07.
