We divide 28686593 by 155
The aim is to understand the frequency of 155 in 28686593.

Moving on to step 1:
The number 155 fits into 2 0 times, leaving a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Append the next digit (8) from the dividend to 2 and continue with: 28 / 155

Step 2:
When dividing 28 by 155, we get 0 with a remainder of 28.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 28 leaves us with 28.
Include the next digit (6) from the dividend after 28, then repeat: 286 / 155

Let's proceed to step 3:
155 goes into 286 1 times with a remainder of 131.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 155 from 286 leaves us with 131.
Grab the next digit (8) from the dividend, add it to 131, then carry on: 1318 / 155

Step 4:
155 goes into 1318 8 times with a remainder of 78.
Put 8 as the next digit of the answer. 
Result so far: 18.0
If we subtract 1240 from 1318, we get 78.
Bring next digit (6) of the dividend behind the 78 and repeat the process: 786 / 155

Let's proceed to step 5:
When dividing 786 by 155, we get 5 with a remainder of 11.
The next digit of our result is 5. 
Result so far: 185.0
If we take 775 away from 786, we end up with 11.
Grab the next digit (5) from the dividend, add it to 11, then carry on: 115 / 155

On to step 6:
155 goes into 115 0 times with a remainder of 115.
Use 0 as the next digit of our solution. 
Result so far: 1850.0
The remainder is 115 after subtracting 0 from 115.
Take the next digit (9) from the dividend and append it to 115, then repeat: 1159 / 155

On to step 7:
155 goes into 1159 7 times with a remainder of 74.
Put 7 as the next digit of the answer. 
Result so far: 18507.0
If we take 1085 away from 1159, we end up with 74.
Fetch the next digit (3) from the dividend, attach it to 74 and continue: 743 / 155

Advancing to step 8:
The number 155 fits into 743 4 times, leaving a remainder of 123.
The next digit of our result is 4. 
Result so far: 185074.0
Subtracting 620 from 743 leaves us with 123.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1230, and continue the process.

Advancing to step 9:
When dividing 1230 by 155, we get 7 with a remainder of 145.
The number 7 becomes the next digit in our result. 
Result so far: 185074.7
If we subtract 1085 from 1230, 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.

Advancing to step 10:
If we divide 1450 by 155, we get 9 and a remainder of 55.
The number 9 becomes the next digit in our result. 
Result so far: 185074.79
If we take 1395 away from 1450, we end up 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.

On to step 11:
The number 155 fits into 550 3 times, leaving a remainder of 85.
Use 3 as the next digit of our solution. 
Result so far: 185074.793
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.

Advancing to step 12:
When dividing 850 by 155, we get 5 with a remainder of 75.
The next digit of our result is 5. 
Result so far: 185074.7935
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 13:
155 can be fit into 750 4 times, resulting in a remainder of 130.
Record the quotient 4 as the next digit in the result. 
Result so far: 185074.79354
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.

Advancing to step 14:
155 can be fit into 1300 8 times, resulting in a remainder of 60.
Put 8 as the next digit of the answer. 
Result so far: 185074.793548
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.

Moving on to step 15:
When dividing 600 by 155, we get 3 with a remainder of 135.
Record the quotient 3 as the next digit in the result. 
Result so far: 185074.7935483
If we subtract 465 from 600, we get 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

Step 16:
155 can be fit into 1350 8 times, resulting in a remainder of 110.
Use 8 as the next digit of our solution. 
Result so far: 185074.79354838
If we take 1240 away from 1350, we end up with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

The quotient of the division is 185074.79354838, and the remainder is 1.1e-07.
