We're dividing 89469887 by 355 
The aim is to understand the frequency of 355 in 89469887.

On to step 1:
355 can be fit into 8 0 times, resulting in a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Take the next digit (9) from the dividend and append it to 8, then repeat: 89 / 355

On to step 2:
355 goes into 89 0 times with a remainder of 89.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 89 to get 89.
Append the next digit (4) from the dividend to 89 and continue with: 894 / 355

Moving on to step 3:
The number 355 fits into 894 2 times, leaving a remainder of 184.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtract 710 from 894 to get 184.
Append the next digit (6) from the dividend to 184 and continue with: 1846 / 355

Advancing to step 4:
If we divide 1846 by 355, we get 5 and a remainder of 71.
The number 5 becomes the next digit in our result. 
Result so far: 25.0
Subtract 1775 from 1846 to get 71.
Bring next digit (9) of the dividend behind the 71 and repeat the process: 719 / 355

Moving on to step 5:
355 can be fit into 719 2 times, resulting in a remainder of 9.
Write down 2 as next digit of the result. 
Result so far: 252.0
Subtracting 710 from 719 leaves us with 9.
Fetch the next digit (8) from the dividend, attach it to 9 and continue: 98 / 355

Moving on to step 6:
355 can be fit into 98 0 times, resulting in a remainder of 98.
Put 0 as the next digit of the answer. 
Result so far: 2520.0
Subtract 0 from 98 to get 98.
Include the next digit (8) from the dividend after 98, then repeat: 988 / 355

On to step 7:
355 can be fit into 988 2 times, resulting in a remainder of 278.
Write down 2 as next digit of the result. 
Result so far: 25202.0
If we take 710 away from 988, we end up with 278.
Append the next digit (7) from the dividend to 278 and continue with: 2787 / 355

Let's proceed to step 8:
If we divide 2787 by 355, we get 7 and a remainder of 302.
Put 7 as the next digit of the answer. 
Result so far: 252027.0
Subtracting 2485 from 2787 leaves us with 302.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3020, and continue the process.

Going ahead to step 9:
When dividing 3020 by 355, we get 8 with a remainder of 180.
The number 8 becomes the next digit in our result. 
Result so far: 252027.8
If we subtract 2840 from 3020, we get 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

On to step 10:
355 goes into 1800 5 times with a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 252027.85
Subtracting 1775 from 1800 leaves us 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 11:
When dividing 250 by 355, we get 0 with a remainder of 250.
The next digit of our result is 0. 
Result so far: 252027.85
The remainder is 250 after subtracting 0 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

On to step 12:
The number 355 fits into 2500 7 times, leaving a remainder of 15.
Use 7 as the next digit of our solution. 
Result so far: 252027.8507
The remainder is 15 after subtracting 2485 from 2500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 13:
The number 355 fits into 150 0 times, leaving a remainder of 150.
Put 0 as the next digit of the answer. 
Result so far: 252027.8507
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.

On to step 14:
1500 divided by 355 is 4 with a remainder of 80.
Write down 4 as next digit of the result. 
Result so far: 252027.850704
If we take 1420 away from 1500, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Advancing to step 15:
355 goes into 800 2 times with a remainder of 90.
The number 2 becomes the next digit in our result. 
Result so far: 252027.8507042
The remainder is 90 after subtracting 710 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Advancing to step 16:
355 goes into 900 2 times with a remainder of 190.
Put 2 as the next digit of the answer. 
Result so far: 252027.85070422
The remainder is 190 after subtracting 710 from 900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Our division results in 252027.85070422 with a remaining 1.9e-07.
