We divide 72485968 by 355
The aim is to understand the frequency of 355 in 72485968.

Step 1:
7 divided by 355 is 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Take the next digit (2) from the dividend and append it to 7, then repeat: 72 / 355

Advancing to step 2:
If we divide 72 by 355, we get 0 and a remainder of 72.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 72, we end up with 72.
Grab the next digit (4) from the dividend, add it to 72, then carry on: 724 / 355

Moving on to step 3:
The number 355 fits into 724 2 times, leaving a remainder of 14.
Use 2 as the next digit of our solution. 
Result so far: 2.0
The remainder is 14 after subtracting 710 from 724.
Take the next digit (8) from the dividend and append it to 14, then repeat: 148 / 355

Step 4:
355 can be fit into 148 0 times, resulting in a remainder of 148.
Write down 0 as next digit of the result. 
Result so far: 20.0
Deduct 0 from 148 and we're left with 148.
Bring next digit (5) of the dividend behind the 148 and repeat the process: 1485 / 355

Let's proceed to step 5:
1485 divided by 355 is 4 with a remainder of 65.
Put 4 as the next digit of the answer. 
Result so far: 204.0
If we subtract 1420 from 1485, we get 65.
Append the next digit (9) from the dividend to 65 and continue with: 659 / 355

Advancing to step 6:
The number 355 fits into 659 1 times, leaving a remainder of 304.
Write down 1 as next digit of the result. 
Result so far: 2041.0
Subtract 355 from 659 to get 304.
Include the next digit (6) from the dividend after 304, then repeat: 3046 / 355

Going ahead to step 7:
355 goes into 3046 8 times with a remainder of 206.
The next digit of our result is 8. 
Result so far: 20418.0
If we take 2840 away from 3046, we end up with 206.
Append the next digit (8) from the dividend to 206 and continue with: 2068 / 355

Advancing to step 8:
2068 divided by 355 is 5 with a remainder of 293.
Record the quotient 5 as the next digit in the result. 
Result so far: 204185.0
Subtract 1775 from 2068 to get 293.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2930, and continue the process.

Going ahead to step 9:
When dividing 2930 by 355, we get 8 with a remainder of 90.
The number 8 becomes the next digit in our result. 
Result so far: 204185.8
Subtracting 2840 from 2930 leaves us with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Moving on to step 10:
If we divide 900 by 355, we get 2 and a remainder of 190.
The next digit of our result is 2. 
Result so far: 204185.82
If we subtract 710 from 900, we get 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

On to step 11:
355 can be fit into 1900 5 times, resulting in a remainder of 125.
Use 5 as the next digit of our solution. 
Result so far: 204185.825
Deduct 1775 from 1900 and we're left with 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

On to step 12:
When dividing 1250 by 355, we get 3 with a remainder of 185.
The next digit of our result is 3. 
Result so far: 204185.8253
Subtracting 1065 from 1250 leaves us with 185.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

Step 13:
When dividing 1850 by 355, we get 5 with a remainder of 75.
Record the quotient 5 as the next digit in the result. 
Result so far: 204185.82535
Subtract 1775 from 1850 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.

Advancing to step 14:
If we divide 750 by 355, we get 2 and a remainder of 40.
Record the quotient 2 as the next digit in the result. 
Result so far: 204185.825352
Subtracting 710 from 750 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 15:
355 can be fit into 400 1 times, resulting in a remainder of 45.
The next digit of our result is 1. 
Result so far: 204185.8253521
Deduct 355 from 400 and we're left 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.

Let's proceed to step 16:
If we divide 450 by 355, we get 1 and a remainder of 95.
The next digit of our result is 1. 
Result so far: 204185.82535211
Deduct 355 from 450 and we're left 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.

The final outcome is 204185.82535211, with a leftover of 9.5e-08.
