86539715 ÷ 355 
The aim is to understand the frequency of 355 in 86539715.

Going ahead to step 1:
The number 355 fits into 8 0 times, leaving a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Bring next digit (6) of the dividend behind the 8 and repeat the process: 86 / 355

Advancing to step 2:
The number 355 fits into 86 0 times, leaving a remainder of 86.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 86 to get 86.
Append the next digit (5) from the dividend to 86 and continue with: 865 / 355

Let's proceed to step 3:
When dividing 865 by 355, we get 2 with a remainder of 155.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
The remainder is 155 after subtracting 710 from 865.
Append the next digit (3) from the dividend to 155 and continue with: 1553 / 355

Let's proceed to step 4:
If we divide 1553 by 355, we get 4 and a remainder of 133.
Write down 4 as next digit of the result. 
Result so far: 24.0
Subtracting 1420 from 1553 leaves us with 133.
Grab the next digit (9) from the dividend, add it to 133, then carry on: 1339 / 355

On to step 5:
The number 355 fits into 1339 3 times, leaving a remainder of 274.
The next digit of our result is 3. 
Result so far: 243.0
Subtract 1065 from 1339 to get 274.
Take the next digit (7) from the dividend and append it to 274, then repeat: 2747 / 355

Moving on to step 6:
2747 divided by 355 is 7 with a remainder of 262.
Use 7 as the next digit of our solution. 
Result so far: 2437.0
The remainder is 262 after subtracting 2485 from 2747.
Fetch the next digit (1) from the dividend, attach it to 262 and continue: 2621 / 355

Moving on to step 7:
If we divide 2621 by 355, we get 7 and a remainder of 136.
Write down 7 as next digit of the result. 
Result so far: 24377.0
If we subtract 2485 from 2621, we get 136.
Bring next digit (5) of the dividend behind the 136 and repeat the process: 1365 / 355

Moving on to step 8:
355 can be fit into 1365 3 times, resulting in a remainder of 300.
Put 3 as the next digit of the answer. 
Result so far: 243773.0
If we subtract 1065 from 1365, we get 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

On to step 9:
If we divide 3000 by 355, we get 8 and a remainder of 160.
The number 8 becomes the next digit in our result. 
Result so far: 243773.8
Subtract 2840 from 3000 to get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Advancing to step 10:
1600 divided by 355 is 4 with a remainder of 180.
Put 4 as the next digit of the answer. 
Result so far: 243773.84
Subtract 1420 from 1600 to 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.

Step 11:
1800 divided by 355 is 5 with a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 243773.845
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.

Going ahead to step 12:
The number 355 fits into 250 0 times, leaving a remainder of 250.
Write down 0 as next digit of the result. 
Result so far: 243773.845
Subtract 0 from 250 to get 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Let's proceed to step 13:
355 can be fit into 2500 7 times, resulting in a remainder of 15.
Write down 7 as next digit of the result. 
Result so far: 243773.84507
Deduct 2485 from 2500 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 14:
355 can be fit into 150 0 times, resulting in a remainder of 150.
Put 0 as the next digit of the answer. 
Result so far: 243773.84507
If we take 0 away from 150, we end up 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.

Advancing to step 15:
1500 divided by 355 is 4 with a remainder of 80.
Write down 4 as next digit of the result. 
Result so far: 243773.8450704
Subtracting 1420 from 1500 leaves us 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.

Let's proceed to step 16:
800 divided by 355 is 2 with a remainder of 90.
Put 2 as the next digit of the answer. 
Result so far: 243773.84507042
If we take 710 away from 800, we end up 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.

The quotient of the division is 243773.84507042, and the remainder is 9e-08.
