We divide 705243 by 86
The aim is to understand the frequency of 86 in 705243.

Step 1:
If we divide 7 by 86, we get 0 and a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Take the next digit (0) from the dividend and append it to 7, then repeat: 70 / 86

Going ahead to step 2:
86 can be fit into 70 0 times, resulting in a remainder of 70.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 70, we get 70.
Append the next digit (5) from the dividend to 70 and continue with: 705 / 86

Let's proceed to step 3:
If we divide 705 by 86, we get 8 and a remainder of 17.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Subtract 688 from 705 to get 17.
Grab the next digit (2) from the dividend, add it to 17, then carry on: 172 / 86

Advancing to step 4:
The number 86 fits into 172 2 times, leaving a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 82.0
If we subtract 172 from 172, we get 0.
Append the next digit (4) from the dividend to 0 and continue with: 4 / 86

Moving on to step 5:
4 divided by 86 is 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 820.0
If we subtract 0 from 4, we get 4.
Append the next digit (3) from the dividend to 4 and continue with: 43 / 86

Let's proceed to step 6:
86 goes into 43 0 times with a remainder of 43.
Write down 0 as next digit of the result. 
Result so far: 8200.0
The remainder is 43 after subtracting 0 from 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Advancing to step 7:
The number 86 fits into 430 5 times, leaving a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 8200.5
The remainder is 0 after subtracting 430 from 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 8:
When dividing 0 by 86, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 8200.5
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 9:
86 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 8200.5
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 8200.5, and the remainder is 0.0.
