We're dividing 539861 by 70 
The aim is to understand the frequency of 70 in 539861.

Let's proceed to step 1:
If we divide 5 by 70, we get 0 and a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Take the next digit (3) from the dividend and append it to 5, then repeat: 53 / 70

On to step 2:
If we divide 53 by 70, we get 0 and a remainder of 53.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 53 leaves us with 53.
Fetch the next digit (9) from the dividend, attach it to 53 and continue: 539 / 70

Going ahead to step 3:
70 goes into 539 7 times with a remainder of 49.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
If we take 490 away from 539, we end up with 49.
Take the next digit (8) from the dividend and append it to 49, then repeat: 498 / 70

Step 4:
70 can be fit into 498 7 times, resulting in a remainder of 8.
The number 7 becomes the next digit in our result. 
Result so far: 77.0
The remainder is 8 after subtracting 490 from 498.
Bring next digit (6) of the dividend behind the 8 and repeat the process: 86 / 70

On to step 5:
86 divided by 70 is 1 with a remainder of 16.
The number 1 becomes the next digit in our result. 
Result so far: 771.0
Deduct 70 from 86 and we're left with 16.
Grab the next digit (1) from the dividend, add it to 16, then carry on: 161 / 70

On to step 6:
70 goes into 161 2 times with a remainder of 21.
Use 2 as the next digit of our solution. 
Result so far: 7712.0
The remainder is 21 after subtracting 140 from 161.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Going ahead to step 7:
70 can be fit into 210 3 times, resulting in a remainder of 0.
The next digit of our result is 3. 
Result so far: 7712.3
If we take 210 away from 210, we end up 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.

Advancing to step 8:
If we divide 0 by 70, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 7712.3
Subtracting 0 from 0 leaves us 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.

Going ahead to step 9:
If we divide 0 by 70, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 7712.3
Subtract 0 from 0 to get 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 7712.3, and the remainder is 0.0.
