We look at the division of 545548 by 70 
The aim is to understand the frequency of 70 in 545548.

On to step 1:
70 can be fit into 5 0 times, resulting in a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Append the next digit (4) from the dividend to 5 and continue with: 54 / 70

Step 2:
The number 70 fits into 54 0 times, leaving a remainder of 54.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 54 to get 54.
Grab the next digit (5) from the dividend, add it to 54, then carry on: 545 / 70

Going ahead to step 3:
70 can be fit into 545 7 times, resulting in a remainder of 55.
Write down 7 as next digit of the result. 
Result so far: 7.0
Deduct 490 from 545 and we're left with 55.
Fetch the next digit (5) from the dividend, attach it to 55 and continue: 555 / 70

Advancing to step 4:
If we divide 555 by 70, we get 7 and a remainder of 65.
Put 7 as the next digit of the answer. 
Result so far: 77.0
Subtracting 490 from 555 leaves us with 65.
Append the next digit (4) from the dividend to 65 and continue with: 654 / 70

On to step 5:
70 goes into 654 9 times with a remainder of 24.
Put 9 as the next digit of the answer. 
Result so far: 779.0
If we take 630 away from 654, we end up with 24.
Grab the next digit (8) from the dividend, add it to 24, then carry on: 248 / 70

Going ahead to step 6:
70 goes into 248 3 times with a remainder of 38.
Write down 3 as next digit of the result. 
Result so far: 7793.0
The remainder is 38 after subtracting 210 from 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 7:
If we divide 380 by 70, we get 5 and a remainder of 30.
The number 5 becomes the next digit in our result. 
Result so far: 7793.5
Subtract 350 from 380 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 8:
70 goes into 300 4 times with a remainder of 20.
Put 4 as the next digit of the answer. 
Result so far: 7793.54
Deduct 280 from 300 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 9:
The number 70 fits into 200 2 times, leaving a remainder of 60.
Write down 2 as next digit of the result. 
Result so far: 7793.542
The remainder is 60 after subtracting 140 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 10:
When dividing 600 by 70, we get 8 with a remainder of 40.
Write down 8 as next digit of the result. 
Result so far: 7793.5428
Deduct 560 from 600 and we're left 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 11:
The number 70 fits into 400 5 times, leaving a remainder of 50.
Record the quotient 5 as the next digit in the result. 
Result so far: 7793.54285
Subtracting 350 from 400 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 12:
The number 70 fits into 500 7 times, leaving a remainder of 10.
Record the quotient 7 as the next digit in the result. 
Result so far: 7793.542857
Subtracting 490 from 500 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 13:
If we divide 100 by 70, we get 1 and a remainder of 30.
Write down 1 as next digit of the result. 
Result so far: 7793.5428571
Subtract 70 from 100 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 14:
70 goes into 300 4 times with a remainder of 20.
The next digit of our result is 4. 
Result so far: 7793.54285714
If we subtract 280 from 300, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The quotient of the division is 7793.54285714, and the remainder is 2e-08.
