845575 ÷ 70 
The aim is to understand the frequency of 70 in 845575.

Let's proceed to step 1:
8 divided by 70 is 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Bring next digit (4) of the dividend behind the 8 and repeat the process: 84 / 70

On to step 2:
84 divided by 70 is 1 with a remainder of 14.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 70 away from 84, we end up with 14.
Append the next digit (5) from the dividend to 14 and continue with: 145 / 70

Going ahead to step 3:
When dividing 145 by 70, we get 2 with a remainder of 5.
Use 2 as the next digit of our solution. 
Result so far: 12.0
Subtract 140 from 145 to get 5.
Take the next digit (5) from the dividend and append it to 5, then repeat: 55 / 70

On to step 4:
70 can be fit into 55 0 times, resulting in a remainder of 55.
The next digit of our result is 0. 
Result so far: 120.0
Subtracting 0 from 55 leaves us with 55.
Take the next digit (7) from the dividend and append it to 55, then repeat: 557 / 70

Step 5:
The number 70 fits into 557 7 times, leaving a remainder of 67.
Write down 7 as next digit of the result. 
Result so far: 1207.0
The remainder is 67 after subtracting 490 from 557.
Append the next digit (5) from the dividend to 67 and continue with: 675 / 70

On to step 6:
70 can be fit into 675 9 times, resulting in a remainder of 45.
Record the quotient 9 as the next digit in the result. 
Result so far: 12079.0
Subtract 630 from 675 to get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

On to step 7:
If we divide 450 by 70, we get 6 and a remainder of 30.
Write down 6 as next digit of the result. 
Result so far: 12079.6
If we take 420 away from 450, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 8:
70 goes into 300 4 times with a remainder of 20.
Record the quotient 4 as the next digit in the result. 
Result so far: 12079.64
Subtract 280 from 300 to 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.

Let's proceed to step 9:
When dividing 200 by 70, we get 2 with a remainder of 60.
Record the quotient 2 as the next digit in the result. 
Result so far: 12079.642
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.

Going ahead to step 10:
600 divided by 70 is 8 with a remainder of 40.
The number 8 becomes the next digit in our result. 
Result so far: 12079.6428
If we take 560 away from 600, we end up 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.

On to step 11:
If we divide 400 by 70, we get 5 and a remainder of 50.
Record the quotient 5 as the next digit in the result. 
Result so far: 12079.64285
The remainder is 50 after subtracting 350 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 12:
70 can be fit into 500 7 times, resulting in a remainder of 10.
Use 7 as the next digit of our solution. 
Result so far: 12079.642857
Subtract 490 from 500 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 13:
When dividing 100 by 70, we get 1 with a remainder of 30.
Record the quotient 1 as the next digit in the result. 
Result so far: 12079.6428571
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.

Advancing to step 14:
70 can be fit into 300 4 times, resulting in a remainder of 20.
Put 4 as the next digit of the answer. 
Result so far: 12079.64285714
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.

Our division results in 12079.64285714 with a remaining 2e-08.
