73211 ÷ 70 
The aim is to understand the frequency of 70 in 73211.

Step 1:
The number 70 fits into 7 0 times, leaving a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Bring next digit (3) of the dividend behind the 7 and repeat the process: 73 / 70

Step 2:
70 can be fit into 73 1 times, resulting in a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 70 away from 73, we end up with 3.
Append the next digit (2) from the dividend to 3 and continue with: 32 / 70

Going ahead to step 3:
32 divided by 70 is 0 with a remainder of 32.
The next digit of our result is 0. 
Result so far: 10.0
The remainder is 32 after subtracting 0 from 32.
Fetch the next digit (1) from the dividend, attach it to 32 and continue: 321 / 70

Moving on to step 4:
If we divide 321 by 70, we get 4 and a remainder of 41.
The next digit of our result is 4. 
Result so far: 104.0
Subtracting 280 from 321 leaves us with 41.
Bring next digit (1) of the dividend behind the 41 and repeat the process: 411 / 70

Moving on to step 5:
If we divide 411 by 70, we get 5 and a remainder of 61.
Use 5 as the next digit of our solution. 
Result so far: 1045.0
If we take 350 away from 411, we end up with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Advancing to step 6:
70 can be fit into 610 8 times, resulting in a remainder of 50.
Put 8 as the next digit of the answer. 
Result so far: 1045.8
If we subtract 560 from 610, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 7:
500 divided by 70 is 7 with a remainder of 10.
Use 7 as the next digit of our solution. 
Result so far: 1045.87
Deduct 490 from 500 and we're left 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.

Step 8:
When dividing 100 by 70, we get 1 with a remainder of 30.
The next digit of our result is 1. 
Result so far: 1045.871
Subtracting 70 from 100 leaves us 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.

On to step 9:
70 can be fit into 300 4 times, resulting in a remainder of 20.
The next digit of our result is 4. 
Result so far: 1045.8714
The remainder is 20 after subtracting 280 from 300.
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 10:
200 divided by 70 is 2 with a remainder of 60.
Use 2 as the next digit of our solution. 
Result so far: 1045.87142
If we subtract 140 from 200, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 11:
When dividing 600 by 70, we get 8 with a remainder of 40.
The number 8 becomes the next digit in our result. 
Result so far: 1045.871428
If we subtract 560 from 600, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 12:
70 can be fit into 400 5 times, resulting in a remainder of 50.
Record the quotient 5 as the next digit in the result. 
Result so far: 1045.8714285
If we subtract 350 from 400, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 13:
If we divide 500 by 70, we get 7 and a remainder of 10.
Write down 7 as next digit of the result. 
Result so far: 1045.87142857
If we take 490 away from 500, we end up 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.

The final result is 1045.87142857 with a remainder of 1e-08.
