743902 divided by 70 
The aim is to understand the frequency of 70 in 743902.

On to step 1:
70 can be fit into 7 0 times, resulting in a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Take the next digit (4) from the dividend and append it to 7, then repeat: 74 / 70

On to step 2:
The number 70 fits into 74 1 times, leaving a remainder of 4.
The next digit of our result is 1. 
Result so far: 1.0
If we take 70 away from 74, we end up with 4.
Include the next digit (3) from the dividend after 4, then repeat: 43 / 70

Step 3:
43 divided by 70 is 0 with a remainder of 43.
Write down 0 as next digit of the result. 
Result so far: 10.0
The remainder is 43 after subtracting 0 from 43.
Grab the next digit (9) from the dividend, add it to 43, then carry on: 439 / 70

Moving on to step 4:
If we divide 439 by 70, we get 6 and a remainder of 19.
The next digit of our result is 6. 
Result so far: 106.0
If we take 420 away from 439, we end up with 19.
Fetch the next digit (0) from the dividend, attach it to 19 and continue: 190 / 70

On to step 5:
70 goes into 190 2 times with a remainder of 50.
The number 2 becomes the next digit in our result. 
Result so far: 1062.0
If we subtract 140 from 190, we get 50.
Bring next digit (2) of the dividend behind the 50 and repeat the process: 502 / 70

Advancing to step 6:
If we divide 502 by 70, we get 7 and a remainder of 12.
The number 7 becomes the next digit in our result. 
Result so far: 10627.0
Deduct 490 from 502 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 7:
If we divide 120 by 70, we get 1 and a remainder of 50.
Put 1 as the next digit of the answer. 
Result so far: 10627.1
If we take 70 away from 120, we end up 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.

Going ahead to step 8:
500 divided by 70 is 7 with a remainder of 10.
Put 7 as the next digit of the answer. 
Result so far: 10627.17
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.

Moving on to step 9:
70 can be fit into 100 1 times, resulting in a remainder of 30.
Write down 1 as next digit of the result. 
Result so far: 10627.171
If we take 70 away from 100, 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.

Let's proceed to step 10:
300 divided by 70 is 4 with a remainder of 20.
The number 4 becomes the next digit in our result. 
Result so far: 10627.1714
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 11:
200 divided by 70 is 2 with a remainder of 60.
Put 2 as the next digit of the answer. 
Result so far: 10627.17142
Subtracting 140 from 200 leaves us with 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 12:
The number 70 fits into 600 8 times, leaving a remainder of 40.
Write down 8 as next digit of the result. 
Result so far: 10627.171428
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.

Going ahead to step 13:
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: 10627.1714285
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.

Going ahead to step 14:
If we divide 500 by 70, we get 7 and a remainder of 10.
The next digit of our result is 7. 
Result so far: 10627.17142857
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.

The quotient of the division is 10627.17142857, and the remainder is 1e-08.
