Let's divide 330891 by 70
The aim is to understand the frequency of 70 in 330891.

On to step 1:
70 can be fit into 3 0 times, resulting in a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Include the next digit (3) from the dividend after 3, then repeat: 33 / 70

Going ahead to step 2:
The number 70 fits into 33 0 times, leaving a remainder of 33.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 33 and we're left with 33.
Bring next digit (0) of the dividend behind the 33 and repeat the process: 330 / 70

Advancing to step 3:
The number 70 fits into 330 4 times, leaving a remainder of 50.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Subtract 280 from 330 to get 50.
Grab the next digit (8) from the dividend, add it to 50, then carry on: 508 / 70

Advancing to step 4:
70 can be fit into 508 7 times, resulting in a remainder of 18.
Use 7 as the next digit of our solution. 
Result so far: 47.0
Subtracting 490 from 508 leaves us with 18.
Grab the next digit (9) from the dividend, add it to 18, then carry on: 189 / 70

Step 5:
70 can be fit into 189 2 times, resulting in a remainder of 49.
Record the quotient 2 as the next digit in the result. 
Result so far: 472.0
If we take 140 away from 189, we end up with 49.
Take the next digit (1) from the dividend and append it to 49, then repeat: 491 / 70

Going ahead to step 6:
The number 70 fits into 491 7 times, leaving a remainder of 1.
Record the quotient 7 as the next digit in the result. 
Result so far: 4727.0
The remainder is 1 after subtracting 490 from 491.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 7:
If we divide 10 by 70, we get 0 and a remainder of 10.
The next digit of our result is 0. 
Result so far: 4727.0
Subtract 0 from 10 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.

Going ahead to step 8:
If we divide 100 by 70, we get 1 and a remainder of 30.
Use 1 as the next digit of our solution. 
Result so far: 4727.01
If we subtract 70 from 100, we 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 9:
If we divide 300 by 70, we get 4 and a remainder of 20.
Use 4 as the next digit of our solution. 
Result so far: 4727.014
Subtracting 280 from 300 leaves us 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.

Let's proceed to step 10:
200 divided by 70 is 2 with a remainder of 60.
Record the quotient 2 as the next digit in the result. 
Result so far: 4727.0142
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.

Step 11:
The number 70 fits into 600 8 times, leaving a remainder of 40.
Record the quotient 8 as the next digit in the result. 
Result so far: 4727.01428
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 12:
70 can be fit into 400 5 times, resulting in a remainder of 50.
Use 5 as the next digit of our solution. 
Result so far: 4727.014285
If we take 350 away from 400, 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.

Advancing to step 13:
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: 4727.0142857
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.

Advancing to step 14:
70 goes into 100 1 times with a remainder of 30.
Record the quotient 1 as the next digit in the result. 
Result so far: 4727.01428571
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.

The final outcome is 4727.01428571, with a leftover of 3e-08.
