378342 divided by 70 
The aim is to understand the frequency of 70 in 378342.

Let's proceed to step 1:
The number 70 fits into 3 0 times, leaving a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Append the next digit (7) from the dividend to 3 and continue with: 37 / 70

On to step 2:
70 goes into 37 0 times with a remainder of 37.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 37 leaves us with 37.
Append the next digit (8) from the dividend to 37 and continue with: 378 / 70

Step 3:
70 goes into 378 5 times with a remainder of 28.
Write down 5 as next digit of the result. 
Result so far: 5.0
Subtracting 350 from 378 leaves us with 28.
Fetch the next digit (3) from the dividend, attach it to 28 and continue: 283 / 70

Moving on to step 4:
70 can be fit into 283 4 times, resulting in a remainder of 3.
Put 4 as the next digit of the answer. 
Result so far: 54.0
Subtracting 280 from 283 leaves us with 3.
Bring next digit (4) of the dividend behind the 3 and repeat the process: 34 / 70

Going ahead to step 5:
When dividing 34 by 70, we get 0 with a remainder of 34.
Record the quotient 0 as the next digit in the result. 
Result so far: 540.0
The remainder is 34 after subtracting 0 from 34.
Append the next digit (2) from the dividend to 34 and continue with: 342 / 70

Going ahead to step 6:
70 goes into 342 4 times with a remainder of 62.
The next digit of our result is 4. 
Result so far: 5404.0
If we take 280 away from 342, we end up with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Step 7:
70 goes into 620 8 times with a remainder of 60.
Put 8 as the next digit of the answer. 
Result so far: 5404.8
If we take 560 away from 620, we end up 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.

Let's proceed to step 8:
The number 70 fits into 600 8 times, leaving a remainder of 40.
Put 8 as the next digit of the answer. 
Result so far: 5404.88
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.

The quotient of the division is 5404.88, and the remainder is 0.04.
