We divide 378211 by 70
The aim is to understand the frequency of 70 in 378211.

On to step 1:
If we divide 3 by 70, we get 0 and a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Take the next digit (7) from the dividend and append it to 3, then repeat: 37 / 70

Advancing to step 2:
37 divided by 70 is 0 with a remainder of 37.
Put 0 as the next digit of the answer. 
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

Let's proceed to step 3:
70 goes into 378 5 times with a remainder of 28.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Subtracting 350 from 378 leaves us with 28.
Grab the next digit (2) from the dividend, add it to 28, then carry on: 282 / 70

On to step 4:
70 goes into 282 4 times with a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 54.0
Subtracting 280 from 282 leaves us with 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 70

Let's proceed to step 5:
The number 70 fits into 21 0 times, leaving a remainder of 21.
Use 0 as the next digit of our solution. 
Result so far: 540.0
The remainder is 21 after subtracting 0 from 21.
Include the next digit (1) from the dividend after 21, then repeat: 211 / 70

Advancing to step 6:
70 goes into 211 3 times with a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 5403.0
The remainder is 1 after subtracting 210 from 211.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 7:
70 can be fit into 10 0 times, resulting in a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 5403.0
If we take 0 away from 10, 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.

Step 8:
70 can be fit into 100 1 times, resulting in a remainder of 30.
Record the quotient 1 as the next digit in the result. 
Result so far: 5403.01
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.

Moving on to step 9:
300 divided by 70 is 4 with a remainder of 20.
Record the quotient 4 as the next digit in the result. 
Result so far: 5403.014
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.

Going ahead to step 10:
When dividing 200 by 70, we get 2 with a remainder of 60.
The next digit of our result is 2. 
Result so far: 5403.0142
If we take 140 away from 200, 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.

Advancing to step 11:
600 divided by 70 is 8 with a remainder of 40.
Write down 8 as next digit of the result. 
Result so far: 5403.01428
Subtract 560 from 600 to 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.

Going ahead 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: 5403.014285
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 13:
70 can be fit into 500 7 times, resulting in a remainder of 10.
Put 7 as the next digit of the answer. 
Result so far: 5403.0142857
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.

Step 14:
The number 70 fits into 100 1 times, leaving a remainder of 30.
Put 1 as the next digit of the answer. 
Result so far: 5403.01428571
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.

Our division results in 5403.01428571 with a remaining 3e-08.
