We're dividing 661826 by 70 
The aim is to understand the frequency of 70 in 661826.

Going ahead to step 1:
70 can be fit into 6 0 times, resulting in a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 70

Going ahead to step 2:
If we divide 66 by 70, we get 0 and a remainder of 66.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 66, we get 66.
Append the next digit (1) from the dividend to 66 and continue with: 661 / 70

Step 3:
When dividing 661 by 70, we get 9 with a remainder of 31.
Use 9 as the next digit of our solution. 
Result so far: 9.0
Deduct 630 from 661 and we're left with 31.
Append the next digit (8) from the dividend to 31 and continue with: 318 / 70

Step 4:
70 can be fit into 318 4 times, resulting in a remainder of 38.
Use 4 as the next digit of our solution. 
Result so far: 94.0
Deduct 280 from 318 and we're left with 38.
Grab the next digit (2) from the dividend, add it to 38, then carry on: 382 / 70

On to step 5:
When dividing 382 by 70, we get 5 with a remainder of 32.
Put 5 as the next digit of the answer. 
Result so far: 945.0
If we take 350 away from 382, we end up with 32.
Fetch the next digit (6) from the dividend, attach it to 32 and continue: 326 / 70

Going ahead to step 6:
The number 70 fits into 326 4 times, leaving a remainder of 46.
The number 4 becomes the next digit in our result. 
Result so far: 9454.0
Subtract 280 from 326 to get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Let's proceed to step 7:
If we divide 460 by 70, we get 6 and a remainder of 40.
Use 6 as the next digit of our solution. 
Result so far: 9454.6
Deduct 420 from 460 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.

Advancing to step 8:
When dividing 400 by 70, we get 5 with a remainder of 50.
The number 5 becomes the next digit in our result. 
Result so far: 9454.65
Deduct 350 from 400 and we're left 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.

Moving on to step 9:
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: 9454.657
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.

Going ahead to step 10:
When dividing 100 by 70, we get 1 with a remainder of 30.
The next digit of our result is 1. 
Result so far: 9454.6571
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.

On to step 11:
300 divided by 70 is 4 with a remainder of 20.
Put 4 as the next digit of the answer. 
Result so far: 9454.65714
If we subtract 280 from 300, we 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.

Moving on to step 12:
70 goes into 200 2 times with a remainder of 60.
The number 2 becomes the next digit in our result. 
Result so far: 9454.657142
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.

Moving on to step 13:
70 goes into 600 8 times with a remainder of 40.
The next digit of our result is 8. 
Result so far: 9454.6571428
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.

Step 14:
70 goes into 400 5 times with a remainder of 50.
Record the quotient 5 as the next digit in the result. 
Result so far: 9454.65714285
Subtract 350 from 400 to 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.

In conclusion, the division gives 9454.65714285 with a balance of 5e-08.
