990197 ÷ 70 
The aim is to understand the frequency of 70 in 990197.

Step 1:
If we divide 9 by 70, we get 0 and a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Fetch the next digit (9) from the dividend, attach it to 9 and continue: 99 / 70

Advancing to step 2:
70 can be fit into 99 1 times, resulting in a remainder of 29.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 70 from 99, we get 29.
Take the next digit (0) from the dividend and append it to 29, then repeat: 290 / 70

Step 3:
When dividing 290 by 70, we get 4 with a remainder of 10.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
Subtracting 280 from 290 leaves us with 10.
Append the next digit (1) from the dividend to 10 and continue with: 101 / 70

Let's proceed to step 4:
70 goes into 101 1 times with a remainder of 31.
Use 1 as the next digit of our solution. 
Result so far: 141.0
Subtract 70 from 101 to get 31.
Grab the next digit (9) from the dividend, add it to 31, then carry on: 319 / 70

Advancing to step 5:
When dividing 319 by 70, we get 4 with a remainder of 39.
Put 4 as the next digit of the answer. 
Result so far: 1414.0
Deduct 280 from 319 and we're left with 39.
Append the next digit (7) from the dividend to 39 and continue with: 397 / 70

Advancing to step 6:
397 divided by 70 is 5 with a remainder of 47.
Use 5 as the next digit of our solution. 
Result so far: 14145.0
Subtracting 350 from 397 leaves us with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Step 7:
470 divided by 70 is 6 with a remainder of 50.
Put 6 as the next digit of the answer. 
Result so far: 14145.6
Deduct 420 from 470 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.

Advancing to step 8:
The number 70 fits into 500 7 times, leaving a remainder of 10.
The number 7 becomes the next digit in our result. 
Result so far: 14145.67
The remainder is 10 after subtracting 490 from 500.
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 9:
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: 14145.671
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.

Advancing to step 10:
70 goes into 300 4 times with a remainder of 20.
The number 4 becomes the next digit in our result. 
Result so far: 14145.6714
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.

Going ahead to step 11:
200 divided by 70 is 2 with a remainder of 60.
The number 2 becomes the next digit in our result. 
Result so far: 14145.67142
Subtract 140 from 200 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 12:
If we divide 600 by 70, we get 8 and a remainder of 40.
Write down 8 as next digit of the result. 
Result so far: 14145.671428
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.

Moving on to step 13:
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: 14145.6714285
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.

Step 14:
70 goes into 500 7 times with a remainder of 10.
Record the quotient 7 as the next digit in the result. 
Result so far: 14145.67142857
Subtract 490 from 500 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.

After the division, we end up with 14145.67142857 and a remainder of 1e-08.
