69078138 ÷ 70 
The aim is to understand the frequency of 70 in 69078138.

Going ahead to step 1:
6 divided by 70 is 0 with 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.
Include the next digit (9) from the dividend after 6, then repeat: 69 / 70

On to step 2:
If we divide 69 by 70, we get 0 and a remainder of 69.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 69 to get 69.
Fetch the next digit (0) from the dividend, attach it to 69 and continue: 690 / 70

On to step 3:
The number 70 fits into 690 9 times, leaving a remainder of 60.
The next digit of our result is 9. 
Result so far: 9.0
Deduct 630 from 690 and we're left with 60.
Bring next digit (7) of the dividend behind the 60 and repeat the process: 607 / 70

Step 4:
70 goes into 607 8 times with a remainder of 47.
Put 8 as the next digit of the answer. 
Result so far: 98.0
Deduct 560 from 607 and we're left with 47.
Fetch the next digit (8) from the dividend, attach it to 47 and continue: 478 / 70

Going ahead to step 5:
70 goes into 478 6 times with a remainder of 58.
Put 6 as the next digit of the answer. 
Result so far: 986.0
If we take 420 away from 478, we end up with 58.
Grab the next digit (1) from the dividend, add it to 58, then carry on: 581 / 70

On to step 6:
70 goes into 581 8 times with a remainder of 21.
The next digit of our result is 8. 
Result so far: 9868.0
The remainder is 21 after subtracting 560 from 581.
Fetch the next digit (3) from the dividend, attach it to 21 and continue: 213 / 70

Advancing to step 7:
If we divide 213 by 70, we get 3 and a remainder of 3.
Record the quotient 3 as the next digit in the result. 
Result so far: 98683.0
Subtracting 210 from 213 leaves us with 3.
Fetch the next digit (8) from the dividend, attach it to 3 and continue: 38 / 70

Let's proceed to step 8:
38 divided by 70 is 0 with a remainder of 38.
Write down 0 as next digit of the result. 
Result so far: 986830.0
The remainder is 38 after subtracting 0 from 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Moving on to step 9:
380 divided by 70 is 5 with a remainder of 30.
Write down 5 as next digit of the result. 
Result so far: 986830.5
If we take 350 away from 380, we end up 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.

Step 10:
300 divided by 70 is 4 with a remainder of 20.
The number 4 becomes the next digit in our result. 
Result so far: 986830.54
The remainder is 20 after subtracting 280 from 300.
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.
Record the quotient 2 as the next digit in the result. 
Result so far: 986830.542
If we subtract 140 from 200, we 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.

Going ahead to step 12:
600 divided by 70 is 8 with a remainder of 40.
Use 8 as the next digit of our solution. 
Result so far: 986830.5428
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 13:
When dividing 400 by 70, we get 5 with a remainder of 50.
Record the quotient 5 as the next digit in the result. 
Result so far: 986830.54285
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 14:
When dividing 500 by 70, we get 7 with a remainder of 10.
The number 7 becomes the next digit in our result. 
Result so far: 986830.542857
If we take 490 away from 500, 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.

Moving on to step 15:
70 can be fit into 100 1 times, resulting in a remainder of 30.
The number 1 becomes the next digit in our result. 
Result so far: 986830.5428571
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.

Let's proceed to step 16:
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: 986830.54285714
The remainder is 20 after subtracting 280 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

In conclusion, the division gives 986830.54285714 with a balance of 2e-08.
