758640 ÷ 70 
The aim is to understand the frequency of 70 in 758640.

Let's proceed to step 1:
70 goes into 7 0 times with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Take the next digit (5) from the dividend and append it to 7, then repeat: 75 / 70

Moving on to step 2:
70 can be fit into 75 1 times, resulting in a remainder of 5.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 70 from 75 leaves us with 5.
Bring next digit (8) of the dividend behind the 5 and repeat the process: 58 / 70

Step 3:
58 divided by 70 is 0 with a remainder of 58.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
If we subtract 0 from 58, we get 58.
Fetch the next digit (6) from the dividend, attach it to 58 and continue: 586 / 70

On to step 4:
If we divide 586 by 70, we get 8 and a remainder of 26.
Record the quotient 8 as the next digit in the result. 
Result so far: 108.0
If we subtract 560 from 586, we get 26.
Append the next digit (4) from the dividend to 26 and continue with: 264 / 70

Moving on to step 5:
If we divide 264 by 70, we get 3 and a remainder of 54.
The number 3 becomes the next digit in our result. 
Result so far: 1083.0
The remainder is 54 after subtracting 210 from 264.
Fetch the next digit (0) from the dividend, attach it to 54 and continue: 540 / 70

Let's proceed to step 6:
540 divided by 70 is 7 with a remainder of 50.
The number 7 becomes the next digit in our result. 
Result so far: 10837.0
Subtract 490 from 540 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.

Step 7:
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: 10837.7
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.

Advancing to step 8:
70 goes into 100 1 times with a remainder of 30.
Record the quotient 1 as the next digit in the result. 
Result so far: 10837.71
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.

On to step 9:
70 can be fit into 300 4 times, resulting in a remainder of 20.
Put 4 as the next digit of the answer. 
Result so far: 10837.714
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.

Step 10:
When dividing 200 by 70, we get 2 with a remainder of 60.
Use 2 as the next digit of our solution. 
Result so far: 10837.7142
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.

Advancing to step 11:
If we divide 600 by 70, we get 8 and a remainder of 40.
Record the quotient 8 as the next digit in the result. 
Result so far: 10837.71428
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.

On to step 12:
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: 10837.714285
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.

Moving on to step 13:
When dividing 500 by 70, we get 7 with a remainder of 10.
Use 7 as the next digit of our solution. 
Result so far: 10837.7142857
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.

Advancing to step 14:
When dividing 100 by 70, we get 1 with a remainder of 30.
The number 1 becomes the next digit in our result. 
Result so far: 10837.71428571
Subtracting 70 from 100 leaves us 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.

The quotient of the division is 10837.71428571, and the remainder is 3e-08.
