557054 ÷ 70 
The aim is to understand the frequency of 70 in 557054.

On to step 1:
70 goes into 5 0 times with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Append the next digit (5) from the dividend to 5 and continue with: 55 / 70

Going ahead to step 2:
70 goes into 55 0 times with a remainder of 55.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 55 to get 55.
Take the next digit (7) from the dividend and append it to 55, then repeat: 557 / 70

On to step 3:
70 can be fit into 557 7 times, resulting in a remainder of 67.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Subtract 490 from 557 to get 67.
Fetch the next digit (0) from the dividend, attach it to 67 and continue: 670 / 70

Going ahead to step 4:
70 goes into 670 9 times with a remainder of 40.
Record the quotient 9 as the next digit in the result. 
Result so far: 79.0
Subtract 630 from 670 to get 40.
Append the next digit (5) from the dividend to 40 and continue with: 405 / 70

On to step 5:
405 divided by 70 is 5 with a remainder of 55.
Use 5 as the next digit of our solution. 
Result so far: 795.0
The remainder is 55 after subtracting 350 from 405.
Take the next digit (4) from the dividend and append it to 55, then repeat: 554 / 70

Moving on to step 6:
When dividing 554 by 70, we get 7 with a remainder of 64.
Write down 7 as next digit of the result. 
Result so far: 7957.0
If we take 490 away from 554, we end up with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Advancing to step 7:
The number 70 fits into 640 9 times, leaving a remainder of 10.
The next digit of our result is 9. 
Result so far: 7957.9
Subtract 630 from 640 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.

Let's proceed to step 8:
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: 7957.91
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.

Advancing to step 9:
The number 70 fits into 300 4 times, leaving a remainder of 20.
The next digit of our result is 4. 
Result so far: 7957.914
If we take 280 away from 300, we end up 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 10:
70 can be fit into 200 2 times, resulting in a remainder of 60.
Write down 2 as next digit of the result. 
Result so far: 7957.9142
Subtracting 140 from 200 leaves us 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.

Going ahead to step 11:
If we divide 600 by 70, we get 8 and a remainder of 40.
Use 8 as the next digit of our solution. 
Result so far: 7957.91428
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.

Advancing to step 12:
400 divided by 70 is 5 with a remainder of 50.
Put 5 as the next digit of the answer. 
Result so far: 7957.914285
If we subtract 350 from 400, we 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.

Let's proceed to step 13:
If we divide 500 by 70, we get 7 and a remainder of 10.
The number 7 becomes the next digit in our result. 
Result so far: 7957.9142857
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.

Let's proceed to step 14:
70 can be fit into 100 1 times, resulting in a remainder of 30.
Write down 1 as next digit of the result. 
Result so far: 7957.91428571
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.

The final outcome is 7957.91428571, with a leftover of 3e-08.
