Let's divide 684551 by 70
The aim is to understand the frequency of 70 in 684551.

Moving on to step 1:
The number 70 fits into 6 0 times, leaving a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Bring next digit (8) of the dividend behind the 6 and repeat the process: 68 / 70

Moving on to step 2:
The number 70 fits into 68 0 times, leaving a remainder of 68.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 68, we get 68.
Include the next digit (4) from the dividend after 68, then repeat: 684 / 70

On to step 3:
70 goes into 684 9 times with a remainder of 54.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
The remainder is 54 after subtracting 630 from 684.
Grab the next digit (5) from the dividend, add it to 54, then carry on: 545 / 70

Going ahead to step 4:
70 can be fit into 545 7 times, resulting in a remainder of 55.
The next digit of our result is 7. 
Result so far: 97.0
If we take 490 away from 545, we end up with 55.
Grab the next digit (5) from the dividend, add it to 55, then carry on: 555 / 70

Step 5:
555 divided by 70 is 7 with a remainder of 65.
Put 7 as the next digit of the answer. 
Result so far: 977.0
Subtracting 490 from 555 leaves us with 65.
Bring next digit (1) of the dividend behind the 65 and repeat the process: 651 / 70

Step 6:
When dividing 651 by 70, we get 9 with a remainder of 21.
Put 9 as the next digit of the answer. 
Result so far: 9779.0
Deduct 630 from 651 and we're left with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Step 7:
70 can be fit into 210 3 times, resulting in a remainder of 0.
The number 3 becomes the next digit in our result. 
Result so far: 9779.3
Subtract 210 from 210 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 8:
70 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 9779.3
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 9:
0 divided by 70 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 9779.3
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 9779.3 with a remaining 0.0.
