620100 divided by 70 
The aim is to understand the frequency of 70 in 620100.

Going ahead to step 1:
6 divided by 70 is 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Grab the next digit (2) from the dividend, add it to 6, then carry on: 62 / 70

Going ahead to step 2:
70 goes into 62 0 times with a remainder of 62.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 62 leaves us with 62.
Include the next digit (0) from the dividend after 62, then repeat: 620 / 70

Going ahead to step 3:
If we divide 620 by 70, we get 8 and a remainder of 60.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Deduct 560 from 620 and we're left with 60.
Include the next digit (1) from the dividend after 60, then repeat: 601 / 70

Going ahead to step 4:
When dividing 601 by 70, we get 8 with a remainder of 41.
Use 8 as the next digit of our solution. 
Result so far: 88.0
The remainder is 41 after subtracting 560 from 601.
Bring next digit (0) of the dividend behind the 41 and repeat the process: 410 / 70

On to step 5:
70 can be fit into 410 5 times, resulting in a remainder of 60.
Put 5 as the next digit of the answer. 
Result so far: 885.0
Subtract 350 from 410 to get 60.
Grab the next digit (0) from the dividend, add it to 60, then carry on: 600 / 70

On to step 6:
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: 8858.0
If we subtract 560 from 600, we 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.

Let's proceed to step 7:
If we divide 400 by 70, we get 5 and a remainder of 50.
Put 5 as the next digit of the answer. 
Result so far: 8858.5
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.

Going ahead to step 8:
70 can be fit into 500 7 times, resulting in a remainder of 10.
Write down 7 as next digit of the result. 
Result so far: 8858.57
Subtracting 490 from 500 leaves us 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.

On to step 9:
100 divided by 70 is 1 with a remainder of 30.
Use 1 as the next digit of our solution. 
Result so far: 8858.571
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 10:
70 goes into 300 4 times with a remainder of 20.
Use 4 as the next digit of our solution. 
Result so far: 8858.5714
Deduct 280 from 300 and we're left 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.

Moving on to step 11:
70 goes into 200 2 times with a remainder of 60.
Record the quotient 2 as the next digit in the result. 
Result so far: 8858.57142
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.

On to step 12:
The number 70 fits into 600 8 times, leaving a remainder of 40.
Write down 8 as next digit of the result. 
Result so far: 8858.571428
Subtracting 560 from 600 leaves us 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.

Going ahead to step 13:
70 goes into 400 5 times with a remainder of 50.
Use 5 as the next digit of our solution. 
Result so far: 8858.5714285
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 can be fit into 500 7 times, resulting in a remainder of 10.
Use 7 as the next digit of our solution. 
Result so far: 8858.57142857
If we subtract 490 from 500, we 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.

In conclusion, the division gives 8858.57142857 with a balance of 1e-08.
