Let's divide 70464161 by 210
The aim is to understand the frequency of 210 in 70464161.

Going ahead to step 1:
The number 210 fits into 7 0 times, leaving a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Append the next digit (0) from the dividend to 7 and continue with: 70 / 210

Advancing to step 2:
70 divided by 210 is 0 with a remainder of 70.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 70 and we're left with 70.
Bring next digit (4) of the dividend behind the 70 and repeat the process: 704 / 210

Advancing to step 3:
The number 210 fits into 704 3 times, leaving a remainder of 74.
The next digit of our result is 3. 
Result so far: 3.0
Deduct 630 from 704 and we're left with 74.
Bring next digit (6) of the dividend behind the 74 and repeat the process: 746 / 210

Step 4:
If we divide 746 by 210, we get 3 and a remainder of 116.
Use 3 as the next digit of our solution. 
Result so far: 33.0
If we subtract 630 from 746, we get 116.
Grab the next digit (4) from the dividend, add it to 116, then carry on: 1164 / 210

Advancing to step 5:
When dividing 1164 by 210, we get 5 with a remainder of 114.
Write down 5 as next digit of the result. 
Result so far: 335.0
The remainder is 114 after subtracting 1050 from 1164.
Append the next digit (1) from the dividend to 114 and continue with: 1141 / 210

Step 6:
The number 210 fits into 1141 5 times, leaving a remainder of 91.
The number 5 becomes the next digit in our result. 
Result so far: 3355.0
If we subtract 1050 from 1141, we get 91.
Append the next digit (6) from the dividend to 91 and continue with: 916 / 210

On to step 7:
916 divided by 210 is 4 with a remainder of 76.
Write down 4 as next digit of the result. 
Result so far: 33554.0
Subtracting 840 from 916 leaves us with 76.
Grab the next digit (1) from the dividend, add it to 76, then carry on: 761 / 210

Step 8:
When dividing 761 by 210, we get 3 with a remainder of 131.
Write down 3 as next digit of the result. 
Result so far: 335543.0
Deduct 630 from 761 and we're left with 131.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1310, and continue the process.

Going ahead to step 9:
210 goes into 1310 6 times with a remainder of 50.
Use 6 as the next digit of our solution. 
Result so far: 335543.6
If we subtract 1260 from 1310, 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.

Step 10:
When dividing 500 by 210, we get 2 with a remainder of 80.
Write down 2 as next digit of the result. 
Result so far: 335543.62
Subtract 420 from 500 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Let's proceed to step 11:
210 can be fit into 800 3 times, resulting in a remainder of 170.
Record the quotient 3 as the next digit in the result. 
Result so far: 335543.623
Deduct 630 from 800 and we're left with 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Step 12:
1700 divided by 210 is 8 with a remainder of 20.
Record the quotient 8 as the next digit in the result. 
Result so far: 335543.6238
If we take 1680 away from 1700, 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.

On to step 13:
The number 210 fits into 200 0 times, leaving a remainder of 200.
Record the quotient 0 as the next digit in the result. 
Result so far: 335543.6238
Subtracting 0 from 200 leaves us with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Moving on to step 14:
The number 210 fits into 2000 9 times, leaving a remainder of 110.
Put 9 as the next digit of the answer. 
Result so far: 335543.623809
The remainder is 110 after subtracting 1890 from 2000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Step 15:
210 goes into 1100 5 times with a remainder of 50.
Use 5 as the next digit of our solution. 
Result so far: 335543.6238095
Subtract 1050 from 1100 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.

On to step 16:
210 goes into 500 2 times with a remainder of 80.
Write down 2 as next digit of the result. 
Result so far: 335543.62380952
Subtracting 420 from 500 leaves us with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

In conclusion, the division gives 335543.62380952 with a balance of 8e-08.
