We divide 70140110 by 819
The aim is to understand the frequency of 819 in 70140110.

On to step 1:
If we divide 7 by 819, we get 0 and a remainder of 7.
Use 0 as the next digit of our solution. 
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 / 819

Step 2:
If we divide 70 by 819, we get 0 and a remainder of 70.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 70 to get 70.
Append the next digit (1) from the dividend to 70 and continue with: 701 / 819

Step 3:
701 divided by 819 is 0 with a remainder of 701.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 701 and we're left with 701.
Take the next digit (4) from the dividend and append it to 701, then repeat: 7014 / 819

Step 4:
819 can be fit into 7014 8 times, resulting in a remainder of 462.
The next digit of our result is 8. 
Result so far: 8.0
If we take 6552 away from 7014, we end up with 462.
Grab the next digit (0) from the dividend, add it to 462, then carry on: 4620 / 819

Let's proceed to step 5:
4620 divided by 819 is 5 with a remainder of 525.
Put 5 as the next digit of the answer. 
Result so far: 85.0
Subtract 4095 from 4620 to get 525.
Include the next digit (1) from the dividend after 525, then repeat: 5251 / 819

On to step 6:
If we divide 5251 by 819, we get 6 and a remainder of 337.
The next digit of our result is 6. 
Result so far: 856.0
Deduct 4914 from 5251 and we're left with 337.
Take the next digit (1) from the dividend and append it to 337, then repeat: 3371 / 819

Step 7:
3371 divided by 819 is 4 with a remainder of 95.
Use 4 as the next digit of our solution. 
Result so far: 8564.0
If we take 3276 away from 3371, we end up with 95.
Include the next digit (0) from the dividend after 95, then repeat: 950 / 819

On to step 8:
The number 819 fits into 950 1 times, leaving a remainder of 131.
Use 1 as the next digit of our solution. 
Result so far: 85641.0
Subtract 819 from 950 to get 131.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1310, and continue the process.

Moving on to step 9:
819 can be fit into 1310 1 times, resulting in a remainder of 491.
Use 1 as the next digit of our solution. 
Result so far: 85641.1
Subtract 819 from 1310 to get 491.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4910, and continue the process.

On to step 10:
819 can be fit into 4910 5 times, resulting in a remainder of 815.
Use 5 as the next digit of our solution. 
Result so far: 85641.15
If we take 4095 away from 4910, we end up with 815.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8150, and continue the process.

On to step 11:
When dividing 8150 by 819, we get 9 with a remainder of 779.
The number 9 becomes the next digit in our result. 
Result so far: 85641.159
Subtract 7371 from 8150 to get 779.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7790, and continue the process.

Going ahead to step 12:
The number 819 fits into 7790 9 times, leaving a remainder of 419.
Use 9 as the next digit of our solution. 
Result so far: 85641.1599
Subtracting 7371 from 7790 leaves us with 419.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4190, and continue the process.

The final result is 85641.1599 with a remainder of 0.00419.
