We look at the division of 87085437 by 819 
The aim is to understand the frequency of 819 in 87085437.

Going ahead to step 1:
If we divide 8 by 819, we get 0 and a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Take the next digit (7) from the dividend and append it to 8, then repeat: 87 / 819

Let's proceed to step 2:
When dividing 87 by 819, we get 0 with a remainder of 87.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 87, we get 87.
Include the next digit (0) from the dividend after 87, then repeat: 870 / 819

Moving on to step 3:
When dividing 870 by 819, we get 1 with a remainder of 51.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 819 away from 870, we end up with 51.
Fetch the next digit (8) from the dividend, attach it to 51 and continue: 518 / 819

Going ahead to step 4:
819 can be fit into 518 0 times, resulting in a remainder of 518.
The next digit of our result is 0. 
Result so far: 10.0
The remainder is 518 after subtracting 0 from 518.
Grab the next digit (5) from the dividend, add it to 518, then carry on: 5185 / 819

Going ahead to step 5:
The number 819 fits into 5185 6 times, leaving a remainder of 271.
Record the quotient 6 as the next digit in the result. 
Result so far: 106.0
The remainder is 271 after subtracting 4914 from 5185.
Include the next digit (4) from the dividend after 271, then repeat: 2714 / 819

Advancing to step 6:
If we divide 2714 by 819, we get 3 and a remainder of 257.
Record the quotient 3 as the next digit in the result. 
Result so far: 1063.0
Subtracting 2457 from 2714 leaves us with 257.
Append the next digit (3) from the dividend to 257 and continue with: 2573 / 819

Advancing to step 7:
When dividing 2573 by 819, we get 3 with a remainder of 116.
Write down 3 as next digit of the result. 
Result so far: 10633.0
If we take 2457 away from 2573, we end up with 116.
Grab the next digit (7) from the dividend, add it to 116, then carry on: 1167 / 819

Step 8:
819 can be fit into 1167 1 times, resulting in a remainder of 348.
The next digit of our result is 1. 
Result so far: 106331.0
If we take 819 away from 1167, we end up with 348.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3480, and continue the process.

Let's proceed to step 9:
When dividing 3480 by 819, we get 4 with a remainder of 204.
The next digit of our result is 4. 
Result so far: 106331.4
Subtract 3276 from 3480 to get 204.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

Step 10:
819 goes into 2040 2 times with a remainder of 402.
Record the quotient 2 as the next digit in the result. 
Result so far: 106331.42
Subtract 1638 from 2040 to get 402.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4020, and continue the process.

On to step 11:
The number 819 fits into 4020 4 times, leaving a remainder of 744.
Put 4 as the next digit of the answer. 
Result so far: 106331.424
If we take 3276 away from 4020, we end up with 744.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7440, and continue the process.

Moving on to step 12:
7440 divided by 819 is 9 with a remainder of 69.
Put 9 as the next digit of the answer. 
Result so far: 106331.4249
Subtract 7371 from 7440 to get 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

On to step 13:
If we divide 690 by 819, we get 0 and a remainder of 690.
Put 0 as the next digit of the answer. 
Result so far: 106331.4249
If we take 0 away from 690, we end up with 690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6900, and continue the process.

Let's proceed to step 14:
When dividing 6900 by 819, we get 8 with a remainder of 348.
Put 8 as the next digit of the answer. 
Result so far: 106331.424908
The remainder is 348 after subtracting 6552 from 6900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3480, and continue the process.

Let's proceed to step 15:
The number 819 fits into 3480 4 times, leaving a remainder of 204.
Write down 4 as next digit of the result. 
Result so far: 106331.4249084
Subtract 3276 from 3480 to get 204.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

On to step 16:
819 can be fit into 2040 2 times, resulting in a remainder of 402.
Record the quotient 2 as the next digit in the result. 
Result so far: 106331.42490842
The remainder is 402 after subtracting 1638 from 2040.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4020, and continue the process.

In conclusion, the division gives 106331.42490842 with a balance of 4.02e-07.
