We look at the division of 43086017 by 219 
The aim is to understand the frequency of 219 in 43086017.

Going ahead to step 1:
The number 219 fits into 4 0 times, leaving a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Bring next digit (3) of the dividend behind the 4 and repeat the process: 43 / 219

On to step 2:
When dividing 43 by 219, we get 0 with a remainder of 43.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 43, we end up with 43.
Take the next digit (0) from the dividend and append it to 43, then repeat: 430 / 219

Moving on to step 3:
219 can be fit into 430 1 times, resulting in a remainder of 211.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 219 from 430 to get 211.
Fetch the next digit (8) from the dividend, attach it to 211 and continue: 2118 / 219

Moving on to step 4:
2118 divided by 219 is 9 with a remainder of 147.
Write down 9 as next digit of the result. 
Result so far: 19.0
If we take 1971 away from 2118, we end up with 147.
Bring next digit (6) of the dividend behind the 147 and repeat the process: 1476 / 219

Advancing to step 5:
The number 219 fits into 1476 6 times, leaving a remainder of 162.
Put 6 as the next digit of the answer. 
Result so far: 196.0
Subtracting 1314 from 1476 leaves us with 162.
Take the next digit (0) from the dividend and append it to 162, then repeat: 1620 / 219

Advancing to step 6:
If we divide 1620 by 219, we get 7 and a remainder of 87.
Put 7 as the next digit of the answer. 
Result so far: 1967.0
If we subtract 1533 from 1620, we get 87.
Grab the next digit (1) from the dividend, add it to 87, then carry on: 871 / 219

On to step 7:
When dividing 871 by 219, we get 3 with a remainder of 214.
Record the quotient 3 as the next digit in the result. 
Result so far: 19673.0
Subtracting 657 from 871 leaves us with 214.
Include the next digit (7) from the dividend after 214, then repeat: 2147 / 219

Going ahead to step 8:
219 goes into 2147 9 times with a remainder of 176.
The number 9 becomes the next digit in our result. 
Result so far: 196739.0
If we subtract 1971 from 2147, we get 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Moving on to step 9:
The number 219 fits into 1760 8 times, leaving a remainder of 8.
The number 8 becomes the next digit in our result. 
Result so far: 196739.8
If we subtract 1752 from 1760, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 10:
219 can be fit into 80 0 times, resulting in a remainder of 80.
Put 0 as the next digit of the answer. 
Result so far: 196739.8
Deduct 0 from 80 and we're left 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.

Let's proceed to step 11:
219 can be fit into 800 3 times, resulting in a remainder of 143.
Record the quotient 3 as the next digit in the result. 
Result so far: 196739.803
If we take 657 away from 800, we end up with 143.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1430, and continue the process.

On to step 12:
219 can be fit into 1430 6 times, resulting in a remainder of 116.
Record the quotient 6 as the next digit in the result. 
Result so far: 196739.8036
If we subtract 1314 from 1430, we get 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Let's proceed to step 13:
When dividing 1160 by 219, we get 5 with a remainder of 65.
The number 5 becomes the next digit in our result. 
Result so far: 196739.80365
Subtract 1095 from 1160 to get 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Step 14:
If we divide 650 by 219, we get 2 and a remainder of 212.
Use 2 as the next digit of our solution. 
Result so far: 196739.803652
Subtracting 438 from 650 leaves us with 212.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

Moving on to step 15:
If we divide 2120 by 219, we get 9 and a remainder of 149.
The number 9 becomes the next digit in our result. 
Result so far: 196739.8036529
If we subtract 1971 from 2120, we get 149.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1490, and continue the process.

Advancing to step 16:
219 goes into 1490 6 times with a remainder of 176.
Put 6 as the next digit of the answer. 
Result so far: 196739.80365296
Subtract 1314 from 1490 to get 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

The final outcome is 196739.80365296, with a leftover of 1.76e-07.
