83069471 ÷ 213 
The aim is to understand the frequency of 213 in 83069471.

Moving on to step 1:
If we divide 8 by 213, we get 0 and a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Append the next digit (3) from the dividend to 8 and continue with: 83 / 213

On to step 2:
213 goes into 83 0 times with a remainder of 83.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 83, we end up with 83.
Include the next digit (0) from the dividend after 83, then repeat: 830 / 213

Step 3:
The number 213 fits into 830 3 times, leaving a remainder of 191.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Deduct 639 from 830 and we're left with 191.
Fetch the next digit (6) from the dividend, attach it to 191 and continue: 1916 / 213

On to step 4:
If we divide 1916 by 213, we get 8 and a remainder of 212.
Write down 8 as next digit of the result. 
Result so far: 38.0
The remainder is 212 after subtracting 1704 from 1916.
Grab the next digit (9) from the dividend, add it to 212, then carry on: 2129 / 213

Moving on to step 5:
When dividing 2129 by 213, we get 9 with a remainder of 212.
The next digit of our result is 9. 
Result so far: 389.0
If we take 1917 away from 2129, we end up with 212.
Grab the next digit (4) from the dividend, add it to 212, then carry on: 2124 / 213

Advancing to step 6:
213 goes into 2124 9 times with a remainder of 207.
Write down 9 as next digit of the result. 
Result so far: 3899.0
If we take 1917 away from 2124, we end up with 207.
Include the next digit (7) from the dividend after 207, then repeat: 2077 / 213

Moving on to step 7:
213 can be fit into 2077 9 times, resulting in a remainder of 160.
Use 9 as the next digit of our solution. 
Result so far: 38999.0
Subtracting 1917 from 2077 leaves us with 160.
Append the next digit (1) from the dividend to 160 and continue with: 1601 / 213

Advancing to step 8:
The number 213 fits into 1601 7 times, leaving a remainder of 110.
The number 7 becomes the next digit in our result. 
Result so far: 389997.0
If we take 1491 away from 1601, we end up with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Moving on to step 9:
If we divide 1100 by 213, we get 5 and a remainder of 35.
The number 5 becomes the next digit in our result. 
Result so far: 389997.5
The remainder is 35 after subtracting 1065 from 1100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Let's proceed to step 10:
350 divided by 213 is 1 with a remainder of 137.
Write down 1 as next digit of the result. 
Result so far: 389997.51
Deduct 213 from 350 and we're left with 137.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1370, and continue the process.

Moving on to step 11:
213 goes into 1370 6 times with a remainder of 92.
Use 6 as the next digit of our solution. 
Result so far: 389997.516
Subtracting 1278 from 1370 leaves us with 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Step 12:
The number 213 fits into 920 4 times, leaving a remainder of 68.
Use 4 as the next digit of our solution. 
Result so far: 389997.5164
If we take 852 away from 920, we end up with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

On to step 13:
213 goes into 680 3 times with a remainder of 41.
Write down 3 as next digit of the result. 
Result so far: 389997.51643
If we subtract 639 from 680, we get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Step 14:
When dividing 410 by 213, we get 1 with a remainder of 197.
The next digit of our result is 1. 
Result so far: 389997.516431
Subtracting 213 from 410 leaves us with 197.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1970, and continue the process.

Step 15:
213 goes into 1970 9 times with a remainder of 53.
The number 9 becomes the next digit in our result. 
Result so far: 389997.5164319
Deduct 1917 from 1970 and we're left with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Moving on to step 16:
If we divide 530 by 213, we get 2 and a remainder of 104.
Record the quotient 2 as the next digit in the result. 
Result so far: 389997.51643192
If we subtract 426 from 530, we get 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Our division results in 389997.51643192 with a remaining 1.04e-07.
