We're dividing 1668814 by 536 
The aim is to understand the frequency of 536 in 1668814.

On to step 1:
536 goes into 1 0 times with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Grab the next digit (6) from the dividend, add it to 1, then carry on: 16 / 536

Going ahead to step 2:
536 goes into 16 0 times with a remainder of 16.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 16 and we're left with 16.
Take the next digit (6) from the dividend and append it to 16, then repeat: 166 / 536

On to step 3:
166 divided by 536 is 0 with a remainder of 166.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 166 leaves us with 166.
Bring next digit (8) of the dividend behind the 166 and repeat the process: 1668 / 536

Moving on to step 4:
When dividing 1668 by 536, we get 3 with a remainder of 60.
Write down 3 as next digit of the result. 
Result so far: 3.0
Deduct 1608 from 1668 and we're left with 60.
Take the next digit (8) from the dividend and append it to 60, then repeat: 608 / 536

Going ahead to step 5:
536 can be fit into 608 1 times, resulting in a remainder of 72.
Use 1 as the next digit of our solution. 
Result so far: 31.0
If we subtract 536 from 608, we get 72.
Append the next digit (1) from the dividend to 72 and continue with: 721 / 536

Going ahead to step 6:
When dividing 721 by 536, we get 1 with a remainder of 185.
The number 1 becomes the next digit in our result. 
Result so far: 311.0
If we subtract 536 from 721, we get 185.
Fetch the next digit (4) from the dividend, attach it to 185 and continue: 1854 / 536

Going ahead to step 7:
The number 536 fits into 1854 3 times, leaving a remainder of 246.
The next digit of our result is 3. 
Result so far: 3113.0
Deduct 1608 from 1854 and we're left with 246.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2460, and continue the process.

Advancing to step 8:
2460 divided by 536 is 4 with a remainder of 316.
Record the quotient 4 as the next digit in the result. 
Result so far: 3113.4
Deduct 2144 from 2460 and we're left with 316.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3160, and continue the process.

Let's proceed to step 9:
536 can be fit into 3160 5 times, resulting in a remainder of 480.
Put 5 as the next digit of the answer. 
Result so far: 3113.45
If we subtract 2680 from 3160, we get 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Going ahead to step 10:
When dividing 4800 by 536, we get 8 with a remainder of 512.
The number 8 becomes the next digit in our result. 
Result so far: 3113.458
Deduct 4288 from 4800 and we're left with 512.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5120, and continue the process.

Step 11:
536 can be fit into 5120 9 times, resulting in a remainder of 296.
The next digit of our result is 9. 
Result so far: 3113.4589
The remainder is 296 after subtracting 4824 from 5120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

Advancing to step 12:
536 goes into 2960 5 times with a remainder of 280.
The number 5 becomes the next digit in our result. 
Result so far: 3113.45895
Deduct 2680 from 2960 and we're left with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Step 13:
2800 divided by 536 is 5 with a remainder of 120.
The next digit of our result is 5. 
Result so far: 3113.458955
Subtracting 2680 from 2800 leaves us with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Our division results in 3113.458955 with a remaining 1.2e-05.
