We divide 8499991 by 414
The aim is to understand the frequency of 414 in 8499991.

On to step 1:
If we divide 8 by 414, we get 0 and a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Grab the next digit (4) from the dividend, add it to 8, then carry on: 84 / 414

Step 2:
414 goes into 84 0 times with a remainder of 84.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 84, we end up with 84.
Fetch the next digit (9) from the dividend, attach it to 84 and continue: 849 / 414

On to step 3:
414 can be fit into 849 2 times, resulting in a remainder of 21.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtract 828 from 849 to get 21.
Fetch the next digit (9) from the dividend, attach it to 21 and continue: 219 / 414

Advancing to step 4:
219 divided by 414 is 0 with a remainder of 219.
The next digit of our result is 0. 
Result so far: 20.0
Deduct 0 from 219 and we're left with 219.
Append the next digit (9) from the dividend to 219 and continue with: 2199 / 414

Let's proceed to step 5:
The number 414 fits into 2199 5 times, leaving a remainder of 129.
The number 5 becomes the next digit in our result. 
Result so far: 205.0
Subtracting 2070 from 2199 leaves us with 129.
Append the next digit (9) from the dividend to 129 and continue with: 1299 / 414

Going ahead to step 6:
414 can be fit into 1299 3 times, resulting in a remainder of 57.
The number 3 becomes the next digit in our result. 
Result so far: 2053.0
If we subtract 1242 from 1299, we get 57.
Fetch the next digit (1) from the dividend, attach it to 57 and continue: 571 / 414

Let's proceed to step 7:
The number 414 fits into 571 1 times, leaving a remainder of 157.
Use 1 as the next digit of our solution. 
Result so far: 20531.0
The remainder is 157 after subtracting 414 from 571.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1570, and continue the process.

Moving on to step 8:
The number 414 fits into 1570 3 times, leaving a remainder of 328.
Write down 3 as next digit of the result. 
Result so far: 20531.3
If we subtract 1242 from 1570, we get 328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

On to step 9:
When dividing 3280 by 414, we get 7 with a remainder of 382.
The number 7 becomes the next digit in our result. 
Result so far: 20531.37
If we subtract 2898 from 3280, we get 382.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3820, and continue the process.

Moving on to step 10:
3820 divided by 414 is 9 with a remainder of 94.
Write down 9 as next digit of the result. 
Result so far: 20531.379
Subtracting 3726 from 3820 leaves us with 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Step 11:
The number 414 fits into 940 2 times, leaving a remainder of 112.
Use 2 as the next digit of our solution. 
Result so far: 20531.3792
If we take 828 away from 940, we end up with 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Step 12:
414 can be fit into 1120 2 times, resulting in a remainder of 292.
The next digit of our result is 2. 
Result so far: 20531.37922
Subtracting 828 from 1120 leaves us with 292.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2920, and continue the process.

The final result is 20531.37922 with a remainder of 0.000292.
