We look at the division of 76214621 by 714 
The aim is to understand the frequency of 714 in 76214621.

Let's proceed to step 1:
If we divide 7 by 714, we get 0 and a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Fetch the next digit (6) from the dividend, attach it to 7 and continue: 76 / 714

Step 2:
714 can be fit into 76 0 times, resulting in a remainder of 76.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 76 to get 76.
Append the next digit (2) from the dividend to 76 and continue with: 762 / 714

Going ahead to step 3:
762 divided by 714 is 1 with a remainder of 48.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 714 away from 762, we end up with 48.
Bring next digit (1) of the dividend behind the 48 and repeat the process: 481 / 714

Step 4:
481 divided by 714 is 0 with a remainder of 481.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
Subtracting 0 from 481 leaves us with 481.
Fetch the next digit (4) from the dividend, attach it to 481 and continue: 4814 / 714

Going ahead to step 5:
714 can be fit into 4814 6 times, resulting in a remainder of 530.
Record the quotient 6 as the next digit in the result. 
Result so far: 106.0
If we take 4284 away from 4814, we end up with 530.
Take the next digit (6) from the dividend and append it to 530, then repeat: 5306 / 714

Advancing to step 6:
The number 714 fits into 5306 7 times, leaving a remainder of 308.
Use 7 as the next digit of our solution. 
Result so far: 1067.0
Deduct 4998 from 5306 and we're left with 308.
Grab the next digit (2) from the dividend, add it to 308, then carry on: 3082 / 714

Going ahead to step 7:
When dividing 3082 by 714, we get 4 with a remainder of 226.
Use 4 as the next digit of our solution. 
Result so far: 10674.0
Subtracting 2856 from 3082 leaves us with 226.
Bring next digit (1) of the dividend behind the 226 and repeat the process: 2261 / 714

On to step 8:
The number 714 fits into 2261 3 times, leaving a remainder of 119.
The number 3 becomes the next digit in our result. 
Result so far: 106743.0
Deduct 2142 from 2261 and we're left with 119.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1190, and continue the process.

Moving on to step 9:
1190 divided by 714 is 1 with a remainder of 476.
The next digit of our result is 1. 
Result so far: 106743.1
Subtract 714 from 1190 to get 476.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4760, and continue the process.

Going ahead to step 10:
The number 714 fits into 4760 6 times, leaving a remainder of 476.
Record the quotient 6 as the next digit in the result. 
Result so far: 106743.16
Subtracting 4284 from 4760 leaves us with 476.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4760, and continue the process.

On to step 11:
If we divide 4760 by 714, we get 6 and a remainder of 476.
The next digit of our result is 6. 
Result so far: 106743.166
Subtracting 4284 from 4760 leaves us with 476.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4760, and continue the process.

The final outcome is 106743.166, with a leftover of 0.0476.
