66562121 ÷ 614 
The aim is to understand the frequency of 614 in 66562121.

Step 1:
If we divide 6 by 614, we get 0 and a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 614

On to step 2:
66 divided by 614 is 0 with a remainder of 66.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 66 to get 66.
Take the next digit (5) from the dividend and append it to 66, then repeat: 665 / 614

Step 3:
The number 614 fits into 665 1 times, leaving a remainder of 51.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 614 from 665 to get 51.
Include the next digit (6) from the dividend after 51, then repeat: 516 / 614

Going ahead to step 4:
614 can be fit into 516 0 times, resulting in a remainder of 516.
Put 0 as the next digit of the answer. 
Result so far: 10.0
Subtract 0 from 516 to get 516.
Include the next digit (2) from the dividend after 516, then repeat: 5162 / 614

Let's proceed to step 5:
If we divide 5162 by 614, we get 8 and a remainder of 250.
The next digit of our result is 8. 
Result so far: 108.0
Deduct 4912 from 5162 and we're left with 250.
Fetch the next digit (1) from the dividend, attach it to 250 and continue: 2501 / 614

Let's proceed to step 6:
The number 614 fits into 2501 4 times, leaving a remainder of 45.
Write down 4 as next digit of the result. 
Result so far: 1084.0
Deduct 2456 from 2501 and we're left with 45.
Bring next digit (2) of the dividend behind the 45 and repeat the process: 452 / 614

Advancing to step 7:
If we divide 452 by 614, we get 0 and a remainder of 452.
Put 0 as the next digit of the answer. 
Result so far: 10840.0
Subtract 0 from 452 to get 452.
Append the next digit (1) from the dividend to 452 and continue with: 4521 / 614

Let's proceed to step 8:
614 can be fit into 4521 7 times, resulting in a remainder of 223.
Record the quotient 7 as the next digit in the result. 
Result so far: 108407.0
The remainder is 223 after subtracting 4298 from 4521.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2230, and continue the process.

Let's proceed to step 9:
When dividing 2230 by 614, we get 3 with a remainder of 388.
Record the quotient 3 as the next digit in the result. 
Result so far: 108407.3
Subtract 1842 from 2230 to get 388.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3880, and continue the process.

Going ahead to step 10:
When dividing 3880 by 614, we get 6 with a remainder of 196.
The number 6 becomes the next digit in our result. 
Result so far: 108407.36
Deduct 3684 from 3880 and we're left with 196.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

Let's proceed to step 11:
614 goes into 1960 3 times with a remainder of 118.
Put 3 as the next digit of the answer. 
Result so far: 108407.363
The remainder is 118 after subtracting 1842 from 1960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

Going ahead to step 12:
614 goes into 1180 1 times with a remainder of 566.
The next digit of our result is 1. 
Result so far: 108407.3631
Subtract 614 from 1180 to get 566.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5660, and continue the process.

On to step 13:
614 can be fit into 5660 9 times, resulting in a remainder of 134.
Record the quotient 9 as the next digit in the result. 
Result so far: 108407.36319
The remainder is 134 after subtracting 5526 from 5660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

Moving on to step 14:
When dividing 1340 by 614, we get 2 with a remainder of 112.
Use 2 as the next digit of our solution. 
Result so far: 108407.363192
If we subtract 1228 from 1340, we get 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Advancing to step 15:
When dividing 1120 by 614, we get 1 with a remainder of 506.
Use 1 as the next digit of our solution. 
Result so far: 108407.3631921
The remainder is 506 after subtracting 614 from 1120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5060, and continue the process.

Advancing to step 16:
614 can be fit into 5060 8 times, resulting in a remainder of 148.
The next digit of our result is 8. 
Result so far: 108407.36319218
If we take 4912 away from 5060, we end up with 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

The final outcome is 108407.36319218, with a leftover of 1.48e-07.
