74214117 divided by 602 
The aim is to understand the frequency of 602 in 74214117.

On to step 1:
602 goes into 7 0 times with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Append the next digit (4) from the dividend to 7 and continue with: 74 / 602

On to step 2:
When dividing 74 by 602, we get 0 with a remainder of 74.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 74, we end up with 74.
Bring next digit (2) of the dividend behind the 74 and repeat the process: 742 / 602

Advancing to step 3:
742 divided by 602 is 1 with a remainder of 140.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 602 from 742 leaves us with 140.
Bring next digit (1) of the dividend behind the 140 and repeat the process: 1401 / 602

Let's proceed to step 4:
The number 602 fits into 1401 2 times, leaving a remainder of 197.
Put 2 as the next digit of the answer. 
Result so far: 12.0
Subtract 1204 from 1401 to get 197.
Include the next digit (4) from the dividend after 197, then repeat: 1974 / 602

Step 5:
602 can be fit into 1974 3 times, resulting in a remainder of 168.
The next digit of our result is 3. 
Result so far: 123.0
Subtracting 1806 from 1974 leaves us with 168.
Take the next digit (1) from the dividend and append it to 168, then repeat: 1681 / 602

Going ahead to step 6:
1681 divided by 602 is 2 with a remainder of 477.
Record the quotient 2 as the next digit in the result. 
Result so far: 1232.0
If we subtract 1204 from 1681, we get 477.
Append the next digit (1) from the dividend to 477 and continue with: 4771 / 602

Moving on to step 7:
If we divide 4771 by 602, we get 7 and a remainder of 557.
The number 7 becomes the next digit in our result. 
Result so far: 12327.0
The remainder is 557 after subtracting 4214 from 4771.
Grab the next digit (7) from the dividend, add it to 557, then carry on: 5577 / 602

Step 8:
The number 602 fits into 5577 9 times, leaving a remainder of 159.
Put 9 as the next digit of the answer. 
Result so far: 123279.0
The remainder is 159 after subtracting 5418 from 5577.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1590, and continue the process.

Moving on to step 9:
1590 divided by 602 is 2 with a remainder of 386.
Put 2 as the next digit of the answer. 
Result so far: 123279.2
The remainder is 386 after subtracting 1204 from 1590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3860, and continue the process.

Advancing to step 10:
When dividing 3860 by 602, we get 6 with a remainder of 248.
Put 6 as the next digit of the answer. 
Result so far: 123279.26
The remainder is 248 after subtracting 3612 from 3860.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

Advancing to step 11:
602 can be fit into 2480 4 times, resulting in a remainder of 72.
Put 4 as the next digit of the answer. 
Result so far: 123279.264
If we take 2408 away from 2480, we end up with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Step 12:
If we divide 720 by 602, we get 1 and a remainder of 118.
Write down 1 as next digit of the result. 
Result so far: 123279.2641
Subtract 602 from 720 to get 118.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

On to step 13:
The number 602 fits into 1180 1 times, leaving a remainder of 578.
Use 1 as the next digit of our solution. 
Result so far: 123279.26411
Deduct 602 from 1180 and we're left with 578.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5780, and continue the process.

The final outcome is 123279.26411, with a leftover of 0.000578.
