72101662 ÷ 602 
The aim is to understand the frequency of 602 in 72101662.

Let's proceed to step 1:
The number 602 fits into 7 0 times, leaving a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Bring next digit (2) of the dividend behind the 7 and repeat the process: 72 / 602

Step 2:
If we divide 72 by 602, we get 0 and a remainder of 72.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 72 and we're left with 72.
Include the next digit (1) from the dividend after 72, then repeat: 721 / 602

Going ahead to step 3:
If we divide 721 by 602, we get 1 and a remainder of 119.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 602 from 721 to get 119.
Fetch the next digit (0) from the dividend, attach it to 119 and continue: 1190 / 602

On to step 4:
602 goes into 1190 1 times with a remainder of 588.
The next digit of our result is 1. 
Result so far: 11.0
Subtract 602 from 1190 to get 588.
Include the next digit (1) from the dividend after 588, then repeat: 5881 / 602

Let's proceed to step 5:
The number 602 fits into 5881 9 times, leaving a remainder of 463.
The number 9 becomes the next digit in our result. 
Result so far: 119.0
Subtract 5418 from 5881 to get 463.
Fetch the next digit (6) from the dividend, attach it to 463 and continue: 4636 / 602

Advancing to step 6:
The number 602 fits into 4636 7 times, leaving a remainder of 422.
Put 7 as the next digit of the answer. 
Result so far: 1197.0
The remainder is 422 after subtracting 4214 from 4636.
Bring next digit (6) of the dividend behind the 422 and repeat the process: 4226 / 602

Going ahead to step 7:
If we divide 4226 by 602, we get 7 and a remainder of 12.
Record the quotient 7 as the next digit in the result. 
Result so far: 11977.0
Deduct 4214 from 4226 and we're left with 12.
Fetch the next digit (2) from the dividend, attach it to 12 and continue: 122 / 602

Going ahead to step 8:
602 goes into 122 0 times with a remainder of 122.
The number 0 becomes the next digit in our result. 
Result so far: 119770.0
Subtract 0 from 122 to get 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

Going ahead to step 9:
602 can be fit into 1220 2 times, resulting in a remainder of 16.
Use 2 as the next digit of our solution. 
Result so far: 119770.2
If we subtract 1204 from 1220, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 10:
602 can be fit into 160 0 times, resulting in a remainder of 160.
Record the quotient 0 as the next digit in the result. 
Result so far: 119770.2
Subtracting 0 from 160 leaves us with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Let's proceed to step 11:
The number 602 fits into 1600 2 times, leaving a remainder of 396.
The number 2 becomes the next digit in our result. 
Result so far: 119770.202
If we subtract 1204 from 1600, we get 396.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3960, and continue the process.

Going ahead to step 12:
602 can be fit into 3960 6 times, resulting in a remainder of 348.
Record the quotient 6 as the next digit in the result. 
Result so far: 119770.2026
If we take 3612 away from 3960, we end up with 348.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3480, and continue the process.

Going ahead to step 13:
3480 divided by 602 is 5 with a remainder of 470.
The number 5 becomes the next digit in our result. 
Result so far: 119770.20265
If we subtract 3010 from 3480, we get 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4700, and continue the process.

Let's proceed to step 14:
602 can be fit into 4700 7 times, resulting in a remainder of 486.
The next digit of our result is 7. 
Result so far: 119770.202657
Subtract 4214 from 4700 to get 486.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4860, and continue the process.

Advancing to step 15:
If we divide 4860 by 602, we get 8 and a remainder of 44.
Write down 8 as next digit of the result. 
Result so far: 119770.2026578
Deduct 4816 from 4860 and we're left with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Let's proceed to step 16:
When dividing 440 by 602, we get 0 with a remainder of 440.
The next digit of our result is 0. 
Result so far: 119770.2026578
Deduct 0 from 440 and we're left with 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

The quotient of the division is 119770.2026578, and the remainder is 4.4e-07.
