We're dividing 87403115 by 662 
The aim is to understand the frequency of 662 in 87403115.

Step 1:
If we divide 8 by 662, we get 0 and a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Take the next digit (7) from the dividend and append it to 8, then repeat: 87 / 662

On to step 2:
662 goes into 87 0 times with a remainder of 87.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 87 and we're left with 87.
Fetch the next digit (4) from the dividend, attach it to 87 and continue: 874 / 662

Going ahead to step 3:
874 divided by 662 is 1 with a remainder of 212.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 212 after subtracting 662 from 874.
Fetch the next digit (0) from the dividend, attach it to 212 and continue: 2120 / 662

Going ahead to step 4:
If we divide 2120 by 662, we get 3 and a remainder of 134.
The next digit of our result is 3. 
Result so far: 13.0
If we take 1986 away from 2120, we end up with 134.
Bring next digit (3) of the dividend behind the 134 and repeat the process: 1343 / 662

Step 5:
1343 divided by 662 is 2 with a remainder of 19.
Record the quotient 2 as the next digit in the result. 
Result so far: 132.0
The remainder is 19 after subtracting 1324 from 1343.
Take the next digit (1) from the dividend and append it to 19, then repeat: 191 / 662

Advancing to step 6:
The number 662 fits into 191 0 times, leaving a remainder of 191.
Record the quotient 0 as the next digit in the result. 
Result so far: 1320.0
If we subtract 0 from 191, we get 191.
Grab the next digit (1) from the dividend, add it to 191, then carry on: 1911 / 662

On to step 7:
662 can be fit into 1911 2 times, resulting in a remainder of 587.
The next digit of our result is 2. 
Result so far: 13202.0
Deduct 1324 from 1911 and we're left with 587.
Include the next digit (5) from the dividend after 587, then repeat: 5875 / 662

Advancing to step 8:
662 can be fit into 5875 8 times, resulting in a remainder of 579.
The number 8 becomes the next digit in our result. 
Result so far: 132028.0
Deduct 5296 from 5875 and we're left with 579.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5790, and continue the process.

On to step 9:
5790 divided by 662 is 8 with a remainder of 494.
The next digit of our result is 8. 
Result so far: 132028.8
If we subtract 5296 from 5790, we get 494.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4940, and continue the process.

Going ahead to step 10:
When dividing 4940 by 662, we get 7 with a remainder of 306.
Write down 7 as next digit of the result. 
Result so far: 132028.87
Deduct 4634 from 4940 and we're left with 306.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3060, and continue the process.

Advancing to step 11:
The number 662 fits into 3060 4 times, leaving a remainder of 412.
The next digit of our result is 4. 
Result so far: 132028.874
If we take 2648 away from 3060, we end up with 412.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4120, and continue the process.

Step 12:
When dividing 4120 by 662, we get 6 with a remainder of 148.
The next digit of our result is 6. 
Result so far: 132028.8746
If we take 3972 away from 4120, 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.

On to step 13:
662 can be fit into 1480 2 times, resulting in a remainder of 156.
Write down 2 as next digit of the result. 
Result so far: 132028.87462
Subtracting 1324 from 1480 leaves us with 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

Step 14:
662 can be fit into 1560 2 times, resulting in a remainder of 236.
Record the quotient 2 as the next digit in the result. 
Result so far: 132028.874622
If we take 1324 away from 1560, we end up with 236.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

The final outcome is 132028.874622, with a leftover of 2.36e-05.
