60698420 ÷ 388 
The aim is to understand the frequency of 388 in 60698420.

Let's proceed to step 1:
The number 388 fits into 6 0 times, leaving a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Take the next digit (0) from the dividend and append it to 6, then repeat: 60 / 388

Moving on to step 2:
388 can be fit into 60 0 times, resulting in a remainder of 60.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 60 to get 60.
Take the next digit (6) from the dividend and append it to 60, then repeat: 606 / 388

Step 3:
388 goes into 606 1 times with a remainder of 218.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 388 from 606 to get 218.
Include the next digit (9) from the dividend after 218, then repeat: 2189 / 388

Step 4:
The number 388 fits into 2189 5 times, leaving a remainder of 249.
The next digit of our result is 5. 
Result so far: 15.0
If we take 1940 away from 2189, we end up with 249.
Fetch the next digit (8) from the dividend, attach it to 249 and continue: 2498 / 388

Advancing to step 5:
If we divide 2498 by 388, we get 6 and a remainder of 170.
The number 6 becomes the next digit in our result. 
Result so far: 156.0
The remainder is 170 after subtracting 2328 from 2498.
Include the next digit (4) from the dividend after 170, then repeat: 1704 / 388

Advancing to step 6:
388 can be fit into 1704 4 times, resulting in a remainder of 152.
Put 4 as the next digit of the answer. 
Result so far: 1564.0
Subtracting 1552 from 1704 leaves us with 152.
Include the next digit (2) from the dividend after 152, then repeat: 1522 / 388

Going ahead to step 7:
When dividing 1522 by 388, we get 3 with a remainder of 358.
Use 3 as the next digit of our solution. 
Result so far: 15643.0
If we subtract 1164 from 1522, we get 358.
Grab the next digit (0) from the dividend, add it to 358, then carry on: 3580 / 388

On to step 8:
3580 divided by 388 is 9 with a remainder of 88.
Write down 9 as next digit of the result. 
Result so far: 156439.0
If we take 3492 away from 3580, we end up with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Advancing to step 9:
The number 388 fits into 880 2 times, leaving a remainder of 104.
Record the quotient 2 as the next digit in the result. 
Result so far: 156439.2
If we take 776 away from 880, we end up with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Step 10:
1040 divided by 388 is 2 with a remainder of 264.
Record the quotient 2 as the next digit in the result. 
Result so far: 156439.22
If we take 776 away from 1040, we end up with 264.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

After the division, we end up with 156439.22 and a remainder of 0.264.
