Let's divide 66502154 by 542
The aim is to understand the frequency of 542 in 66502154.

Going ahead to step 1:
When dividing 6 by 542, we get 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 542

Advancing to step 2:
If we divide 66 by 542, we get 0 and a remainder of 66.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 66 and we're left with 66.
Take the next digit (5) from the dividend and append it to 66, then repeat: 665 / 542

Advancing to step 3:
542 goes into 665 1 times with a remainder of 123.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 542 from 665 leaves us with 123.
Take the next digit (0) from the dividend and append it to 123, then repeat: 1230 / 542

Moving on to step 4:
1230 divided by 542 is 2 with a remainder of 146.
Put 2 as the next digit of the answer. 
Result so far: 12.0
Deduct 1084 from 1230 and we're left with 146.
Append the next digit (2) from the dividend to 146 and continue with: 1462 / 542

Going ahead to step 5:
1462 divided by 542 is 2 with a remainder of 378.
Write down 2 as next digit of the result. 
Result so far: 122.0
Subtract 1084 from 1462 to get 378.
Take the next digit (1) from the dividend and append it to 378, then repeat: 3781 / 542

Advancing to step 6:
When dividing 3781 by 542, we get 6 with a remainder of 529.
Put 6 as the next digit of the answer. 
Result so far: 1226.0
Subtracting 3252 from 3781 leaves us with 529.
Grab the next digit (5) from the dividend, add it to 529, then carry on: 5295 / 542

Advancing to step 7:
542 can be fit into 5295 9 times, resulting in a remainder of 417.
The next digit of our result is 9. 
Result so far: 12269.0
Subtracting 4878 from 5295 leaves us with 417.
Bring next digit (4) of the dividend behind the 417 and repeat the process: 4174 / 542

Advancing to step 8:
If we divide 4174 by 542, we get 7 and a remainder of 380.
Record the quotient 7 as the next digit in the result. 
Result so far: 122697.0
Deduct 3794 from 4174 and we're left with 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Moving on to step 9:
When dividing 3800 by 542, we get 7 with a remainder of 6.
Use 7 as the next digit of our solution. 
Result so far: 122697.7
The remainder is 6 after subtracting 3794 from 3800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 10:
542 goes into 60 0 times with a remainder of 60.
Use 0 as the next digit of our solution. 
Result so far: 122697.7
The remainder is 60 after subtracting 0 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 11:
542 can be fit into 600 1 times, resulting in a remainder of 58.
Put 1 as the next digit of the answer. 
Result so far: 122697.701
If we take 542 away from 600, we end up with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Moving on to step 12:
580 divided by 542 is 1 with a remainder of 38.
Record the quotient 1 as the next digit in the result. 
Result so far: 122697.7011
If we take 542 away from 580, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

The quotient of the division is 122697.7011, and the remainder is 0.00038.
