We look at the division of 66142050 by 942 
The aim is to understand the frequency of 942 in 66142050.

Advancing to step 1:
If we divide 6 by 942, we get 0 and a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 942

On to step 2:
If we divide 66 by 942, we get 0 and a remainder of 66.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 66 to get 66.
Take the next digit (1) from the dividend and append it to 66, then repeat: 661 / 942

Let's proceed to step 3:
942 goes into 661 0 times with a remainder of 661.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 661 leaves us with 661.
Take the next digit (4) from the dividend and append it to 661, then repeat: 6614 / 942

On to step 4:
942 goes into 6614 7 times with a remainder of 20.
Write down 7 as next digit of the result. 
Result so far: 7.0
The remainder is 20 after subtracting 6594 from 6614.
Bring next digit (2) of the dividend behind the 20 and repeat the process: 202 / 942

Advancing to step 5:
When dividing 202 by 942, we get 0 with a remainder of 202.
Write down 0 as next digit of the result. 
Result so far: 70.0
If we take 0 away from 202, we end up with 202.
Append the next digit (0) from the dividend to 202 and continue with: 2020 / 942

Step 6:
When dividing 2020 by 942, we get 2 with a remainder of 136.
The next digit of our result is 2. 
Result so far: 702.0
If we take 1884 away from 2020, we end up with 136.
Bring next digit (5) of the dividend behind the 136 and repeat the process: 1365 / 942

Going ahead to step 7:
The number 942 fits into 1365 1 times, leaving a remainder of 423.
Put 1 as the next digit of the answer. 
Result so far: 7021.0
Subtracting 942 from 1365 leaves us with 423.
Take the next digit (0) from the dividend and append it to 423, then repeat: 4230 / 942

Let's proceed to step 8:
942 can be fit into 4230 4 times, resulting in a remainder of 462.
Record the quotient 4 as the next digit in the result. 
Result so far: 70214.0
If we subtract 3768 from 4230, we get 462.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4620, and continue the process.

Going ahead to step 9:
942 can be fit into 4620 4 times, resulting in a remainder of 852.
The next digit of our result is 4. 
Result so far: 70214.4
Subtracting 3768 from 4620 leaves us with 852.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8520, and continue the process.

Advancing to step 10:
942 can be fit into 8520 9 times, resulting in a remainder of 42.
The number 9 becomes the next digit in our result. 
Result so far: 70214.49
Deduct 8478 from 8520 and we're left with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 11:
420 divided by 942 is 0 with a remainder of 420.
Use 0 as the next digit of our solution. 
Result so far: 70214.49
If we take 0 away from 420, we end up with 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

Let's proceed to step 12:
4200 divided by 942 is 4 with a remainder of 432.
Record the quotient 4 as the next digit in the result. 
Result so far: 70214.4904
Subtracting 3768 from 4200 leaves us with 432.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4320, and continue the process.

Moving on to step 13:
When dividing 4320 by 942, we get 4 with a remainder of 552.
Record the quotient 4 as the next digit in the result. 
Result so far: 70214.49044
The remainder is 552 after subtracting 3768 from 4320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5520, and continue the process.

The final outcome is 70214.49044, with a leftover of 0.000552.
