99981656 divided by 42 
The aim is to understand the frequency of 42 in 99981656.

On to step 1:
42 goes into 9 0 times with a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Fetch the next digit (9) from the dividend, attach it to 9 and continue: 99 / 42

Advancing to step 2:
42 can be fit into 99 2 times, resulting in a remainder of 15.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtract 84 from 99 to get 15.
Bring next digit (9) of the dividend behind the 15 and repeat the process: 159 / 42

Let's proceed to step 3:
159 divided by 42 is 3 with a remainder of 33.
Use 3 as the next digit of our solution. 
Result so far: 23.0
Subtracting 126 from 159 leaves us with 33.
Append the next digit (8) from the dividend to 33 and continue with: 338 / 42

Moving on to step 4:
The number 42 fits into 338 8 times, leaving a remainder of 2.
Put 8 as the next digit of the answer. 
Result so far: 238.0
Subtract 336 from 338 to get 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 42

Step 5:
If we divide 21 by 42, we get 0 and a remainder of 21.
Use 0 as the next digit of our solution. 
Result so far: 2380.0
If we take 0 away from 21, we end up with 21.
Include the next digit (6) from the dividend after 21, then repeat: 216 / 42

Step 6:
If we divide 216 by 42, we get 5 and a remainder of 6.
Write down 5 as next digit of the result. 
Result so far: 23805.0
If we subtract 210 from 216, we get 6.
Append the next digit (5) from the dividend to 6 and continue with: 65 / 42

Advancing to step 7:
42 goes into 65 1 times with a remainder of 23.
Put 1 as the next digit of the answer. 
Result so far: 238051.0
If we take 42 away from 65, we end up with 23.
Bring next digit (6) of the dividend behind the 23 and repeat the process: 236 / 42

Going ahead to step 8:
If we divide 236 by 42, we get 5 and a remainder of 26.
Use 5 as the next digit of our solution. 
Result so far: 2380515.0
If we subtract 210 from 236, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Let's proceed to step 9:
If we divide 260 by 42, we get 6 and a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 2380515.6
Subtracting 252 from 260 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 10:
The number 42 fits into 80 1 times, leaving a remainder of 38.
The next digit of our result is 1. 
Result so far: 2380515.61
If we take 42 away from 80, 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.

Step 11:
The number 42 fits into 380 9 times, leaving a remainder of 2.
Record the quotient 9 as the next digit in the result. 
Result so far: 2380515.619
If we take 378 away from 380, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 12:
The number 42 fits into 20 0 times, leaving a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 2380515.619
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 13:
42 goes into 200 4 times with a remainder of 32.
The next digit of our result is 4. 
Result so far: 2380515.61904
The remainder is 32 after subtracting 168 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 14:
When dividing 320 by 42, we get 7 with a remainder of 26.
Use 7 as the next digit of our solution. 
Result so far: 2380515.619047
Deduct 294 from 320 and we're left with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Moving on to step 15:
42 goes into 260 6 times with a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 2380515.6190476
Subtract 252 from 260 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 16:
If we divide 80 by 42, we get 1 and a remainder of 38.
Use 1 as the next digit of our solution. 
Result so far: 2380515.61904761
Subtract 42 from 80 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Our division results in 2380515.61904761 with a remaining 3.8e-08.
