739889 ÷ 42 
The aim is to understand the frequency of 42 in 739889.

Going ahead to step 1:
The number 42 fits into 7 0 times, leaving a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Append the next digit (3) from the dividend to 7 and continue with: 73 / 42

Let's proceed to step 2:
73 divided by 42 is 1 with a remainder of 31.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 42 from 73, we get 31.
Fetch the next digit (9) from the dividend, attach it to 31 and continue: 319 / 42

Advancing to step 3:
If we divide 319 by 42, we get 7 and a remainder of 25.
Use 7 as the next digit of our solution. 
Result so far: 17.0
Subtracting 294 from 319 leaves us with 25.
Bring next digit (8) of the dividend behind the 25 and repeat the process: 258 / 42

Let's proceed to step 4:
258 divided by 42 is 6 with a remainder of 6.
Put 6 as the next digit of the answer. 
Result so far: 176.0
Subtract 252 from 258 to get 6.
Grab the next digit (8) from the dividend, add it to 6, then carry on: 68 / 42

Let's proceed to step 5:
42 goes into 68 1 times with a remainder of 26.
The next digit of our result is 1. 
Result so far: 1761.0
If we subtract 42 from 68, we get 26.
Fetch the next digit (9) from the dividend, attach it to 26 and continue: 269 / 42

Moving on to step 6:
When dividing 269 by 42, we get 6 with a remainder of 17.
Record the quotient 6 as the next digit in the result. 
Result so far: 17616.0
If we subtract 252 from 269, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

On to step 7:
The number 42 fits into 170 4 times, leaving a remainder of 2.
Write down 4 as next digit of the result. 
Result so far: 17616.4
If we take 168 away from 170, 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.

Going ahead to step 8:
If we divide 20 by 42, we get 0 and a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 17616.4
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.

Step 9:
If we divide 200 by 42, we get 4 and a remainder of 32.
Record the quotient 4 as the next digit in the result. 
Result so far: 17616.404
Deduct 168 from 200 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 10:
When dividing 320 by 42, we get 7 with a remainder of 26.
Record the quotient 7 as the next digit in the result. 
Result so far: 17616.4047
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.

Let's proceed to step 11:
When dividing 260 by 42, we get 6 with a remainder of 8.
The next digit of our result is 6. 
Result so far: 17616.40476
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.

On to step 12:
When dividing 80 by 42, we get 1 with a remainder of 38.
Write down 1 as next digit of the result. 
Result so far: 17616.404761
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.

Moving on to step 13:
42 can be fit into 380 9 times, resulting in a remainder of 2.
The next digit of our result is 9. 
Result so far: 17616.4047619
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.

Step 14:
42 can be fit into 20 0 times, resulting in a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 17616.4047619
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

After the division, we end up with 17616.4047619 and a remainder of 2e-08.
