39870 ÷ 67 
The aim is to understand the frequency of 67 in 39870.

On to step 1:
67 goes into 3 0 times with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 67

On to step 2:
67 goes into 39 0 times with a remainder of 39.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 39 leaves us with 39.
Bring next digit (8) of the dividend behind the 39 and repeat the process: 398 / 67

Moving on to step 3:
When dividing 398 by 67, we get 5 with a remainder of 63.
Write down 5 as next digit of the result. 
Result so far: 5.0
Subtract 335 from 398 to get 63.
Fetch the next digit (7) from the dividend, attach it to 63 and continue: 637 / 67

On to step 4:
637 divided by 67 is 9 with a remainder of 34.
Record the quotient 9 as the next digit in the result. 
Result so far: 59.0
Deduct 603 from 637 and we're left with 34.
Bring next digit (0) of the dividend behind the 34 and repeat the process: 340 / 67

On to step 5:
When dividing 340 by 67, we get 5 with a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 595.0
Subtracting 335 from 340 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 6:
67 can be fit into 50 0 times, resulting in a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 595.0
The remainder is 50 after subtracting 0 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 7:
If we divide 500 by 67, we get 7 and a remainder of 31.
The next digit of our result is 7. 
Result so far: 595.07
Deduct 469 from 500 and we're left with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

On to step 8:
310 divided by 67 is 4 with a remainder of 42.
Record the quotient 4 as the next digit in the result. 
Result so far: 595.074
If we take 268 away from 310, we end up 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.

Going ahead to step 9:
If we divide 420 by 67, we get 6 and a remainder of 18.
Use 6 as the next digit of our solution. 
Result so far: 595.0746
Subtract 402 from 420 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 10:
The number 67 fits into 180 2 times, leaving a remainder of 46.
Write down 2 as next digit of the result. 
Result so far: 595.07462
Subtract 134 from 180 to get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

On to step 11:
If we divide 460 by 67, we get 6 and a remainder of 58.
The next digit of our result is 6. 
Result so far: 595.074626
Deduct 402 from 460 and we're left 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.

Let's proceed to step 12:
67 goes into 580 8 times with a remainder of 44.
The next digit of our result is 8. 
Result so far: 595.0746268
Deduct 536 from 580 and we're left with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Let's proceed to step 13:
67 can be fit into 440 6 times, resulting in a remainder of 38.
Write down 6 as next digit of the result. 
Result so far: 595.07462686
The remainder is 38 after subtracting 402 from 440.
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 595.07462686, and the remainder is 3.8e-08.
