We divide 139743 by 69
The aim is to understand the frequency of 69 in 139743.

Going ahead to step 1:
69 can be fit into 1 0 times, resulting in a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Include the next digit (3) from the dividend after 1, then repeat: 13 / 69

Going ahead to step 2:
When dividing 13 by 69, we get 0 with a remainder of 13.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 13, we get 13.
Take the next digit (9) from the dividend and append it to 13, then repeat: 139 / 69

Moving on to step 3:
The number 69 fits into 139 2 times, leaving a remainder of 1.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtracting 138 from 139 leaves us with 1.
Bring next digit (7) of the dividend behind the 1 and repeat the process: 17 / 69

Step 4:
69 can be fit into 17 0 times, resulting in a remainder of 17.
Put 0 as the next digit of the answer. 
Result so far: 20.0
If we subtract 0 from 17, we get 17.
Fetch the next digit (4) from the dividend, attach it to 17 and continue: 174 / 69

Moving on to step 5:
When dividing 174 by 69, we get 2 with a remainder of 36.
Put 2 as the next digit of the answer. 
Result so far: 202.0
Subtracting 138 from 174 leaves us with 36.
Fetch the next digit (3) from the dividend, attach it to 36 and continue: 363 / 69

Step 6:
363 divided by 69 is 5 with a remainder of 18.
Record the quotient 5 as the next digit in the result. 
Result so far: 2025.0
If we subtract 345 from 363, we 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.

On to step 7:
If we divide 180 by 69, we get 2 and a remainder of 42.
The next digit of our result is 2. 
Result so far: 2025.2
If we take 138 away from 180, 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.

Step 8:
When dividing 420 by 69, we get 6 with a remainder of 6.
The next digit of our result is 6. 
Result so far: 2025.26
If we subtract 414 from 420, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 9:
69 goes into 60 0 times with a remainder of 60.
Record the quotient 0 as the next digit in the result. 
Result so far: 2025.26
Deduct 0 from 60 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 10:
69 can be fit into 600 8 times, resulting in a remainder of 48.
Use 8 as the next digit of our solution. 
Result so far: 2025.2608
If we take 552 away from 600, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 11:
69 can be fit into 480 6 times, resulting in a remainder of 66.
Put 6 as the next digit of the answer. 
Result so far: 2025.26086
Subtract 414 from 480 to get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Moving on to step 12:
660 divided by 69 is 9 with a remainder of 39.
The next digit of our result is 9. 
Result so far: 2025.260869
Subtract 621 from 660 to get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Advancing to step 13:
If we divide 390 by 69, we get 5 and a remainder of 45.
The number 5 becomes the next digit in our result. 
Result so far: 2025.2608695
If we subtract 345 from 390, we get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Going ahead to step 14:
If we divide 450 by 69, we get 6 and a remainder of 36.
Use 6 as the next digit of our solution. 
Result so far: 2025.26086956
The remainder is 36 after subtracting 414 from 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

The quotient of the division is 2025.26086956, and the remainder is 3.6e-08.
