43694169 ÷ 407 
The aim is to understand the frequency of 407 in 43694169.

Moving on to step 1:
When dividing 4 by 407, we get 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Take the next digit (3) from the dividend and append it to 4, then repeat: 43 / 407

Let's proceed to step 2:
407 goes into 43 0 times with a remainder of 43.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 43 after subtracting 0 from 43.
Grab the next digit (6) from the dividend, add it to 43, then carry on: 436 / 407

Let's proceed to step 3:
436 divided by 407 is 1 with a remainder of 29.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 29 after subtracting 407 from 436.
Grab the next digit (9) from the dividend, add it to 29, then carry on: 299 / 407

Let's proceed to step 4:
407 goes into 299 0 times with a remainder of 299.
Use 0 as the next digit of our solution. 
Result so far: 10.0
If we take 0 away from 299, we end up with 299.
Append the next digit (4) from the dividend to 299 and continue with: 2994 / 407

Going ahead to step 5:
407 can be fit into 2994 7 times, resulting in a remainder of 145.
The number 7 becomes the next digit in our result. 
Result so far: 107.0
Subtract 2849 from 2994 to get 145.
Append the next digit (1) from the dividend to 145 and continue with: 1451 / 407

Let's proceed to step 6:
The number 407 fits into 1451 3 times, leaving a remainder of 230.
Use 3 as the next digit of our solution. 
Result so far: 1073.0
If we subtract 1221 from 1451, we get 230.
Include the next digit (6) from the dividend after 230, then repeat: 2306 / 407

Step 7:
When dividing 2306 by 407, we get 5 with a remainder of 271.
The number 5 becomes the next digit in our result. 
Result so far: 10735.0
Subtracting 2035 from 2306 leaves us with 271.
Append the next digit (9) from the dividend to 271 and continue with: 2719 / 407

Going ahead to step 8:
The number 407 fits into 2719 6 times, leaving a remainder of 277.
Use 6 as the next digit of our solution. 
Result so far: 107356.0
If we subtract 2442 from 2719, we get 277.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2770, and continue the process.

On to step 9:
407 can be fit into 2770 6 times, resulting in a remainder of 328.
The next digit of our result is 6. 
Result so far: 107356.6
If we subtract 2442 from 2770, we get 328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

Going ahead to step 10:
If we divide 3280 by 407, we get 8 and a remainder of 24.
Put 8 as the next digit of the answer. 
Result so far: 107356.68
Subtracting 3256 from 3280 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 11:
When dividing 240 by 407, we get 0 with a remainder of 240.
The number 0 becomes the next digit in our result. 
Result so far: 107356.68
The remainder is 240 after subtracting 0 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Going ahead to step 12:
The number 407 fits into 2400 5 times, leaving a remainder of 365.
Use 5 as the next digit of our solution. 
Result so far: 107356.6805
Subtracting 2035 from 2400 leaves us with 365.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3650, and continue the process.

Let's proceed to step 13:
If we divide 3650 by 407, we get 8 and a remainder of 394.
Record the quotient 8 as the next digit in the result. 
Result so far: 107356.68058
Subtracting 3256 from 3650 leaves us with 394.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3940, and continue the process.

Step 14:
3940 divided by 407 is 9 with a remainder of 277.
Put 9 as the next digit of the answer. 
Result so far: 107356.680589
Subtract 3663 from 3940 to get 277.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2770, and continue the process.

Step 15:
407 can be fit into 2770 6 times, resulting in a remainder of 328.
Write down 6 as next digit of the result. 
Result so far: 107356.6805896
Subtract 2442 from 2770 to get 328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

Step 16:
When dividing 3280 by 407, we get 8 with a remainder of 24.
Write down 8 as next digit of the result. 
Result so far: 107356.68058968
The remainder is 24 after subtracting 3256 from 3280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

The quotient of the division is 107356.68058968, and the remainder is 2.4e-08.
