We divide 15787168 by 406
The aim is to understand the frequency of 406 in 15787168.

Going ahead to step 1:
When dividing 1 by 406, we get 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 406

On to step 2:
If we divide 15 by 406, we get 0 and a remainder of 15.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 15 after subtracting 0 from 15.
Take the next digit (7) from the dividend and append it to 15, then repeat: 157 / 406

Step 3:
406 goes into 157 0 times with a remainder of 157.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 157 to get 157.
Take the next digit (8) from the dividend and append it to 157, then repeat: 1578 / 406

Step 4:
If we divide 1578 by 406, we get 3 and a remainder of 360.
Write down 3 as next digit of the result. 
Result so far: 3.0
The remainder is 360 after subtracting 1218 from 1578.
Include the next digit (7) from the dividend after 360, then repeat: 3607 / 406

Going ahead to step 5:
The number 406 fits into 3607 8 times, leaving a remainder of 359.
Record the quotient 8 as the next digit in the result. 
Result so far: 38.0
Subtracting 3248 from 3607 leaves us with 359.
Include the next digit (1) from the dividend after 359, then repeat: 3591 / 406

Moving on to step 6:
If we divide 3591 by 406, we get 8 and a remainder of 343.
The next digit of our result is 8. 
Result so far: 388.0
Deduct 3248 from 3591 and we're left with 343.
Fetch the next digit (6) from the dividend, attach it to 343 and continue: 3436 / 406

Step 7:
If we divide 3436 by 406, we get 8 and a remainder of 188.
The number 8 becomes the next digit in our result. 
Result so far: 3888.0
If we subtract 3248 from 3436, we get 188.
Grab the next digit (8) from the dividend, add it to 188, then carry on: 1888 / 406

Let's proceed to step 8:
If we divide 1888 by 406, we get 4 and a remainder of 264.
The number 4 becomes the next digit in our result. 
Result so far: 38884.0
If we take 1624 away from 1888, we end up with 264.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

Let's proceed to step 9:
2640 divided by 406 is 6 with a remainder of 204.
The number 6 becomes the next digit in our result. 
Result so far: 38884.6
The remainder is 204 after subtracting 2436 from 2640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

Advancing to step 10:
When dividing 2040 by 406, we get 5 with a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 38884.65
If we subtract 2030 from 2040, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 11:
406 goes into 100 0 times with a remainder of 100.
Put 0 as the next digit of the answer. 
Result so far: 38884.65
If we subtract 0 from 100, we get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Going ahead to step 12:
406 can be fit into 1000 2 times, resulting in a remainder of 188.
Put 2 as the next digit of the answer. 
Result so far: 38884.6502
Subtract 812 from 1000 to get 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

On to step 13:
406 can be fit into 1880 4 times, resulting in a remainder of 256.
Put 4 as the next digit of the answer. 
Result so far: 38884.65024
If we take 1624 away from 1880, we end up with 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Advancing to step 14:
406 goes into 2560 6 times with a remainder of 124.
The number 6 becomes the next digit in our result. 
Result so far: 38884.650246
Subtract 2436 from 2560 to get 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

On to step 15:
406 can be fit into 1240 3 times, resulting in a remainder of 22.
Write down 3 as next digit of the result. 
Result so far: 38884.6502463
If we take 1218 away from 1240, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 16:
The number 406 fits into 220 0 times, leaving a remainder of 220.
The next digit of our result is 0. 
Result so far: 38884.6502463
The remainder is 220 after subtracting 0 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

The final result is 38884.6502463 with a remainder of 2.2e-07.
