We're dividing 76038566 by 407 
The aim is to understand the frequency of 407 in 76038566.

Moving on to step 1:
7 divided by 407 is 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Take the next digit (6) from the dividend and append it to 7, then repeat: 76 / 407

On to step 2:
When dividing 76 by 407, we get 0 with a remainder of 76.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 76 leaves us with 76.
Include the next digit (0) from the dividend after 76, then repeat: 760 / 407

On to step 3:
If we divide 760 by 407, we get 1 and a remainder of 353.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 407 from 760 and we're left with 353.
Grab the next digit (3) from the dividend, add it to 353, then carry on: 3533 / 407

On to step 4:
If we divide 3533 by 407, we get 8 and a remainder of 277.
Write down 8 as next digit of the result. 
Result so far: 18.0
If we take 3256 away from 3533, we end up with 277.
Include the next digit (8) from the dividend after 277, then repeat: 2778 / 407

Advancing to step 5:
If we divide 2778 by 407, we get 6 and a remainder of 336.
Put 6 as the next digit of the answer. 
Result so far: 186.0
The remainder is 336 after subtracting 2442 from 2778.
Include the next digit (5) from the dividend after 336, then repeat: 3365 / 407

Going ahead to step 6:
3365 divided by 407 is 8 with a remainder of 109.
The number 8 becomes the next digit in our result. 
Result so far: 1868.0
Deduct 3256 from 3365 and we're left with 109.
Grab the next digit (6) from the dividend, add it to 109, then carry on: 1096 / 407

Moving on to step 7:
When dividing 1096 by 407, we get 2 with a remainder of 282.
The next digit of our result is 2. 
Result so far: 18682.0
Subtract 814 from 1096 to get 282.
Bring next digit (6) of the dividend behind the 282 and repeat the process: 2826 / 407

Let's proceed to step 8:
When dividing 2826 by 407, we get 6 with a remainder of 384.
The number 6 becomes the next digit in our result. 
Result so far: 186826.0
If we take 2442 away from 2826, we end up with 384.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

Moving on to step 9:
407 goes into 3840 9 times with a remainder of 177.
The next digit of our result is 9. 
Result so far: 186826.9
The remainder is 177 after subtracting 3663 from 3840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1770, and continue the process.

Step 10:
When dividing 1770 by 407, we get 4 with a remainder of 142.
Write down 4 as next digit of the result. 
Result so far: 186826.94
The remainder is 142 after subtracting 1628 from 1770.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1420, and continue the process.

Going ahead to step 11:
When dividing 1420 by 407, we get 3 with a remainder of 199.
The next digit of our result is 3. 
Result so far: 186826.943
If we subtract 1221 from 1420, we get 199.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1990, and continue the process.

Advancing to step 12:
The number 407 fits into 1990 4 times, leaving a remainder of 362.
The number 4 becomes the next digit in our result. 
Result so far: 186826.9434
Deduct 1628 from 1990 and we're left with 362.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3620, and continue the process.

Going ahead to step 13:
If we divide 3620 by 407, we get 8 and a remainder of 364.
Use 8 as the next digit of our solution. 
Result so far: 186826.94348
The remainder is 364 after subtracting 3256 from 3620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3640, and continue the process.

On to step 14:
If we divide 3640 by 407, we get 8 and a remainder of 384.
Put 8 as the next digit of the answer. 
Result so far: 186826.943488
Subtract 3256 from 3640 to get 384.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

Our division results in 186826.943488 with a remaining 3.84e-05.
