92931008 ÷ 407 
The aim is to understand the frequency of 407 in 92931008.

Going ahead to step 1:
407 goes into 9 0 times with a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Append the next digit (2) from the dividend to 9 and continue with: 92 / 407

On to step 2:
If we divide 92 by 407, we get 0 and a remainder of 92.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 92, we get 92.
Take the next digit (9) from the dividend and append it to 92, then repeat: 929 / 407

Moving on to step 3:
407 can be fit into 929 2 times, resulting in a remainder of 115.
The next digit of our result is 2. 
Result so far: 2.0
Subtract 814 from 929 to get 115.
Take the next digit (3) from the dividend and append it to 115, then repeat: 1153 / 407

Moving on to step 4:
If we divide 1153 by 407, we get 2 and a remainder of 339.
Write down 2 as next digit of the result. 
Result so far: 22.0
If we subtract 814 from 1153, we get 339.
Bring next digit (1) of the dividend behind the 339 and repeat the process: 3391 / 407

Moving on to step 5:
The number 407 fits into 3391 8 times, leaving a remainder of 135.
Write down 8 as next digit of the result. 
Result so far: 228.0
The remainder is 135 after subtracting 3256 from 3391.
Append the next digit (0) from the dividend to 135 and continue with: 1350 / 407

Advancing to step 6:
The number 407 fits into 1350 3 times, leaving a remainder of 129.
Use 3 as the next digit of our solution. 
Result so far: 2283.0
Deduct 1221 from 1350 and we're left with 129.
Grab the next digit (0) from the dividend, add it to 129, then carry on: 1290 / 407

Let's proceed to step 7:
1290 divided by 407 is 3 with a remainder of 69.
Record the quotient 3 as the next digit in the result. 
Result so far: 22833.0
Deduct 1221 from 1290 and we're left with 69.
Fetch the next digit (8) from the dividend, attach it to 69 and continue: 698 / 407

On to step 8:
The number 407 fits into 698 1 times, leaving a remainder of 291.
Write down 1 as next digit of the result. 
Result so far: 228331.0
Subtracting 407 from 698 leaves us with 291.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2910, and continue the process.

On to step 9:
If we divide 2910 by 407, we get 7 and a remainder of 61.
The number 7 becomes the next digit in our result. 
Result so far: 228331.7
The remainder is 61 after subtracting 2849 from 2910.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Step 10:
When dividing 610 by 407, we get 1 with a remainder of 203.
The next digit of our result is 1. 
Result so far: 228331.71
If we take 407 away from 610, we end up with 203.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2030, and continue the process.

Going ahead to step 11:
2030 divided by 407 is 4 with a remainder of 402.
Put 4 as the next digit of the answer. 
Result so far: 228331.714
Subtract 1628 from 2030 to get 402.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4020, and continue the process.

On to step 12:
407 can be fit into 4020 9 times, resulting in a remainder of 357.
The next digit of our result is 9. 
Result so far: 228331.7149
Deduct 3663 from 4020 and we're left with 357.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3570, and continue the process.

Step 13:
The number 407 fits into 3570 8 times, leaving a remainder of 314.
The next digit of our result is 8. 
Result so far: 228331.71498
Subtract 3256 from 3570 to get 314.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3140, and continue the process.

Let's proceed to step 14:
If we divide 3140 by 407, we get 7 and a remainder of 291.
Use 7 as the next digit of our solution. 
Result so far: 228331.714987
Subtracting 2849 from 3140 leaves us with 291.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2910, and continue the process.

On to step 15:
2910 divided by 407 is 7 with a remainder of 61.
The next digit of our result is 7. 
Result so far: 228331.7149877
Subtract 2849 from 2910 to get 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

The final result is 228331.7149877 with a remainder of 6.1e-07.
