We're dividing 37942099 by 408 
The aim is to understand the frequency of 408 in 37942099.

Moving on to step 1:
The number 408 fits into 3 0 times, leaving a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Take the next digit (7) from the dividend and append it to 3, then repeat: 37 / 408

Going ahead to step 2:
37 divided by 408 is 0 with a remainder of 37.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 37 and we're left with 37.
Append the next digit (9) from the dividend to 37 and continue with: 379 / 408

Advancing to step 3:
408 can be fit into 379 0 times, resulting in a remainder of 379.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 379 and we're left with 379.
Fetch the next digit (4) from the dividend, attach it to 379 and continue: 3794 / 408

On to step 4:
If we divide 3794 by 408, we get 9 and a remainder of 122.
Write down 9 as next digit of the result. 
Result so far: 9.0
If we take 3672 away from 3794, we end up with 122.
Append the next digit (2) from the dividend to 122 and continue with: 1222 / 408

On to step 5:
408 goes into 1222 2 times with a remainder of 406.
The number 2 becomes the next digit in our result. 
Result so far: 92.0
The remainder is 406 after subtracting 816 from 1222.
Include the next digit (0) from the dividend after 406, then repeat: 4060 / 408

Step 6:
If we divide 4060 by 408, we get 9 and a remainder of 388.
The next digit of our result is 9. 
Result so far: 929.0
Subtract 3672 from 4060 to get 388.
Grab the next digit (9) from the dividend, add it to 388, then carry on: 3889 / 408

Going ahead to step 7:
408 can be fit into 3889 9 times, resulting in a remainder of 217.
The number 9 becomes the next digit in our result. 
Result so far: 9299.0
The remainder is 217 after subtracting 3672 from 3889.
Take the next digit (9) from the dividend and append it to 217, then repeat: 2179 / 408

Moving on to step 8:
When dividing 2179 by 408, we get 5 with a remainder of 139.
Write down 5 as next digit of the result. 
Result so far: 92995.0
If we take 2040 away from 2179, we end up with 139.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1390, and continue the process.

Going ahead to step 9:
1390 divided by 408 is 3 with a remainder of 166.
The number 3 becomes the next digit in our result. 
Result so far: 92995.3
Subtracting 1224 from 1390 leaves us with 166.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1660, and continue the process.

Step 10:
408 can be fit into 1660 4 times, resulting in a remainder of 28.
Use 4 as the next digit of our solution. 
Result so far: 92995.34
The remainder is 28 after subtracting 1632 from 1660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 11:
408 can be fit into 280 0 times, resulting in a remainder of 280.
Write down 0 as next digit of the result. 
Result so far: 92995.34
If we subtract 0 from 280, we get 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Advancing to step 12:
2800 divided by 408 is 6 with a remainder of 352.
Use 6 as the next digit of our solution. 
Result so far: 92995.3406
Subtract 2448 from 2800 to get 352.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

Step 13:
If we divide 3520 by 408, we get 8 and a remainder of 256.
Write down 8 as next digit of the result. 
Result so far: 92995.34068
If we subtract 3264 from 3520, we get 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Let's proceed to step 14:
The number 408 fits into 2560 6 times, leaving a remainder of 112.
Use 6 as the next digit of our solution. 
Result so far: 92995.340686
If we take 2448 away from 2560, we end up with 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

On to step 15:
408 can be fit into 1120 2 times, resulting in a remainder of 304.
The number 2 becomes the next digit in our result. 
Result so far: 92995.3406862
The remainder is 304 after subtracting 816 from 1120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

On to step 16:
The number 408 fits into 3040 7 times, leaving a remainder of 184.
The next digit of our result is 7. 
Result so far: 92995.34068627
The remainder is 184 after subtracting 2856 from 3040.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

The final outcome is 92995.34068627, with a leftover of 1.84e-07.
