Let's divide 37548731 by 407
The aim is to understand the frequency of 407 in 37548731.

Going ahead to step 1:
407 can be fit into 3 0 times, resulting in a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Include the next digit (7) from the dividend after 3, then repeat: 37 / 407

Going ahead to step 2:
37 divided by 407 is 0 with a remainder of 37.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 37 and we're left with 37.
Fetch the next digit (5) from the dividend, attach it to 37 and continue: 375 / 407

Moving on to step 3:
The number 407 fits into 375 0 times, leaving a remainder of 375.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 375 and we're left with 375.
Bring next digit (4) of the dividend behind the 375 and repeat the process: 3754 / 407

Step 4:
When dividing 3754 by 407, we get 9 with a remainder of 91.
The next digit of our result is 9. 
Result so far: 9.0
The remainder is 91 after subtracting 3663 from 3754.
Append the next digit (8) from the dividend to 91 and continue with: 918 / 407

Advancing to step 5:
407 can be fit into 918 2 times, resulting in a remainder of 104.
Write down 2 as next digit of the result. 
Result so far: 92.0
The remainder is 104 after subtracting 814 from 918.
Grab the next digit (7) from the dividend, add it to 104, then carry on: 1047 / 407

On to step 6:
1047 divided by 407 is 2 with a remainder of 233.
Write down 2 as next digit of the result. 
Result so far: 922.0
Subtract 814 from 1047 to get 233.
Fetch the next digit (3) from the dividend, attach it to 233 and continue: 2333 / 407

Let's proceed to step 7:
When dividing 2333 by 407, we get 5 with a remainder of 298.
Put 5 as the next digit of the answer. 
Result so far: 9225.0
If we take 2035 away from 2333, we end up with 298.
Fetch the next digit (1) from the dividend, attach it to 298 and continue: 2981 / 407

On to step 8:
407 can be fit into 2981 7 times, resulting in a remainder of 132.
Use 7 as the next digit of our solution. 
Result so far: 92257.0
Subtracting 2849 from 2981 leaves us with 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Let's proceed to step 9:
When dividing 1320 by 407, we get 3 with a remainder of 99.
Put 3 as the next digit of the answer. 
Result so far: 92257.3
Subtracting 1221 from 1320 leaves us with 99.
Since there are no more digits in the dividend, we add a zero to the remainder making it 990, and continue the process.

Step 10:
407 can be fit into 990 2 times, resulting in a remainder of 176.
Use 2 as the next digit of our solution. 
Result so far: 92257.32
Subtract 814 from 990 to get 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Moving on to step 11:
When dividing 1760 by 407, we get 4 with a remainder of 132.
Write down 4 as next digit of the result. 
Result so far: 92257.324
The remainder is 132 after subtracting 1628 from 1760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

On to step 12:
If we divide 1320 by 407, we get 3 and a remainder of 99.
The number 3 becomes the next digit in our result. 
Result so far: 92257.3243
Subtracting 1221 from 1320 leaves us with 99.
Since there are no more digits in the dividend, we add a zero to the remainder making it 990, and continue the process.

Let's proceed to step 13:
407 goes into 990 2 times with a remainder of 176.
The next digit of our result is 2. 
Result so far: 92257.32432
If we subtract 814 from 990, we get 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Step 14:
The number 407 fits into 1760 4 times, leaving a remainder of 132.
The next digit of our result is 4. 
Result so far: 92257.324324
Deduct 1628 from 1760 and we're left with 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Moving on to step 15:
1320 divided by 407 is 3 with a remainder of 99.
Write down 3 as next digit of the result. 
Result so far: 92257.3243243
If we subtract 1221 from 1320, we get 99.
Since there are no more digits in the dividend, we add a zero to the remainder making it 990, and continue the process.

Going ahead to step 16:
990 divided by 407 is 2 with a remainder of 176.
Put 2 as the next digit of the answer. 
Result so far: 92257.32432432
Subtracting 814 from 990 leaves us with 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

The quotient of the division is 92257.32432432, and the remainder is 1.76e-07.
