48629233 divided by 407 
The aim is to understand the frequency of 407 in 48629233.

Let's proceed to step 1:
When dividing 4 by 407, we get 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Bring next digit (8) of the dividend behind the 4 and repeat the process: 48 / 407

Step 2:
If we divide 48 by 407, we get 0 and a remainder of 48.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 48 and we're left with 48.
Take the next digit (6) from the dividend and append it to 48, then repeat: 486 / 407

Let's proceed to step 3:
407 goes into 486 1 times with a remainder of 79.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 407 from 486, we get 79.
Include the next digit (2) from the dividend after 79, then repeat: 792 / 407

Going ahead to step 4:
The number 407 fits into 792 1 times, leaving a remainder of 385.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
Subtracting 407 from 792 leaves us with 385.
Fetch the next digit (9) from the dividend, attach it to 385 and continue: 3859 / 407

Going ahead to step 5:
407 goes into 3859 9 times with a remainder of 196.
Put 9 as the next digit of the answer. 
Result so far: 119.0
Deduct 3663 from 3859 and we're left with 196.
Fetch the next digit (2) from the dividend, attach it to 196 and continue: 1962 / 407

Going ahead to step 6:
If we divide 1962 by 407, we get 4 and a remainder of 334.
Write down 4 as next digit of the result. 
Result so far: 1194.0
If we take 1628 away from 1962, we end up with 334.
Take the next digit (3) from the dividend and append it to 334, then repeat: 3343 / 407

Advancing to step 7:
407 goes into 3343 8 times with a remainder of 87.
Use 8 as the next digit of our solution. 
Result so far: 11948.0
The remainder is 87 after subtracting 3256 from 3343.
Append the next digit (3) from the dividend to 87 and continue with: 873 / 407

Let's proceed to step 8:
The number 407 fits into 873 2 times, leaving a remainder of 59.
Use 2 as the next digit of our solution. 
Result so far: 119482.0
If we subtract 814 from 873, we get 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Let's proceed to step 9:
When dividing 590 by 407, we get 1 with a remainder of 183.
The next digit of our result is 1. 
Result so far: 119482.1
If we subtract 407 from 590, we get 183.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1830, and continue the process.

On to step 10:
407 can be fit into 1830 4 times, resulting in a remainder of 202.
Record the quotient 4 as the next digit in the result. 
Result so far: 119482.14
Subtract 1628 from 1830 to get 202.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2020, and continue the process.

Step 11:
407 can be fit into 2020 4 times, resulting in a remainder of 392.
The number 4 becomes the next digit in our result. 
Result so far: 119482.144
Subtracting 1628 from 2020 leaves us with 392.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3920, and continue the process.

The quotient of the division is 119482.144, and the remainder is 0.0392.
