Let's divide 98753599 by 407
The aim is to understand the frequency of 407 in 98753599.

Advancing to step 1:
9 divided by 407 is 0 with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Include the next digit (8) from the dividend after 9, then repeat: 98 / 407

Advancing to step 2:
If we divide 98 by 407, we get 0 and a remainder of 98.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 98, we end up with 98.
Append the next digit (7) from the dividend to 98 and continue with: 987 / 407

Advancing to step 3:
407 can be fit into 987 2 times, resulting in a remainder of 173.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Deduct 814 from 987 and we're left with 173.
Fetch the next digit (5) from the dividend, attach it to 173 and continue: 1735 / 407

Going ahead to step 4:
407 goes into 1735 4 times with a remainder of 107.
The number 4 becomes the next digit in our result. 
Result so far: 24.0
Deduct 1628 from 1735 and we're left with 107.
Include the next digit (3) from the dividend after 107, then repeat: 1073 / 407

Going ahead to step 5:
If we divide 1073 by 407, we get 2 and a remainder of 259.
The number 2 becomes the next digit in our result. 
Result so far: 242.0
If we take 814 away from 1073, we end up with 259.
Fetch the next digit (5) from the dividend, attach it to 259 and continue: 2595 / 407

Advancing to step 6:
The number 407 fits into 2595 6 times, leaving a remainder of 153.
The next digit of our result is 6. 
Result so far: 2426.0
The remainder is 153 after subtracting 2442 from 2595.
Include the next digit (9) from the dividend after 153, then repeat: 1539 / 407

Let's proceed to step 7:
When dividing 1539 by 407, we get 3 with a remainder of 318.
The number 3 becomes the next digit in our result. 
Result so far: 24263.0
Subtract 1221 from 1539 to get 318.
Bring next digit (9) of the dividend behind the 318 and repeat the process: 3189 / 407

Going ahead to step 8:
If we divide 3189 by 407, we get 7 and a remainder of 340.
The next digit of our result is 7. 
Result so far: 242637.0
If we subtract 2849 from 3189, we get 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Going ahead to step 9:
When dividing 3400 by 407, we get 8 with a remainder of 144.
Write down 8 as next digit of the result. 
Result so far: 242637.8
Deduct 3256 from 3400 and we're left with 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

On to step 10:
If we divide 1440 by 407, we get 3 and a remainder of 219.
Use 3 as the next digit of our solution. 
Result so far: 242637.83
If we subtract 1221 from 1440, we get 219.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2190, and continue the process.

Step 11:
407 goes into 2190 5 times with a remainder of 155.
Write down 5 as next digit of the result. 
Result so far: 242637.835
If we subtract 2035 from 2190, we get 155.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

Advancing to step 12:
The number 407 fits into 1550 3 times, leaving a remainder of 329.
Use 3 as the next digit of our solution. 
Result so far: 242637.8353
Subtract 1221 from 1550 to get 329.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3290, and continue the process.

Going ahead to step 13:
3290 divided by 407 is 8 with a remainder of 34.
Put 8 as the next digit of the answer. 
Result so far: 242637.83538
Subtracting 3256 from 3290 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 14:
407 goes into 340 0 times with a remainder of 340.
Use 0 as the next digit of our solution. 
Result so far: 242637.83538
The remainder is 340 after subtracting 0 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Step 15:
407 can be fit into 3400 8 times, resulting in a remainder of 144.
Write down 8 as next digit of the result. 
Result so far: 242637.8353808
Subtracting 3256 from 3400 leaves us with 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Advancing to step 16:
When dividing 1440 by 407, we get 3 with a remainder of 219.
Write down 3 as next digit of the result. 
Result so far: 242637.83538083
Deduct 1221 from 1440 and we're left with 219.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2190, and continue the process.

In conclusion, the division gives 242637.83538083 with a balance of 2.19e-07.
