40095080 ÷ 423 
The aim is to understand the frequency of 423 in 40095080.

Advancing to step 1:
423 goes into 4 0 times with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Grab the next digit (0) from the dividend, add it to 4, then carry on: 40 / 423

Step 2:
423 goes into 40 0 times with a remainder of 40.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 40 after subtracting 0 from 40.
Take the next digit (0) from the dividend and append it to 40, then repeat: 400 / 423

Going ahead to step 3:
423 goes into 400 0 times with a remainder of 400.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 400 after subtracting 0 from 400.
Include the next digit (9) from the dividend after 400, then repeat: 4009 / 423

Let's proceed to step 4:
If we divide 4009 by 423, we get 9 and a remainder of 202.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
If we subtract 3807 from 4009, we get 202.
Grab the next digit (5) from the dividend, add it to 202, then carry on: 2025 / 423

On to step 5:
The number 423 fits into 2025 4 times, leaving a remainder of 333.
The number 4 becomes the next digit in our result. 
Result so far: 94.0
If we subtract 1692 from 2025, we get 333.
Take the next digit (0) from the dividend and append it to 333, then repeat: 3330 / 423

Let's proceed to step 6:
3330 divided by 423 is 7 with a remainder of 369.
Record the quotient 7 as the next digit in the result. 
Result so far: 947.0
If we subtract 2961 from 3330, we get 369.
Take the next digit (8) from the dividend and append it to 369, then repeat: 3698 / 423

On to step 7:
423 goes into 3698 8 times with a remainder of 314.
Write down 8 as next digit of the result. 
Result so far: 9478.0
Subtract 3384 from 3698 to get 314.
Fetch the next digit (0) from the dividend, attach it to 314 and continue: 3140 / 423

Going ahead to step 8:
If we divide 3140 by 423, we get 7 and a remainder of 179.
Put 7 as the next digit of the answer. 
Result so far: 94787.0
If we take 2961 away from 3140, we end up with 179.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1790, and continue the process.

Moving on to step 9:
When dividing 1790 by 423, we get 4 with a remainder of 98.
The next digit of our result is 4. 
Result so far: 94787.4
The remainder is 98 after subtracting 1692 from 1790.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

Let's proceed to step 10:
423 goes into 980 2 times with a remainder of 134.
Use 2 as the next digit of our solution. 
Result so far: 94787.42
The remainder is 134 after subtracting 846 from 980.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

Step 11:
423 can be fit into 1340 3 times, resulting in a remainder of 71.
The number 3 becomes the next digit in our result. 
Result so far: 94787.423
Subtracting 1269 from 1340 leaves us with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

On to step 12:
When dividing 710 by 423, we get 1 with a remainder of 287.
Use 1 as the next digit of our solution. 
Result so far: 94787.4231
Deduct 423 from 710 and we're left with 287.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2870, and continue the process.

Let's proceed to step 13:
423 can be fit into 2870 6 times, resulting in a remainder of 332.
The next digit of our result is 6. 
Result so far: 94787.42316
Subtract 2538 from 2870 to get 332.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3320, and continue the process.

Moving on to step 14:
When dividing 3320 by 423, we get 7 with a remainder of 359.
Use 7 as the next digit of our solution. 
Result so far: 94787.423167
Subtract 2961 from 3320 to get 359.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3590, and continue the process.

On to step 15:
423 can be fit into 3590 8 times, resulting in a remainder of 206.
Record the quotient 8 as the next digit in the result. 
Result so far: 94787.4231678
If we subtract 3384 from 3590, we get 206.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2060, and continue the process.

Going ahead to step 16:
If we divide 2060 by 423, we get 4 and a remainder of 368.
Put 4 as the next digit of the answer. 
Result so far: 94787.42316784
If we take 1692 away from 2060, we end up with 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

After the division, we end up with 94787.42316784 and a remainder of 3.68e-07.
