64460035 ÷ 404 
The aim is to understand the frequency of 404 in 64460035.

On to step 1:
If we divide 6 by 404, we get 0 and a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 404

Moving on to step 2:
The number 404 fits into 64 0 times, leaving a remainder of 64.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 64, we get 64.
Fetch the next digit (4) from the dividend, attach it to 64 and continue: 644 / 404

On to step 3:
644 divided by 404 is 1 with a remainder of 240.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 240 after subtracting 404 from 644.
Grab the next digit (6) from the dividend, add it to 240, then carry on: 2406 / 404

Moving on to step 4:
404 goes into 2406 5 times with a remainder of 386.
Use 5 as the next digit of our solution. 
Result so far: 15.0
The remainder is 386 after subtracting 2020 from 2406.
Fetch the next digit (0) from the dividend, attach it to 386 and continue: 3860 / 404

Advancing to step 5:
When dividing 3860 by 404, we get 9 with a remainder of 224.
Put 9 as the next digit of the answer. 
Result so far: 159.0
The remainder is 224 after subtracting 3636 from 3860.
Fetch the next digit (0) from the dividend, attach it to 224 and continue: 2240 / 404

Step 6:
If we divide 2240 by 404, we get 5 and a remainder of 220.
The next digit of our result is 5. 
Result so far: 1595.0
If we take 2020 away from 2240, we end up with 220.
Grab the next digit (3) from the dividend, add it to 220, then carry on: 2203 / 404

On to step 7:
404 can be fit into 2203 5 times, resulting in a remainder of 183.
Put 5 as the next digit of the answer. 
Result so far: 15955.0
Subtract 2020 from 2203 to get 183.
Include the next digit (5) from the dividend after 183, then repeat: 1835 / 404

Advancing to step 8:
1835 divided by 404 is 4 with a remainder of 219.
Write down 4 as next digit of the result. 
Result so far: 159554.0
If we subtract 1616 from 1835, 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 9:
The number 404 fits into 2190 5 times, leaving a remainder of 170.
The next digit of our result is 5. 
Result so far: 159554.5
Subtract 2020 from 2190 to get 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Let's proceed to step 10:
When dividing 1700 by 404, we get 4 with a remainder of 84.
Record the quotient 4 as the next digit in the result. 
Result so far: 159554.54
The remainder is 84 after subtracting 1616 from 1700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

On to step 11:
If we divide 840 by 404, we get 2 and a remainder of 32.
The number 2 becomes the next digit in our result. 
Result so far: 159554.542
Deduct 808 from 840 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 12:
404 can be fit into 320 0 times, resulting in a remainder of 320.
Put 0 as the next digit of the answer. 
Result so far: 159554.542
If we subtract 0 from 320, we get 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

On to step 13:
The number 404 fits into 3200 7 times, leaving a remainder of 372.
The number 7 becomes the next digit in our result. 
Result so far: 159554.54207
The remainder is 372 after subtracting 2828 from 3200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3720, and continue the process.

Let's proceed to step 14:
The number 404 fits into 3720 9 times, leaving a remainder of 84.
Write down 9 as next digit of the result. 
Result so far: 159554.542079
Subtract 3636 from 3720 to get 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Step 15:
404 can be fit into 840 2 times, resulting in a remainder of 32.
Record the quotient 2 as the next digit in the result. 
Result so far: 159554.5420792
The remainder is 32 after subtracting 808 from 840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 16:
The number 404 fits into 320 0 times, leaving a remainder of 320.
The next digit of our result is 0. 
Result so far: 159554.5420792
If we take 0 away from 320, we end up with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

In conclusion, the division gives 159554.5420792 with a balance of 3.2e-07.
