We divide 64104590 by 439
The aim is to understand the frequency of 439 in 64104590.

On to step 1:
439 can be fit into 6 0 times, resulting in a remainder of 6.
The number 0 becomes the next digit in our result. 
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 / 439

Step 2:
The number 439 fits into 64 0 times, leaving a remainder of 64.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 64 after subtracting 0 from 64.
Append the next digit (1) from the dividend to 64 and continue with: 641 / 439

On to step 3:
The number 439 fits into 641 1 times, leaving a remainder of 202.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 439 away from 641, we end up with 202.
Append the next digit (0) from the dividend to 202 and continue with: 2020 / 439

Step 4:
If we divide 2020 by 439, we get 4 and a remainder of 264.
Write down 4 as next digit of the result. 
Result so far: 14.0
The remainder is 264 after subtracting 1756 from 2020.
Fetch the next digit (4) from the dividend, attach it to 264 and continue: 2644 / 439

Step 5:
439 can be fit into 2644 6 times, resulting in a remainder of 10.
Use 6 as the next digit of our solution. 
Result so far: 146.0
Deduct 2634 from 2644 and we're left with 10.
Include the next digit (5) from the dividend after 10, then repeat: 105 / 439

Moving on to step 6:
When dividing 105 by 439, we get 0 with a remainder of 105.
The next digit of our result is 0. 
Result so far: 1460.0
The remainder is 105 after subtracting 0 from 105.
Grab the next digit (9) from the dividend, add it to 105, then carry on: 1059 / 439

Going ahead to step 7:
If we divide 1059 by 439, we get 2 and a remainder of 181.
Use 2 as the next digit of our solution. 
Result so far: 14602.0
If we take 878 away from 1059, we end up with 181.
Take the next digit (0) from the dividend and append it to 181, then repeat: 1810 / 439

Going ahead to step 8:
The number 439 fits into 1810 4 times, leaving a remainder of 54.
The number 4 becomes the next digit in our result. 
Result so far: 146024.0
Deduct 1756 from 1810 and we're left with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Going ahead to step 9:
When dividing 540 by 439, we get 1 with a remainder of 101.
Use 1 as the next digit of our solution. 
Result so far: 146024.1
Deduct 439 from 540 and we're left with 101.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1010, and continue the process.

Going ahead to step 10:
The number 439 fits into 1010 2 times, leaving a remainder of 132.
Put 2 as the next digit of the answer. 
Result so far: 146024.12
The remainder is 132 after subtracting 878 from 1010.
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 11:
1320 divided by 439 is 3 with a remainder of 3.
The number 3 becomes the next digit in our result. 
Result so far: 146024.123
Subtracting 1317 from 1320 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 12:
The number 439 fits into 30 0 times, leaving a remainder of 30.
The next digit of our result is 0. 
Result so far: 146024.123
If we take 0 away from 30, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 13:
The number 439 fits into 300 0 times, leaving a remainder of 300.
Put 0 as the next digit of the answer. 
Result so far: 146024.123
Subtract 0 from 300 to get 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

The quotient of the division is 146024.123, and the remainder is 0.0003.
