39271522 ÷ 439 
The aim is to understand the frequency of 439 in 39271522.

On to step 1:
3 divided by 439 is 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 439

On to step 2:
439 can be fit into 39 0 times, resulting in a remainder of 39.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 39 after subtracting 0 from 39.
Append the next digit (2) from the dividend to 39 and continue with: 392 / 439

Advancing to step 3:
439 can be fit into 392 0 times, resulting in a remainder of 392.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 392, we end up with 392.
Take the next digit (7) from the dividend and append it to 392, then repeat: 3927 / 439

On to step 4:
The number 439 fits into 3927 8 times, leaving a remainder of 415.
The next digit of our result is 8. 
Result so far: 8.0
The remainder is 415 after subtracting 3512 from 3927.
Fetch the next digit (1) from the dividend, attach it to 415 and continue: 4151 / 439

Going ahead to step 5:
When dividing 4151 by 439, we get 9 with a remainder of 200.
The number 9 becomes the next digit in our result. 
Result so far: 89.0
Deduct 3951 from 4151 and we're left with 200.
Grab the next digit (5) from the dividend, add it to 200, then carry on: 2005 / 439

Step 6:
2005 divided by 439 is 4 with a remainder of 249.
The next digit of our result is 4. 
Result so far: 894.0
If we subtract 1756 from 2005, we get 249.
Fetch the next digit (2) from the dividend, attach it to 249 and continue: 2492 / 439

Going ahead to step 7:
When dividing 2492 by 439, we get 5 with a remainder of 297.
Put 5 as the next digit of the answer. 
Result so far: 8945.0
Deduct 2195 from 2492 and we're left with 297.
Take the next digit (2) from the dividend and append it to 297, then repeat: 2972 / 439

Going ahead to step 8:
2972 divided by 439 is 6 with a remainder of 338.
The next digit of our result is 6. 
Result so far: 89456.0
Subtract 2634 from 2972 to get 338.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3380, and continue the process.

On to step 9:
The number 439 fits into 3380 7 times, leaving a remainder of 307.
Record the quotient 7 as the next digit in the result. 
Result so far: 89456.7
Subtract 3073 from 3380 to get 307.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3070, and continue the process.

Advancing to step 10:
If we divide 3070 by 439, we get 6 and a remainder of 436.
Put 6 as the next digit of the answer. 
Result so far: 89456.76
Subtract 2634 from 3070 to get 436.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4360, and continue the process.

On to step 11:
If we divide 4360 by 439, we get 9 and a remainder of 409.
The number 9 becomes the next digit in our result. 
Result so far: 89456.769
If we subtract 3951 from 4360, we get 409.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4090, and continue the process.

Advancing to step 12:
If we divide 4090 by 439, we get 9 and a remainder of 139.
Record the quotient 9 as the next digit in the result. 
Result so far: 89456.7699
Deduct 3951 from 4090 and we're left with 139.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1390, and continue the process.

Our division results in 89456.7699 with a remaining 0.00139.
