We divide 43212705 by 491
The aim is to understand the frequency of 491 in 43212705.

On to step 1:
491 goes into 4 0 times with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Bring next digit (3) of the dividend behind the 4 and repeat the process: 43 / 491

Let's proceed to step 2:
491 can be fit into 43 0 times, resulting in a remainder of 43.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 43 to get 43.
Grab the next digit (2) from the dividend, add it to 43, then carry on: 432 / 491

Let's proceed to step 3:
If we divide 432 by 491, we get 0 and a remainder of 432.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 432 leaves us with 432.
Grab the next digit (1) from the dividend, add it to 432, then carry on: 4321 / 491

Advancing to step 4:
The number 491 fits into 4321 8 times, leaving a remainder of 393.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
If we subtract 3928 from 4321, we get 393.
Fetch the next digit (2) from the dividend, attach it to 393 and continue: 3932 / 491

Going ahead to step 5:
If we divide 3932 by 491, we get 8 and a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 88.0
Deduct 3928 from 3932 and we're left with 4.
Take the next digit (7) from the dividend and append it to 4, then repeat: 47 / 491

Going ahead to step 6:
47 divided by 491 is 0 with a remainder of 47.
Write down 0 as next digit of the result. 
Result so far: 880.0
Subtracting 0 from 47 leaves us with 47.
Fetch the next digit (0) from the dividend, attach it to 47 and continue: 470 / 491

Let's proceed to step 7:
470 divided by 491 is 0 with a remainder of 470.
Record the quotient 0 as the next digit in the result. 
Result so far: 8800.0
Deduct 0 from 470 and we're left with 470.
Take the next digit (5) from the dividend and append it to 470, then repeat: 4705 / 491

Step 8:
When dividing 4705 by 491, we get 9 with a remainder of 286.
Record the quotient 9 as the next digit in the result. 
Result so far: 88009.0
If we take 4419 away from 4705, we end up with 286.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2860, and continue the process.

Moving on to step 9:
The number 491 fits into 2860 5 times, leaving a remainder of 405.
Put 5 as the next digit of the answer. 
Result so far: 88009.5
Deduct 2455 from 2860 and we're left with 405.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4050, and continue the process.

Advancing to step 10:
491 goes into 4050 8 times with a remainder of 122.
Use 8 as the next digit of our solution. 
Result so far: 88009.58
If we subtract 3928 from 4050, we get 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

Step 11:
491 goes into 1220 2 times with a remainder of 238.
The next digit of our result is 2. 
Result so far: 88009.582
If we take 982 away from 1220, we end up with 238.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2380, and continue the process.

Moving on to step 12:
2380 divided by 491 is 4 with a remainder of 416.
Use 4 as the next digit of our solution. 
Result so far: 88009.5824
Deduct 1964 from 2380 and we're left with 416.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

Going ahead to step 13:
When dividing 4160 by 491, we get 8 with a remainder of 232.
Record the quotient 8 as the next digit in the result. 
Result so far: 88009.58248
If we take 3928 away from 4160, we end up with 232.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

On to step 14:
491 can be fit into 2320 4 times, resulting in a remainder of 356.
The next digit of our result is 4. 
Result so far: 88009.582484
Subtracting 1964 from 2320 leaves us with 356.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3560, and continue the process.

Advancing to step 15:
491 goes into 3560 7 times with a remainder of 123.
Use 7 as the next digit of our solution. 
Result so far: 88009.5824847
If we take 3437 away from 3560, we end up with 123.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1230, and continue the process.

Advancing to step 16:
1230 divided by 491 is 2 with a remainder of 248.
Write down 2 as next digit of the result. 
Result so far: 88009.58248472
Subtracting 982 from 1230 leaves us with 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

Our division results in 88009.58248472 with a remaining 2.48e-07.
