We divide 12487211 by 452
The aim is to understand the frequency of 452 in 12487211.

Going ahead to step 1:
1 divided by 452 is 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 452

Moving on to step 2:
452 goes into 12 0 times with a remainder of 12.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 12 and we're left with 12.
Take the next digit (4) from the dividend and append it to 12, then repeat: 124 / 452

Moving on to step 3:
The number 452 fits into 124 0 times, leaving a remainder of 124.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 124, we end up with 124.
Grab the next digit (8) from the dividend, add it to 124, then carry on: 1248 / 452

Moving on to step 4:
When dividing 1248 by 452, we get 2 with a remainder of 344.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we subtract 904 from 1248, we get 344.
Include the next digit (7) from the dividend after 344, then repeat: 3447 / 452

Step 5:
The number 452 fits into 3447 7 times, leaving a remainder of 283.
The next digit of our result is 7. 
Result so far: 27.0
Deduct 3164 from 3447 and we're left with 283.
Bring next digit (2) of the dividend behind the 283 and repeat the process: 2832 / 452

Step 6:
If we divide 2832 by 452, we get 6 and a remainder of 120.
Record the quotient 6 as the next digit in the result. 
Result so far: 276.0
Deduct 2712 from 2832 and we're left with 120.
Take the next digit (1) from the dividend and append it to 120, then repeat: 1201 / 452

On to step 7:
If we divide 1201 by 452, we get 2 and a remainder of 297.
The next digit of our result is 2. 
Result so far: 2762.0
The remainder is 297 after subtracting 904 from 1201.
Append the next digit (1) from the dividend to 297 and continue with: 2971 / 452

Advancing to step 8:
The number 452 fits into 2971 6 times, leaving a remainder of 259.
Use 6 as the next digit of our solution. 
Result so far: 27626.0
If we subtract 2712 from 2971, we get 259.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2590, and continue the process.

Advancing to step 9:
452 can be fit into 2590 5 times, resulting in a remainder of 330.
Record the quotient 5 as the next digit in the result. 
Result so far: 27626.5
Deduct 2260 from 2590 and we're left with 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

Moving on to step 10:
The number 452 fits into 3300 7 times, leaving a remainder of 136.
Write down 7 as next digit of the result. 
Result so far: 27626.57
If we subtract 3164 from 3300, we get 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Advancing to step 11:
1360 divided by 452 is 3 with a remainder of 4.
Put 3 as the next digit of the answer. 
Result so far: 27626.573
If we subtract 1356 from 1360, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 12:
452 can be fit into 40 0 times, resulting in a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 27626.573
Deduct 0 from 40 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 13:
The number 452 fits into 400 0 times, leaving a remainder of 400.
The number 0 becomes the next digit in our result. 
Result so far: 27626.573
If we subtract 0 from 400, we get 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

The final result is 27626.573 with a remainder of 0.0004.
