We divide 25152864 by 861
The aim is to understand the frequency of 861 in 25152864.

Advancing to step 1:
861 goes into 2 0 times with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Take the next digit (5) from the dividend and append it to 2, then repeat: 25 / 861

Going ahead to step 2:
25 divided by 861 is 0 with a remainder of 25.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 25, we end up with 25.
Append the next digit (1) from the dividend to 25 and continue with: 251 / 861

Let's proceed to step 3:
When dividing 251 by 861, we get 0 with a remainder of 251.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 251 after subtracting 0 from 251.
Take the next digit (5) from the dividend and append it to 251, then repeat: 2515 / 861

On to step 4:
2515 divided by 861 is 2 with a remainder of 793.
The next digit of our result is 2. 
Result so far: 2.0
Subtracting 1722 from 2515 leaves us with 793.
Grab the next digit (2) from the dividend, add it to 793, then carry on: 7932 / 861

On to step 5:
If we divide 7932 by 861, we get 9 and a remainder of 183.
The number 9 becomes the next digit in our result. 
Result so far: 29.0
The remainder is 183 after subtracting 7749 from 7932.
Grab the next digit (8) from the dividend, add it to 183, then carry on: 1838 / 861

Going ahead to step 6:
The number 861 fits into 1838 2 times, leaving a remainder of 116.
The next digit of our result is 2. 
Result so far: 292.0
Deduct 1722 from 1838 and we're left with 116.
Fetch the next digit (6) from the dividend, attach it to 116 and continue: 1166 / 861

Step 7:
When dividing 1166 by 861, we get 1 with a remainder of 305.
Use 1 as the next digit of our solution. 
Result so far: 2921.0
Subtracting 861 from 1166 leaves us with 305.
Fetch the next digit (4) from the dividend, attach it to 305 and continue: 3054 / 861

Going ahead to step 8:
3054 divided by 861 is 3 with a remainder of 471.
Use 3 as the next digit of our solution. 
Result so far: 29213.0
Subtracting 2583 from 3054 leaves us with 471.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4710, and continue the process.

Moving on to step 9:
The number 861 fits into 4710 5 times, leaving a remainder of 405.
Use 5 as the next digit of our solution. 
Result so far: 29213.5
Subtracting 4305 from 4710 leaves us 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:
When dividing 4050 by 861, we get 4 with a remainder of 606.
Record the quotient 4 as the next digit in the result. 
Result so far: 29213.54
If we take 3444 away from 4050, we end up with 606.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6060, and continue the process.

On to step 11:
If we divide 6060 by 861, we get 7 and a remainder of 33.
Use 7 as the next digit of our solution. 
Result so far: 29213.547
Deduct 6027 from 6060 and we're left with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

On to step 12:
The number 861 fits into 330 0 times, leaving a remainder of 330.
The number 0 becomes the next digit in our result. 
Result so far: 29213.547
If we take 0 away from 330, we end up 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.

Advancing to step 13:
When dividing 3300 by 861, we get 3 with a remainder of 717.
The next digit of our result is 3. 
Result so far: 29213.54703
The remainder is 717 after subtracting 2583 from 3300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7170, and continue the process.

Moving on to step 14:
861 goes into 7170 8 times with a remainder of 282.
Record the quotient 8 as the next digit in the result. 
Result so far: 29213.547038
Subtract 6888 from 7170 to get 282.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2820, and continue the process.

Moving on to step 15:
861 goes into 2820 3 times with a remainder of 237.
The next digit of our result is 3. 
Result so far: 29213.5470383
If we take 2583 away from 2820, we end up with 237.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2370, and continue the process.

Step 16:
861 can be fit into 2370 2 times, resulting in a remainder of 648.
The next digit of our result is 2. 
Result so far: 29213.54703832
Subtracting 1722 from 2370 leaves us with 648.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6480, and continue the process.

The final result is 29213.54703832 with a remainder of 6.48e-07.
