We divide 3965746 by 872
The aim is to understand the frequency of 872 in 3965746.

Advancing to step 1:
When dividing 3 by 872, we get 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Include the next digit (9) from the dividend after 3, then repeat: 39 / 872

Advancing to step 2:
The number 872 fits into 39 0 times, leaving a remainder of 39.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 39 and we're left with 39.
Grab the next digit (6) from the dividend, add it to 39, then carry on: 396 / 872

Going ahead to step 3:
872 can be fit into 396 0 times, resulting in a remainder of 396.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 396 to get 396.
Take the next digit (5) from the dividend and append it to 396, then repeat: 3965 / 872

Let's proceed to step 4:
When dividing 3965 by 872, we get 4 with a remainder of 477.
Write down 4 as next digit of the result. 
Result so far: 4.0
Deduct 3488 from 3965 and we're left with 477.
Bring next digit (7) of the dividend behind the 477 and repeat the process: 4777 / 872

Moving on to step 5:
872 goes into 4777 5 times with a remainder of 417.
Put 5 as the next digit of the answer. 
Result so far: 45.0
If we subtract 4360 from 4777, we get 417.
Bring next digit (4) of the dividend behind the 417 and repeat the process: 4174 / 872

Going ahead to step 6:
The number 872 fits into 4174 4 times, leaving a remainder of 686.
Record the quotient 4 as the next digit in the result. 
Result so far: 454.0
Subtracting 3488 from 4174 leaves us with 686.
Take the next digit (6) from the dividend and append it to 686, then repeat: 6866 / 872

On to step 7:
The number 872 fits into 6866 7 times, leaving a remainder of 762.
Use 7 as the next digit of our solution. 
Result so far: 4547.0
The remainder is 762 after subtracting 6104 from 6866.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7620, and continue the process.

Advancing to step 8:
872 can be fit into 7620 8 times, resulting in a remainder of 644.
Use 8 as the next digit of our solution. 
Result so far: 4547.8
Subtract 6976 from 7620 to get 644.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6440, and continue the process.

Let's proceed to step 9:
When dividing 6440 by 872, we get 7 with a remainder of 336.
Use 7 as the next digit of our solution. 
Result so far: 4547.87
Subtracting 6104 from 6440 leaves us with 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

Advancing to step 10:
872 can be fit into 3360 3 times, resulting in a remainder of 744.
Put 3 as the next digit of the answer. 
Result so far: 4547.873
If we take 2616 away from 3360, we end up with 744.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7440, and continue the process.

On to step 11:
872 goes into 7440 8 times with a remainder of 464.
Put 8 as the next digit of the answer. 
Result so far: 4547.8738
The remainder is 464 after subtracting 6976 from 7440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4640, and continue the process.

Let's proceed to step 12:
4640 divided by 872 is 5 with a remainder of 280.
The next digit of our result is 5. 
Result so far: 4547.87385
If we subtract 4360 from 4640, we get 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Step 13:
If we divide 2800 by 872, we get 3 and a remainder of 184.
Write down 3 as next digit of the result. 
Result so far: 4547.873853
Subtract 2616 from 2800 to get 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Let's proceed to step 14:
When dividing 1840 by 872, we get 2 with a remainder of 96.
Use 2 as the next digit of our solution. 
Result so far: 4547.8738532
If we subtract 1744 from 1840, we get 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

On to step 15:
The number 872 fits into 960 1 times, leaving a remainder of 88.
Put 1 as the next digit of the answer. 
Result so far: 4547.87385321
The remainder is 88 after subtracting 872 from 960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

The final result is 4547.87385321 with a remainder of 8.8e-08.
