3962959 ÷ 876 
The aim is to understand the frequency of 876 in 3962959.

On to step 1:
876 can be fit into 3 0 times, resulting in a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 876

Let's proceed to step 2:
876 can be fit into 39 0 times, resulting in a remainder of 39.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 39 leaves us with 39.
Include the next digit (6) from the dividend after 39, then repeat: 396 / 876

Moving on to step 3:
876 can be fit into 396 0 times, resulting in a remainder of 396.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 396, we end up with 396.
Bring next digit (2) of the dividend behind the 396 and repeat the process: 3962 / 876

Going ahead to step 4:
876 can be fit into 3962 4 times, resulting in a remainder of 458.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtract 3504 from 3962 to get 458.
Fetch the next digit (9) from the dividend, attach it to 458 and continue: 4589 / 876

Step 5:
The number 876 fits into 4589 5 times, leaving a remainder of 209.
Use 5 as the next digit of our solution. 
Result so far: 45.0
Deduct 4380 from 4589 and we're left with 209.
Grab the next digit (5) from the dividend, add it to 209, then carry on: 2095 / 876

Moving on to step 6:
876 goes into 2095 2 times with a remainder of 343.
Put 2 as the next digit of the answer. 
Result so far: 452.0
The remainder is 343 after subtracting 1752 from 2095.
Bring next digit (9) of the dividend behind the 343 and repeat the process: 3439 / 876

Going ahead to step 7:
876 can be fit into 3439 3 times, resulting in a remainder of 811.
Record the quotient 3 as the next digit in the result. 
Result so far: 4523.0
The remainder is 811 after subtracting 2628 from 3439.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8110, and continue the process.

Advancing to step 8:
8110 divided by 876 is 9 with a remainder of 226.
Put 9 as the next digit of the answer. 
Result so far: 4523.9
Subtract 7884 from 8110 to get 226.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2260, and continue the process.

Moving on to step 9:
The number 876 fits into 2260 2 times, leaving a remainder of 508.
Record the quotient 2 as the next digit in the result. 
Result so far: 4523.92
Subtracting 1752 from 2260 leaves us with 508.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5080, and continue the process.

Let's proceed to step 10:
If we divide 5080 by 876, we get 5 and a remainder of 700.
Put 5 as the next digit of the answer. 
Result so far: 4523.925
Deduct 4380 from 5080 and we're left with 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7000, and continue the process.

Step 11:
876 can be fit into 7000 7 times, resulting in a remainder of 868.
The number 7 becomes the next digit in our result. 
Result so far: 4523.9257
The remainder is 868 after subtracting 6132 from 7000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8680, and continue the process.

Moving on to step 12:
876 goes into 8680 9 times with a remainder of 796.
The number 9 becomes the next digit in our result. 
Result so far: 4523.92579
Deduct 7884 from 8680 and we're left with 796.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7960, and continue the process.

Advancing to step 13:
The number 876 fits into 7960 9 times, leaving a remainder of 76.
The number 9 becomes the next digit in our result. 
Result so far: 4523.925799
The remainder is 76 after subtracting 7884 from 7960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Our division results in 4523.925799 with a remaining 7.6e-06.
