The number 976 fits into 2156 2 times, leaving a remainder of 204.
The next digit of our result is 2. 
Result so far: 2.0
Deduct 1952 from 2156 and we're left with 204.
Take the next digit (6) from the dividend and append it to 204, then repeat: 2046 / 976

Advancing to step 5:
976 goes into 2046 2 times with a remainder of 94.
The next digit of our result is 2. 
Result so far: 22.0
Subtract 1952 from 2046 to get 94.
Append the next digit (6) from the dividend to 94 and continue with: 946 / 976

On to step 6:
976 can be fit into 946 0 times, resulting in a remainder of 946.
Put 0 as the next digit of the answer. 
Result so far: 220.0
Subtracting 0 from 946 leaves us with 946.
Take the next digit (3) from the dividend and append it to 946, then repeat: 9463 / 976

Let's proceed to step 7:
When dividing 9463 by 976, we get 9 with a remainder of 679.
Write down 9 as next digit of the result. 
Result so far: 2209.0
If we take 8784 away from 9463, we end up with 679.
Append the next digit (7) from the dividend to 679 and continue with: 6797 / 976

On to step 8:
The number 976 fits into 6797 6 times, leaving a remainder of 941.
The next digit of our result is 6. 
Result so far: 22096.0
Subtract 5856 from 6797 to get 941.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9410, and continue the process.

On to step 9:
976 can be fit into 9410 9 times, resulting in a remainder of 626.
The next digit of our result is 9. 
Result so far: 22096.9
Subtracting 8784 from 9410 leaves us with 626.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6260, and continue the process.

Step 10:
The number 976 fits into 6260 6 times, leaving a remainder of 404.
The next digit of our result is 6. 
Result so far: 22096.96
Deduct 5856 from 6260 and we're left with 404.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4040, and continue the process.

Step 11:
The number 976 fits into 4040 4 times, leaving a remainder of 136.
Record the quotient 4 as the next digit in the result. 
Result so far: 22096.964
The remainder is 136 after subtracting 3904 from 4040.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Moving on to step 12:
When dividing 1360 by 976, we get 1 with a remainder of 384.
Record the quotient 1 as the next digit in the result. 
Result so far: 22096.9641
Subtracting 976 from 1360 leaves us with 384.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

Going ahead to step 13:
976 can be fit into 3840 3 times, resulting in a remainder of 912.
The next digit of our result is 3. 
Result so far: 22096.96413
Subtracting 2928 from 3840 leaves us with 912.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9120, and continue the process.

Let's proceed to step 14:
9120 divided by 976 is 9 with a remainder of 336.
The number 9 becomes the next digit in our result. 
Result so far: 22096.964139
Subtracting 8784 from 9120 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.

Let's proceed to step 15:
If we divide 3360 by 976, we get 3 and a remainder of 432.
The number 3 becomes the next digit in our result. 
Result so far: 22096.9641393
If we take 2928 away from 3360, we end up with 432.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4320, and continue the process.

Moving on to step 16:
The number 976 fits into 4320 4 times, leaving a remainder of 416.
The next digit of our result is 4. 
Result so far: 22096.96413934
If we subtract 3904 from 4320, we get 416.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

Our division results in 22096.96413934 with a remaining 4.16e-07.
