We look at the division of 4082942 by 980 
Let's see how many times 980 fits into 4082942.

Step 1:
The number 980 fits into 4 0 times, leaving a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Include the next digit (0) from the dividend after 4, then repeat: 40 / 980

Advancing to step 2:
If we divide 40 by 980, we get 0 and a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 40 to get 40.
Bring next digit (8) of the dividend behind the 40 and repeat the process: 408 / 980

Let's proceed to step 3:
If we divide 408 by 980, we get 0 and a remainder of 408.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 408 to get 408.
Bring next digit (2) of the dividend behind the 408 and repeat the process: 4082 / 980

Advancing to step 4:
If we divide 4082 by 980, we get 4 and a remainder of 162.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
If we take 3920 away from 4082, we end up with 162.
Bring next digit (9) of the dividend behind the 162 and repeat the process: 1629 / 980

Let's proceed to step 5:
980 can be fit into 1629 1 times, resulting in a remainder of 649.
Record the quotient 1 as the next digit in the result. 
Result so far: 41.0
Deduct 980 from 1629 and we're left with 649.
Grab the next digit (4) from the dividend, add it to 649, then carry on: 6494 / 980

Step 6:
The number 980 fits into 6494 6 times, leaving a remainder of 614.
Write down 6 as next digit of the result. 
Result so far: 416.0
Deduct 5880 from 6494 and we're left with 614.
Bring next digit (2) of the dividend behind the 614 and repeat the process: 6142 / 980

Advancing to step 7:
If we divide 6142 by 980, we get 6 and a remainder of 262.
The number 6 becomes the next digit in our result. 
Result so far: 4166.0
Subtract 5880 from 6142 to get 262.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2620, and continue the process.

Step 8:
2620 divided by 980 is 2 with a remainder of 660.
The number 2 becomes the next digit in our result. 
Result so far: 4166.2
If we take 1960 away from 2620, we end up with 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6600, and continue the process.

Let's proceed to step 9:
The number 980 fits into 6600 6 times, leaving a remainder of 720.
The next digit of our result is 6. 
Result so far: 4166.26
The remainder is 720 after subtracting 5880 from 6600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7200, and continue the process.

Let's proceed to step 10:
When dividing 7200 by 980, we get 7 with a remainder of 340.
The number 7 becomes the next digit in our result. 
Result so far: 4166.267
The remainder is 340 after subtracting 6860 from 7200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Step 11:
When dividing 3400 by 980, we get 3 with a remainder of 460.
The next digit of our result is 3. 
Result so far: 4166.2673
The remainder is 460 after subtracting 2940 from 3400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

Moving on to step 12:
The number 980 fits into 4600 4 times, leaving a remainder of 680.
The next digit of our result is 4. 
Result so far: 4166.26734
Subtract 3920 from 4600 to get 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6800, and continue the process.

Step 13:
6800 divided by 980 is 6 with a remainder of 920.
The number 6 becomes the next digit in our result. 
Result so far: 4166.267346
If we subtract 5880 from 6800, we get 920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9200, and continue the process.

Going ahead to step 14:
When dividing 9200 by 980, we get 9 with a remainder of 380.
The number 9 becomes the next digit in our result. 
Result so far: 4166.2673469
The remainder is 380 after subtracting 8820 from 9200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Step 15:
980 can be fit into 3800 3 times, resulting in a remainder of 860.
The next digit of our result is 3. 
Result so far: 4166.26734693
Deduct 2940 from 3800 and we're left with 860.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8600, and continue the process.

After the division, we end up with 4166.26734693 and a remainder of 8.6e-07.
