If we divide 2037 by 980, we get 2 and a remainder of 77.
Use 2 as the next digit of our solution. 
Result so far: 82.0
Deduct 1960 from 2037 and we're left with 77.
Append the next digit (6) from the dividend to 77 and continue with: 776 / 980

Step 6:
If we divide 776 by 980, we get 0 and a remainder of 776.
The number 0 becomes the next digit in our result. 
Result so far: 820.0
If we take 0 away from 776, we end up with 776.
Fetch the next digit (6) from the dividend, attach it to 776 and continue: 7766 / 980

Going ahead to step 7:
980 goes into 7766 7 times with a remainder of 906.
The number 7 becomes the next digit in our result. 
Result so far: 8207.0
Subtract 6860 from 7766 to get 906.
Fetch the next digit (1) from the dividend, attach it to 906 and continue: 9061 / 980

Going ahead to step 8:
The number 980 fits into 9061 9 times, leaving a remainder of 241.
The number 9 becomes the next digit in our result. 
Result so far: 82079.0
Subtract 8820 from 9061 to get 241.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2410, and continue the process.

Going ahead to step 9:
980 goes into 2410 2 times with a remainder of 450.
Use 2 as the next digit of our solution. 
Result so far: 82079.2
Subtract 1960 from 2410 to get 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

Going ahead to step 10:
980 goes into 4500 4 times with a remainder of 580.
The next digit of our result is 4. 
Result so far: 82079.24
Subtract 3920 from 4500 to get 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5800, and continue the process.

Let's proceed to step 11:
If we divide 5800 by 980, we get 5 and a remainder of 900.
Use 5 as the next digit of our solution. 
Result so far: 82079.245
Deduct 4900 from 5800 and we're left with 900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9000, and continue the process.

Advancing to step 12:
The number 980 fits into 9000 9 times, leaving a remainder of 180.
Use 9 as the next digit of our solution. 
Result so far: 82079.2459
The remainder is 180 after subtracting 8820 from 9000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Going ahead to step 13:
When dividing 1800 by 980, we get 1 with a remainder of 820.
Put 1 as the next digit of the answer. 
Result so far: 82079.24591
If we subtract 980 from 1800, we get 820.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8200, and continue the process.

Going ahead to step 14:
The number 980 fits into 8200 8 times, leaving a remainder of 360.
Use 8 as the next digit of our solution. 
Result so far: 82079.245918
If we take 7840 away from 8200, we end up with 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Going ahead to step 15:
980 goes into 3600 3 times with a remainder of 660.
Put 3 as the next digit of the answer. 
Result so far: 82079.2459183
If we subtract 2940 from 3600, we get 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6600, and continue the process.

Advancing to step 16:
When dividing 6600 by 980, we get 6 with a remainder of 720.
The number 6 becomes the next digit in our result. 
Result so far: 82079.24591836
If we take 5880 away from 6600, we end up with 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7200, and continue the process.

The quotient of the division is 82079.24591836, and the remainder is 7.2e-07.
