3645645 divided by 980 
We want to figure out the number of times 3645645 can be divided by 980.

On to step 1:
The number 980 fits into 3 0 times, leaving a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Grab the next digit (6) from the dividend, add it to 3, then carry on: 36 / 980

Going ahead to step 2:
980 goes into 36 0 times with a remainder of 36.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 36 leaves us with 36.
Append the next digit (4) from the dividend to 36 and continue with: 364 / 980

Let's proceed to step 3:
If we divide 364 by 980, we get 0 and a remainder of 364.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 364, we end up with 364.
Append the next digit (5) from the dividend to 364 and continue with: 3645 / 980

Step 4:
3645 divided by 980 is 3 with a remainder of 705.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtract 2940 from 3645 to get 705.
Bring next digit (6) of the dividend behind the 705 and repeat the process: 7056 / 980

Advancing to step 5:
980 can be fit into 7056 7 times, resulting in a remainder of 196.
The number 7 becomes the next digit in our result. 
Result so far: 37.0
The remainder is 196 after subtracting 6860 from 7056.
Include the next digit (4) from the dividend after 196, then repeat: 1964 / 980

Let's proceed to step 6:
980 can be fit into 1964 2 times, resulting in a remainder of 4.
The number 2 becomes the next digit in our result. 
Result so far: 372.0
If we take 1960 away from 1964, we end up with 4.
Append the next digit (5) from the dividend to 4 and continue with: 45 / 980

Step 7:
45 divided by 980 is 0 with a remainder of 45.
Record the quotient 0 as the next digit in the result. 
Result so far: 3720.0
If we subtract 0 from 45, we get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Let's proceed to step 8:
450 divided by 980 is 0 with a remainder of 450.
Write down 0 as next digit of the result. 
Result so far: 3720.0
Subtract 0 from 450 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.

Advancing to step 9:
If we divide 4500 by 980, we get 4 and a remainder of 580.
The number 4 becomes the next digit in our result. 
Result so far: 3720.04
If we subtract 3920 from 4500, we 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.

Advancing to step 10:
The number 980 fits into 5800 5 times, leaving a remainder of 900.
The next digit of our result is 5. 
Result so far: 3720.045
If we take 4900 away from 5800, we end up 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 11:
980 goes into 9000 9 times with a remainder of 180.
The next digit of our result is 9. 
Result so far: 3720.0459
Subtract 8820 from 9000 to get 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Advancing to step 12:
980 goes into 1800 1 times with a remainder of 820.
Use 1 as the next digit of our solution. 
Result so far: 3720.04591
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.

Moving on to step 13:
980 goes into 8200 8 times with a remainder of 360.
Put 8 as the next digit of the answer. 
Result so far: 3720.045918
The remainder is 360 after subtracting 7840 from 8200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Advancing to step 14:
980 can be fit into 3600 3 times, resulting in a remainder of 660.
Record the quotient 3 as the next digit in the result. 
Result so far: 3720.0459183
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.

On to step 15:
The number 980 fits into 6600 6 times, leaving a remainder of 720.
Write down 6 as next digit of the result. 
Result so far: 3720.04591836
If we subtract 5880 from 6600, we get 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 3720.04591836, and the remainder is 7.2e-07.
