39907069 ÷ 980 
We're looking to find how many times 980 goes into 39907069.

Going ahead to step 1:
980 can be fit into 3 0 times, resulting in a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Bring next digit (9) of the dividend behind the 3 and repeat the process: 39 / 980

Step 2:
980 goes into 39 0 times with a remainder of 39.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 39, we get 39.
Grab the next digit (9) from the dividend, add it to 39, then carry on: 399 / 980

On to step 3:
399 divided by 980 is 0 with a remainder of 399.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 399 leaves us with 399.
Take the next digit (0) from the dividend and append it to 399, then repeat: 3990 / 980

Advancing to step 4:
3990 divided by 980 is 4 with a remainder of 70.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we subtract 3920 from 3990, we get 70.
Include the next digit (7) from the dividend after 70, then repeat: 707 / 980

Moving on to step 5:
980 can be fit into 707 0 times, resulting in a remainder of 707.
The next digit of our result is 0. 
Result so far: 40.0
Subtracting 0 from 707 leaves us with 707.
Append the next digit (0) from the dividend to 707 and continue with: 7070 / 980

Moving on to step 6:
If we divide 7070 by 980, we get 7 and a remainder of 210.
The next digit of our result is 7. 
Result so far: 407.0
Subtract 6860 from 7070 to get 210.
Fetch the next digit (6) from the dividend, attach it to 210 and continue: 2106 / 980

Going ahead to step 7:
The number 980 fits into 2106 2 times, leaving a remainder of 146.
The next digit of our result is 2. 
Result so far: 4072.0
If we take 1960 away from 2106, we end up with 146.
Take the next digit (9) from the dividend and append it to 146, then repeat: 1469 / 980

Advancing to step 8:
The number 980 fits into 1469 1 times, leaving a remainder of 489.
The number 1 becomes the next digit in our result. 
Result so far: 40721.0
Subtract 980 from 1469 to get 489.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4890, and continue the process.

Moving on to step 9:
980 goes into 4890 4 times with a remainder of 970.
Use 4 as the next digit of our solution. 
Result so far: 40721.4
Deduct 3920 from 4890 and we're left with 970.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9700, and continue the process.

On to step 10:
980 can be fit into 9700 9 times, resulting in a remainder of 880.
Put 9 as the next digit of the answer. 
Result so far: 40721.49
Subtract 8820 from 9700 to get 880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8800, and continue the process.

Step 11:
If we divide 8800 by 980, we get 8 and a remainder of 960.
The number 8 becomes the next digit in our result. 
Result so far: 40721.498
If we take 7840 away from 8800, we end up with 960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9600, and continue the process.

Step 12:
If we divide 9600 by 980, we get 9 and a remainder of 780.
Use 9 as the next digit of our solution. 
Result so far: 40721.4989
Subtracting 8820 from 9600 leaves us with 780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7800, and continue the process.

Moving on to step 13:
7800 divided by 980 is 7 with a remainder of 940.
The number 7 becomes the next digit in our result. 
Result so far: 40721.49897
If we take 6860 away from 7800, we end up with 940.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9400, and continue the process.

Advancing to step 14:
9400 divided by 980 is 9 with a remainder of 580.
Put 9 as the next digit of the answer. 
Result so far: 40721.498979
If we subtract 8820 from 9400, 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.

On to step 15:
The number 980 fits into 5800 5 times, leaving a remainder of 900.
Put 5 as the next digit of the answer. 
Result so far: 40721.4989795
The remainder is 900 after subtracting 4900 from 5800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9000, and continue the process.

Let's proceed to step 16:
When dividing 9000 by 980, we get 9 with a remainder of 180.
The number 9 becomes the next digit in our result. 
Result so far: 40721.49897959
Subtracting 8820 from 9000 leaves us with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

In conclusion, the division gives 40721.49897959 with a balance of 1.8e-07.
