We divide 39657017 by 780
We want to figure out the number of times 39657017 can be divided by 780.

Step 1:
780 goes into 3 0 times with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 780

Moving on to step 2:
39 divided by 780 is 0 with a remainder of 39.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 39 leaves us with 39.
Include the next digit (6) from the dividend after 39, then repeat: 396 / 780

On to step 3:
396 divided by 780 is 0 with a remainder of 396.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 396 leaves us with 396.
Take the next digit (5) from the dividend and append it to 396, then repeat: 3965 / 780

Advancing to step 4:
If we divide 3965 by 780, we get 5 and a remainder of 65.
The next digit of our result is 5. 
Result so far: 5.0
If we subtract 3900 from 3965, we get 65.
Fetch the next digit (7) from the dividend, attach it to 65 and continue: 657 / 780

Moving on to step 5:
When dividing 657 by 780, we get 0 with a remainder of 657.
Record the quotient 0 as the next digit in the result. 
Result so far: 50.0
The remainder is 657 after subtracting 0 from 657.
Include the next digit (0) from the dividend after 657, then repeat: 6570 / 780

Step 6:
The number 780 fits into 6570 8 times, leaving a remainder of 330.
Use 8 as the next digit of our solution. 
Result so far: 508.0
Subtracting 6240 from 6570 leaves us with 330.
Grab the next digit (1) from the dividend, add it to 330, then carry on: 3301 / 780

Advancing to step 7:
780 can be fit into 3301 4 times, resulting in a remainder of 181.
The number 4 becomes the next digit in our result. 
Result so far: 5084.0
The remainder is 181 after subtracting 3120 from 3301.
Take the next digit (7) from the dividend and append it to 181, then repeat: 1817 / 780

On to step 8:
When dividing 1817 by 780, we get 2 with a remainder of 257.
The number 2 becomes the next digit in our result. 
Result so far: 50842.0
Deduct 1560 from 1817 and we're left with 257.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2570, and continue the process.

Let's proceed to step 9:
The number 780 fits into 2570 3 times, leaving a remainder of 230.
The next digit of our result is 3. 
Result so far: 50842.3
Deduct 2340 from 2570 and we're left with 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

On to step 10:
When dividing 2300 by 780, we get 2 with a remainder of 740.
The number 2 becomes the next digit in our result. 
Result so far: 50842.32
Subtracting 1560 from 2300 leaves us with 740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7400, and continue the process.

Step 11:
780 can be fit into 7400 9 times, resulting in a remainder of 380.
Record the quotient 9 as the next digit in the result. 
Result so far: 50842.329
Deduct 7020 from 7400 and we're left with 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

On to step 12:
When dividing 3800 by 780, we get 4 with a remainder of 680.
The number 4 becomes the next digit in our result. 
Result so far: 50842.3294
If we subtract 3120 from 3800, we 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.

On to step 13:
The number 780 fits into 6800 8 times, leaving a remainder of 560.
Use 8 as the next digit of our solution. 
Result so far: 50842.32948
The remainder is 560 after subtracting 6240 from 6800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Let's proceed to step 14:
When dividing 5600 by 780, we get 7 with a remainder of 140.
Use 7 as the next digit of our solution. 
Result so far: 50842.329487
The remainder is 140 after subtracting 5460 from 5600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

On to step 15:
780 goes into 1400 1 times with a remainder of 620.
Write down 1 as next digit of the result. 
Result so far: 50842.3294871
Subtracting 780 from 1400 leaves us with 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6200, and continue the process.

Moving on to step 16:
When dividing 6200 by 780, we get 7 with a remainder of 740.
Write down 7 as next digit of the result. 
Result so far: 50842.32948717
Subtracting 5460 from 6200 leaves us with 740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7400, and continue the process.

After the division, we end up with 50842.32948717 and a remainder of 7.4e-07.
