We look at the division of 13977941 by 780 
We want to figure out the number of times 13977941 can be divided by 780.

Going ahead to step 1:
780 can be fit into 1 0 times, resulting in a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Bring next digit (3) of the dividend behind the 1 and repeat the process: 13 / 780

Advancing to step 2:
The number 780 fits into 13 0 times, leaving a remainder of 13.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 13 and we're left with 13.
Append the next digit (9) from the dividend to 13 and continue with: 139 / 780

Advancing to step 3:
When dividing 139 by 780, we get 0 with a remainder of 139.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 139 leaves us with 139.
Append the next digit (7) from the dividend to 139 and continue with: 1397 / 780

On to step 4:
780 goes into 1397 1 times with a remainder of 617.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 780 from 1397 leaves us with 617.
Include the next digit (7) from the dividend after 617, then repeat: 6177 / 780

Step 5:
780 goes into 6177 7 times with a remainder of 717.
Write down 7 as next digit of the result. 
Result so far: 17.0
Subtracting 5460 from 6177 leaves us with 717.
Grab the next digit (9) from the dividend, add it to 717, then carry on: 7179 / 780

Advancing to step 6:
When dividing 7179 by 780, we get 9 with a remainder of 159.
The number 9 becomes the next digit in our result. 
Result so far: 179.0
The remainder is 159 after subtracting 7020 from 7179.
Bring next digit (4) of the dividend behind the 159 and repeat the process: 1594 / 780

Step 7:
780 can be fit into 1594 2 times, resulting in a remainder of 34.
Use 2 as the next digit of our solution. 
Result so far: 1792.0
The remainder is 34 after subtracting 1560 from 1594.
Bring next digit (1) of the dividend behind the 34 and repeat the process: 341 / 780

Let's proceed to step 8:
If we divide 341 by 780, we get 0 and a remainder of 341.
The next digit of our result is 0. 
Result so far: 17920.0
If we subtract 0 from 341, we get 341.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3410, and continue the process.

Going ahead to step 9:
780 can be fit into 3410 4 times, resulting in a remainder of 290.
Record the quotient 4 as the next digit in the result. 
Result so far: 17920.4
Subtract 3120 from 3410 to get 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

Moving on to step 10:
780 goes into 2900 3 times with a remainder of 560.
Write down 3 as next digit of the result. 
Result so far: 17920.43
Subtracting 2340 from 2900 leaves us with 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Step 11:
If we divide 5600 by 780, we get 7 and a remainder of 140.
Use 7 as the next digit of our solution. 
Result so far: 17920.437
Deduct 5460 from 5600 and we're left with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Moving on to step 12:
780 can be fit into 1400 1 times, resulting in a remainder of 620.
The next digit of our result is 1. 
Result so far: 17920.4371
Subtract 780 from 1400 to get 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6200, and continue the process.

Step 13:
6200 divided by 780 is 7 with a remainder of 740.
Put 7 as the next digit of the answer. 
Result so far: 17920.43717
Subtract 5460 from 6200 to get 740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7400, and continue the process.

Let's proceed to step 14:
780 can be fit into 7400 9 times, resulting in a remainder of 380.
Write down 9 as next digit of the result. 
Result so far: 17920.437179
The remainder is 380 after subtracting 7020 from 7400.
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 15:
The number 780 fits into 3800 4 times, leaving a remainder of 680.
Write down 4 as next digit of the result. 
Result so far: 17920.4371794
Subtracting 3120 from 3800 leaves us with 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 16:
If we divide 6800 by 780, we get 8 and a remainder of 560.
Record the quotient 8 as the next digit in the result. 
Result so far: 17920.43717948
Subtracting 6240 from 6800 leaves us with 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

After the division, we end up with 17920.43717948 and a remainder of 5.6e-07.
