16400537 divided by 781 
We're looking to find how many times 781 goes into 16400537.

Moving on to step 1:
When dividing 1 by 781, we get 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Append the next digit (6) from the dividend to 1 and continue with: 16 / 781

Going ahead to step 2:
When dividing 16 by 781, we get 0 with a remainder of 16.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 16 after subtracting 0 from 16.
Bring next digit (4) of the dividend behind the 16 and repeat the process: 164 / 781

Step 3:
The number 781 fits into 164 0 times, leaving a remainder of 164.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 164 leaves us with 164.
Fetch the next digit (0) from the dividend, attach it to 164 and continue: 1640 / 781

Advancing to step 4:
1640 divided by 781 is 2 with a remainder of 78.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we subtract 1562 from 1640, we get 78.
Bring next digit (0) of the dividend behind the 78 and repeat the process: 780 / 781

Step 5:
The number 781 fits into 780 0 times, leaving a remainder of 780.
Write down 0 as next digit of the result. 
Result so far: 20.0
If we take 0 away from 780, we end up with 780.
Bring next digit (5) of the dividend behind the 780 and repeat the process: 7805 / 781

Advancing to step 6:
781 can be fit into 7805 9 times, resulting in a remainder of 776.
Record the quotient 9 as the next digit in the result. 
Result so far: 209.0
If we subtract 7029 from 7805, we get 776.
Include the next digit (3) from the dividend after 776, then repeat: 7763 / 781

Advancing to step 7:
When dividing 7763 by 781, we get 9 with a remainder of 734.
Use 9 as the next digit of our solution. 
Result so far: 2099.0
Subtract 7029 from 7763 to get 734.
Take the next digit (7) from the dividend and append it to 734, then repeat: 7347 / 781

Going ahead to step 8:
If we divide 7347 by 781, we get 9 and a remainder of 318.
The next digit of our result is 9. 
Result so far: 20999.0
Deduct 7029 from 7347 and we're left with 318.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3180, and continue the process.

Advancing to step 9:
If we divide 3180 by 781, we get 4 and a remainder of 56.
Put 4 as the next digit of the answer. 
Result so far: 20999.4
If we subtract 3124 from 3180, we get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Let's proceed to step 10:
When dividing 560 by 781, we get 0 with a remainder of 560.
Use 0 as the next digit of our solution. 
Result so far: 20999.4
If we take 0 away from 560, we end up 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.

Advancing to step 11:
If we divide 5600 by 781, we get 7 and a remainder of 133.
Write down 7 as next digit of the result. 
Result so far: 20999.407
The remainder is 133 after subtracting 5467 from 5600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1330, and continue the process.

Going ahead to step 12:
1330 divided by 781 is 1 with a remainder of 549.
The number 1 becomes the next digit in our result. 
Result so far: 20999.4071
Deduct 781 from 1330 and we're left with 549.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5490, and continue the process.

Step 13:
5490 divided by 781 is 7 with a remainder of 23.
Write down 7 as next digit of the result. 
Result so far: 20999.40717
If we take 5467 away from 5490, we end up with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Step 14:
781 can be fit into 230 0 times, resulting in a remainder of 230.
Put 0 as the next digit of the answer. 
Result so far: 20999.40717
Subtracting 0 from 230 leaves us 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 15:
781 goes into 2300 2 times with a remainder of 738.
Use 2 as the next digit of our solution. 
Result so far: 20999.4071702
Subtracting 1562 from 2300 leaves us with 738.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7380, and continue the process.

Step 16:
781 goes into 7380 9 times with a remainder of 351.
Record the quotient 9 as the next digit in the result. 
Result so far: 20999.40717029
Deduct 7029 from 7380 and we're left with 351.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3510, and continue the process.

In conclusion, the division gives 20999.40717029 with a balance of 3.51e-07.
