16437004 ÷ 771 
We want to divide 16437004 by 771.

Going ahead to step 1:
1 divided by 771 is 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Fetch the next digit (6) from the dividend, attach it to 1 and continue: 16 / 771

Going ahead to step 2:
The number 771 fits into 16 0 times, leaving a remainder of 16.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 16, we end up with 16.
Bring next digit (4) of the dividend behind the 16 and repeat the process: 164 / 771

Let's proceed to step 3:
771 goes into 164 0 times with a remainder of 164.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 164, we end up with 164.
Append the next digit (3) from the dividend to 164 and continue with: 1643 / 771

Advancing to step 4:
If we divide 1643 by 771, we get 2 and a remainder of 101.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtracting 1542 from 1643 leaves us with 101.
Bring next digit (7) of the dividend behind the 101 and repeat the process: 1017 / 771

Step 5:
If we divide 1017 by 771, we get 1 and a remainder of 246.
Write down 1 as next digit of the result. 
Result so far: 21.0
If we take 771 away from 1017, we end up with 246.
Take the next digit (0) from the dividend and append it to 246, then repeat: 2460 / 771

Advancing to step 6:
771 goes into 2460 3 times with a remainder of 147.
Use 3 as the next digit of our solution. 
Result so far: 213.0
If we subtract 2313 from 2460, we get 147.
Bring next digit (0) of the dividend behind the 147 and repeat the process: 1470 / 771

Advancing to step 7:
The number 771 fits into 1470 1 times, leaving a remainder of 699.
Record the quotient 1 as the next digit in the result. 
Result so far: 2131.0
If we subtract 771 from 1470, we get 699.
Append the next digit (4) from the dividend to 699 and continue with: 6994 / 771

Going ahead to step 8:
771 can be fit into 6994 9 times, resulting in a remainder of 55.
The next digit of our result is 9. 
Result so far: 21319.0
If we take 6939 away from 6994, we end up with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Going ahead to step 9:
771 can be fit into 550 0 times, resulting in a remainder of 550.
The next digit of our result is 0. 
Result so far: 21319.0
Deduct 0 from 550 and we're left with 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5500, and continue the process.

On to step 10:
If we divide 5500 by 771, we get 7 and a remainder of 103.
The next digit of our result is 7. 
Result so far: 21319.07
Deduct 5397 from 5500 and we're left with 103.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1030, and continue the process.

Moving on to step 11:
The number 771 fits into 1030 1 times, leaving a remainder of 259.
The number 1 becomes the next digit in our result. 
Result so far: 21319.071
The remainder is 259 after subtracting 771 from 1030.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2590, and continue the process.

Let's proceed to step 12:
2590 divided by 771 is 3 with a remainder of 277.
The next digit of our result is 3. 
Result so far: 21319.0713
The remainder is 277 after subtracting 2313 from 2590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2770, and continue the process.

Advancing to step 13:
When dividing 2770 by 771, we get 3 with a remainder of 457.
The next digit of our result is 3. 
Result so far: 21319.07133
If we take 2313 away from 2770, we end up with 457.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4570, and continue the process.

The final outcome is 21319.07133, with a leftover of 0.000457.
