We look at the division of 16209845 by 77 
We want to divide 16209845 by 77.

Step 1:
The number 77 fits into 1 0 times, leaving a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Append the next digit (6) from the dividend to 1 and continue with: 16 / 77

Going ahead to step 2:
16 divided by 77 is 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 (2) of the dividend behind the 16 and repeat the process: 162 / 77

On to step 3:
77 can be fit into 162 2 times, resulting in a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we take 154 away from 162, we end up with 8.
Fetch the next digit (0) from the dividend, attach it to 8 and continue: 80 / 77

Moving on to step 4:
77 goes into 80 1 times with a remainder of 3.
The next digit of our result is 1. 
Result so far: 21.0
If we take 77 away from 80, we end up with 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 77

Moving on to step 5:
77 goes into 39 0 times with a remainder of 39.
The next digit of our result is 0. 
Result so far: 210.0
Subtract 0 from 39 to get 39.
Bring next digit (8) of the dividend behind the 39 and repeat the process: 398 / 77

Advancing to step 6:
If we divide 398 by 77, we get 5 and a remainder of 13.
Record the quotient 5 as the next digit in the result. 
Result so far: 2105.0
The remainder is 13 after subtracting 385 from 398.
Take the next digit (4) from the dividend and append it to 13, then repeat: 134 / 77

Advancing to step 7:
77 can be fit into 134 1 times, resulting in a remainder of 57.
Use 1 as the next digit of our solution. 
Result so far: 21051.0
Deduct 77 from 134 and we're left with 57.
Include the next digit (5) from the dividend after 57, then repeat: 575 / 77

Moving on to step 8:
If we divide 575 by 77, we get 7 and a remainder of 36.
The next digit of our result is 7. 
Result so far: 210517.0
Subtract 539 from 575 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 9:
If we divide 360 by 77, we get 4 and a remainder of 52.
Record the quotient 4 as the next digit in the result. 
Result so far: 210517.4
If we subtract 308 from 360, we get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Step 10:
If we divide 520 by 77, we get 6 and a remainder of 58.
The next digit of our result is 6. 
Result so far: 210517.46
Subtracting 462 from 520 leaves us with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Moving on to step 11:
77 can be fit into 580 7 times, resulting in a remainder of 41.
Record the quotient 7 as the next digit in the result. 
Result so far: 210517.467
The remainder is 41 after subtracting 539 from 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Advancing to step 12:
77 goes into 410 5 times with a remainder of 25.
The next digit of our result is 5. 
Result so far: 210517.4675
If we subtract 385 from 410, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Advancing to step 13:
The number 77 fits into 250 3 times, leaving a remainder of 19.
Use 3 as the next digit of our solution. 
Result so far: 210517.46753
If we subtract 231 from 250, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 14:
77 goes into 190 2 times with a remainder of 36.
Write down 2 as next digit of the result. 
Result so far: 210517.467532
The remainder is 36 after subtracting 154 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 15:
77 can be fit into 360 4 times, resulting in a remainder of 52.
The number 4 becomes the next digit in our result. 
Result so far: 210517.4675324
Subtract 308 from 360 to get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Advancing to step 16:
520 divided by 77 is 6 with a remainder of 58.
Use 6 as the next digit of our solution. 
Result so far: 210517.46753246
Subtracting 462 from 520 leaves us with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

The quotient of the division is 210517.46753246, and the remainder is 5.8e-08.
