We look at the division of 77504561 by 216 
We want to divide 77504561 by 216.

Let's proceed to step 1:
If we divide 7 by 216, we get 0 and a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Fetch the next digit (7) from the dividend, attach it to 7 and continue: 77 / 216

On to step 2:
When dividing 77 by 216, we get 0 with a remainder of 77.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 77 leaves us with 77.
Append the next digit (5) from the dividend to 77 and continue with: 775 / 216

Going ahead to step 3:
216 can be fit into 775 3 times, resulting in a remainder of 127.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtracting 648 from 775 leaves us with 127.
Grab the next digit (0) from the dividend, add it to 127, then carry on: 1270 / 216

Step 4:
216 can be fit into 1270 5 times, resulting in a remainder of 190.
Write down 5 as next digit of the result. 
Result so far: 35.0
If we take 1080 away from 1270, we end up with 190.
Take the next digit (4) from the dividend and append it to 190, then repeat: 1904 / 216

Moving on to step 5:
216 can be fit into 1904 8 times, resulting in a remainder of 176.
Put 8 as the next digit of the answer. 
Result so far: 358.0
If we take 1728 away from 1904, we end up with 176.
Take the next digit (5) from the dividend and append it to 176, then repeat: 1765 / 216

Let's proceed to step 6:
1765 divided by 216 is 8 with a remainder of 37.
Put 8 as the next digit of the answer. 
Result so far: 3588.0
Subtracting 1728 from 1765 leaves us with 37.
Append the next digit (6) from the dividend to 37 and continue with: 376 / 216

Advancing to step 7:
216 goes into 376 1 times with a remainder of 160.
The next digit of our result is 1. 
Result so far: 35881.0
The remainder is 160 after subtracting 216 from 376.
Take the next digit (1) from the dividend and append it to 160, then repeat: 1601 / 216

Moving on to step 8:
216 goes into 1601 7 times with a remainder of 89.
Put 7 as the next digit of the answer. 
Result so far: 358817.0
The remainder is 89 after subtracting 1512 from 1601.
Since there are no more digits in the dividend, we add a zero to the remainder making it 890, and continue the process.

Let's proceed to step 9:
If we divide 890 by 216, we get 4 and a remainder of 26.
Put 4 as the next digit of the answer. 
Result so far: 358817.4
If we take 864 away from 890, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Let's proceed to step 10:
The number 216 fits into 260 1 times, leaving a remainder of 44.
The number 1 becomes the next digit in our result. 
Result so far: 358817.41
Subtracting 216 from 260 leaves us with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Advancing to step 11:
If we divide 440 by 216, we get 2 and a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 358817.412
If we subtract 432 from 440, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 12:
216 can be fit into 80 0 times, resulting in a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 358817.412
Deduct 0 from 80 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Moving on to step 13:
216 goes into 800 3 times with a remainder of 152.
Write down 3 as next digit of the result. 
Result so far: 358817.41203
Subtracting 648 from 800 leaves us with 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

On to step 14:
The number 216 fits into 1520 7 times, leaving a remainder of 8.
The next digit of our result is 7. 
Result so far: 358817.412037
The remainder is 8 after subtracting 1512 from 1520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 15:
80 divided by 216 is 0 with a remainder of 80.
Record the quotient 0 as the next digit in the result. 
Result so far: 358817.412037
Subtracting 0 from 80 leaves us with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Going ahead to step 16:
If we divide 800 by 216, we get 3 and a remainder of 152.
Put 3 as the next digit of the answer. 
Result so far: 358817.41203703
Subtract 648 from 800 to get 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

The final outcome is 358817.41203703, with a leftover of 1.52e-07.
