Let's divide 73983209 by 64
We're looking to find how many times 64 goes into 73983209.

Moving on to step 1:
64 goes into 7 0 times with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Grab the next digit (3) from the dividend, add it to 7, then carry on: 73 / 64

Let's proceed to step 2:
When dividing 73 by 64, we get 1 with a remainder of 9.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 64 from 73 and we're left with 9.
Include the next digit (9) from the dividend after 9, then repeat: 99 / 64

Let's proceed to step 3:
64 goes into 99 1 times with a remainder of 35.
Put 1 as the next digit of the answer. 
Result so far: 11.0
If we subtract 64 from 99, we get 35.
Include the next digit (8) from the dividend after 35, then repeat: 358 / 64

Step 4:
64 goes into 358 5 times with a remainder of 38.
Use 5 as the next digit of our solution. 
Result so far: 115.0
The remainder is 38 after subtracting 320 from 358.
Grab the next digit (3) from the dividend, add it to 38, then carry on: 383 / 64

Step 5:
The number 64 fits into 383 5 times, leaving a remainder of 63.
The next digit of our result is 5. 
Result so far: 1155.0
The remainder is 63 after subtracting 320 from 383.
Append the next digit (2) from the dividend to 63 and continue with: 632 / 64

Let's proceed to step 6:
64 goes into 632 9 times with a remainder of 56.
Use 9 as the next digit of our solution. 
Result so far: 11559.0
Deduct 576 from 632 and we're left with 56.
Include the next digit (0) from the dividend after 56, then repeat: 560 / 64

Advancing to step 7:
64 goes into 560 8 times with a remainder of 48.
The number 8 becomes the next digit in our result. 
Result so far: 115598.0
If we subtract 512 from 560, we get 48.
Grab the next digit (9) from the dividend, add it to 48, then carry on: 489 / 64

On to step 8:
489 divided by 64 is 7 with a remainder of 41.
The number 7 becomes the next digit in our result. 
Result so far: 1155987.0
If we take 448 away from 489, we end up with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Going ahead to step 9:
64 can be fit into 410 6 times, resulting in a remainder of 26.
Put 6 as the next digit of the answer. 
Result so far: 1155987.6
Subtract 384 from 410 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Advancing to step 10:
When dividing 260 by 64, we get 4 with a remainder of 4.
Put 4 as the next digit of the answer. 
Result so far: 1155987.64
If we take 256 away from 260, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 11:
64 goes into 40 0 times with a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 1155987.64
Deduct 0 from 40 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 12:
64 goes into 400 6 times with a remainder of 16.
The next digit of our result is 6. 
Result so far: 1155987.6406
Deduct 384 from 400 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 13:
The number 64 fits into 160 2 times, leaving a remainder of 32.
Write down 2 as next digit of the result. 
Result so far: 1155987.64062
Subtract 128 from 160 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 14:
When dividing 320 by 64, we get 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 1155987.640625
Subtract 320 from 320 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 15:
When dividing 0 by 64, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 1155987.640625
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 16:
64 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 1155987.640625
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 1155987.640625 with a remainder of 0.0.
