73407 ÷ 64 
We're looking to find how many times 64 goes into 73407.

Advancing to step 1:
The number 64 fits into 7 0 times, leaving 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.
Append the next digit (3) from the dividend to 7 and continue with: 73 / 64

Advancing to step 2:
When dividing 73 by 64, we get 1 with a remainder of 9.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 64 away from 73, we end up with 9.
Take the next digit (4) from the dividend and append it to 9, then repeat: 94 / 64

Moving on to step 3:
64 can be fit into 94 1 times, resulting in a remainder of 30.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
The remainder is 30 after subtracting 64 from 94.
Fetch the next digit (0) from the dividend, attach it to 30 and continue: 300 / 64

Advancing to step 4:
If we divide 300 by 64, we get 4 and a remainder of 44.
Put 4 as the next digit of the answer. 
Result so far: 114.0
If we take 256 away from 300, we end up with 44.
Bring next digit (7) of the dividend behind the 44 and repeat the process: 447 / 64

Advancing to step 5:
447 divided by 64 is 6 with a remainder of 63.
The next digit of our result is 6. 
Result so far: 1146.0
If we take 384 away from 447, we end up with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Going ahead to step 6:
The number 64 fits into 630 9 times, leaving a remainder of 54.
Use 9 as the next digit of our solution. 
Result so far: 1146.9
Subtracting 576 from 630 leaves us with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Step 7:
540 divided by 64 is 8 with a remainder of 28.
Write down 8 as next digit of the result. 
Result so far: 1146.98
If we subtract 512 from 540, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 8:
64 goes into 280 4 times with a remainder of 24.
Put 4 as the next digit of the answer. 
Result so far: 1146.984
If we subtract 256 from 280, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 9:
The number 64 fits into 240 3 times, leaving a remainder of 48.
Put 3 as the next digit of the answer. 
Result so far: 1146.9843
If we subtract 192 from 240, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Moving on to step 10:
64 can be fit into 480 7 times, resulting in a remainder of 32.
Use 7 as the next digit of our solution. 
Result so far: 1146.98437
Subtracting 448 from 480 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 11:
64 can be fit into 320 5 times, resulting in a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 1146.984375
If we subtract 320 from 320, 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.

Let's proceed to step 12:
64 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 1146.984375
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.

Step 13:
If we divide 0 by 64, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 1146.984375
Deduct 0 from 0 and we're left with 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 outcome is 1146.984375, with a leftover of 0.0.
