We're dividing 742921 by 64 
We want to divide 742921 by 64.

On to step 1:
The number 64 fits into 7 0 times, leaving a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Grab the next digit (4) from the dividend, add it to 7, then carry on: 74 / 64

Moving on to step 2:
If we divide 74 by 64, we get 1 and a remainder of 10.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 10 after subtracting 64 from 74.
Include the next digit (2) from the dividend after 10, then repeat: 102 / 64

Moving on to step 3:
If we divide 102 by 64, we get 1 and a remainder of 38.
Use 1 as the next digit of our solution. 
Result so far: 11.0
If we take 64 away from 102, we end up with 38.
Include the next digit (9) from the dividend after 38, then repeat: 389 / 64

Step 4:
64 can be fit into 389 6 times, resulting in a remainder of 5.
The number 6 becomes the next digit in our result. 
Result so far: 116.0
Subtracting 384 from 389 leaves us with 5.
Append the next digit (2) from the dividend to 5 and continue with: 52 / 64

Going ahead to step 5:
The number 64 fits into 52 0 times, leaving a remainder of 52.
Use 0 as the next digit of our solution. 
Result so far: 1160.0
If we subtract 0 from 52, we get 52.
Bring next digit (1) of the dividend behind the 52 and repeat the process: 521 / 64

On to step 6:
When dividing 521 by 64, we get 8 with a remainder of 9.
Record the quotient 8 as the next digit in the result. 
Result so far: 11608.0
Subtract 512 from 521 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 7:
The number 64 fits into 90 1 times, leaving a remainder of 26.
Write down 1 as next digit of the result. 
Result so far: 11608.1
Subtract 64 from 90 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.

Let's proceed to step 8:
64 can be fit into 260 4 times, resulting in a remainder of 4.
Write down 4 as next digit of the result. 
Result so far: 11608.14
If we subtract 256 from 260, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 9:
64 goes into 40 0 times with a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 11608.14
If we take 0 away from 40, we end up 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.

Advancing to step 10:
The number 64 fits into 400 6 times, leaving a remainder of 16.
The next digit of our result is 6. 
Result so far: 11608.1406
The remainder is 16 after subtracting 384 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 11:
When dividing 160 by 64, we get 2 with a remainder of 32.
The next digit of our result is 2. 
Result so far: 11608.14062
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.

Step 12:
64 goes into 320 5 times with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 11608.140625
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 13:
0 divided by 64 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 11608.140625
Subtracting 0 from 0 leaves us 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.

Advancing to step 14:
When dividing 0 by 64, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 11608.140625
If we take 0 away from 0, we end up 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 11608.140625, with a leftover of 0.0.
