We're dividing 7147903 by 64 
Our goal is to divide 7147903 by 64.

Let's proceed to step 1:
If we divide 7 by 64, we get 0 and a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Bring next digit (1) of the dividend behind the 7 and repeat the process: 71 / 64

Moving on to step 2:
When dividing 71 by 64, we get 1 with a remainder of 7.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 64 from 71 to get 7.
Fetch the next digit (4) from the dividend, attach it to 7 and continue: 74 / 64

Going ahead to step 3:
74 divided by 64 is 1 with a remainder of 10.
Put 1 as the next digit of the answer. 
Result so far: 11.0
The remainder is 10 after subtracting 64 from 74.
Append the next digit (7) from the dividend to 10 and continue with: 107 / 64

Let's proceed to step 4:
107 divided by 64 is 1 with a remainder of 43.
Record the quotient 1 as the next digit in the result. 
Result so far: 111.0
Deduct 64 from 107 and we're left with 43.
Fetch the next digit (9) from the dividend, attach it to 43 and continue: 439 / 64

Advancing to step 5:
64 goes into 439 6 times with a remainder of 55.
The next digit of our result is 6. 
Result so far: 1116.0
Subtract 384 from 439 to get 55.
Bring next digit (0) of the dividend behind the 55 and repeat the process: 550 / 64

Going ahead to step 6:
If we divide 550 by 64, we get 8 and a remainder of 38.
The number 8 becomes the next digit in our result. 
Result so far: 11168.0
Deduct 512 from 550 and we're left with 38.
Append the next digit (3) from the dividend to 38 and continue with: 383 / 64

On to step 7:
383 divided by 64 is 5 with a remainder of 63.
Write down 5 as next digit of the result. 
Result so far: 111685.0
Subtract 320 from 383 to get 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Let's proceed to step 8:
The number 64 fits into 630 9 times, leaving a remainder of 54.
Put 9 as the next digit of the answer. 
Result so far: 111685.9
If we subtract 576 from 630, we get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Moving on to step 9:
The number 64 fits into 540 8 times, leaving a remainder of 28.
The next digit of our result is 8. 
Result so far: 111685.98
If we take 512 away from 540, we end up with 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 10:
64 can be fit into 280 4 times, resulting in a remainder of 24.
Put 4 as the next digit of the answer. 
Result so far: 111685.984
If we take 256 away from 280, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 11:
64 can be fit into 240 3 times, resulting in a remainder of 48.
Use 3 as the next digit of our solution. 
Result so far: 111685.9843
Subtract 192 from 240 to 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 12:
If we divide 480 by 64, we get 7 and a remainder of 32.
Write down 7 as next digit of the result. 
Result so far: 111685.98437
Subtract 448 from 480 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 13:
The number 64 fits into 320 5 times, leaving a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 111685.984375
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.

On to step 14:
When dividing 0 by 64, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 111685.984375
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.

Advancing to step 15:
If we divide 0 by 64, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 111685.984375
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 result is 111685.984375 with a remainder of 0.0.
