12125547 ÷ 64 
Let's see how many times 64 fits into 12125547.

On to step 1:
1 divided by 64 is 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 64

On to step 2:
If we divide 12 by 64, we get 0 and a remainder of 12.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 12 to get 12.
Fetch the next digit (1) from the dividend, attach it to 12 and continue: 121 / 64

Advancing to step 3:
64 can be fit into 121 1 times, resulting in a remainder of 57.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 64 from 121 and we're left with 57.
Fetch the next digit (2) from the dividend, attach it to 57 and continue: 572 / 64

Advancing to step 4:
572 divided by 64 is 8 with a remainder of 60.
Put 8 as the next digit of the answer. 
Result so far: 18.0
If we take 512 away from 572, we end up with 60.
Bring next digit (5) of the dividend behind the 60 and repeat the process: 605 / 64

Going ahead to step 5:
When dividing 605 by 64, we get 9 with a remainder of 29.
The number 9 becomes the next digit in our result. 
Result so far: 189.0
If we subtract 576 from 605, we get 29.
Bring next digit (5) of the dividend behind the 29 and repeat the process: 295 / 64

Step 6:
64 goes into 295 4 times with a remainder of 39.
Record the quotient 4 as the next digit in the result. 
Result so far: 1894.0
Deduct 256 from 295 and we're left with 39.
Fetch the next digit (4) from the dividend, attach it to 39 and continue: 394 / 64

Advancing to step 7:
64 can be fit into 394 6 times, resulting in a remainder of 10.
The number 6 becomes the next digit in our result. 
Result so far: 18946.0
Subtract 384 from 394 to get 10.
Take the next digit (7) from the dividend and append it to 10, then repeat: 107 / 64

Let's proceed to step 8:
64 can be fit into 107 1 times, resulting in a remainder of 43.
The number 1 becomes the next digit in our result. 
Result so far: 189461.0
The remainder is 43 after subtracting 64 from 107.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Step 9:
64 can be fit into 430 6 times, resulting in a remainder of 46.
Put 6 as the next digit of the answer. 
Result so far: 189461.6
If we take 384 away from 430, we end up with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

On to step 10:
64 goes into 460 7 times with a remainder of 12.
The next digit of our result is 7. 
Result so far: 189461.67
Subtracting 448 from 460 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 11:
If we divide 120 by 64, we get 1 and a remainder of 56.
Use 1 as the next digit of our solution. 
Result so far: 189461.671
Deduct 64 from 120 and we're left with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Moving on to step 12:
The number 64 fits into 560 8 times, leaving a remainder of 48.
The next digit of our result is 8. 
Result so far: 189461.6718
Subtract 512 from 560 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.

Step 13:
64 can be fit into 480 7 times, resulting in a remainder of 32.
Write down 7 as next digit of the result. 
Result so far: 189461.67187
Deduct 448 from 480 and we're left 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 14:
64 can be fit into 320 5 times, resulting in a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 189461.671875
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.

Advancing to step 15:
64 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 189461.671875
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.

Let's proceed to step 16:
64 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 189461.671875
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 outcome is 189461.671875, with a leftover of 0.0.
