987172 divided by 64 
Our goal is to divide 987172 by 64.

Going ahead to step 1:
When dividing 9 by 64, we get 0 with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Append the next digit (8) from the dividend to 9 and continue with: 98 / 64

Going ahead to step 2:
64 goes into 98 1 times with a remainder of 34.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 64 from 98 to get 34.
Bring next digit (7) of the dividend behind the 34 and repeat the process: 347 / 64

Step 3:
64 can be fit into 347 5 times, resulting in a remainder of 27.
Write down 5 as next digit of the result. 
Result so far: 15.0
If we subtract 320 from 347, we get 27.
Bring next digit (1) of the dividend behind the 27 and repeat the process: 271 / 64

Let's proceed to step 4:
64 goes into 271 4 times with a remainder of 15.
Record the quotient 4 as the next digit in the result. 
Result so far: 154.0
Subtracting 256 from 271 leaves us with 15.
Bring next digit (7) of the dividend behind the 15 and repeat the process: 157 / 64

Advancing to step 5:
64 goes into 157 2 times with a remainder of 29.
Write down 2 as next digit of the result. 
Result so far: 1542.0
The remainder is 29 after subtracting 128 from 157.
Append the next digit (2) from the dividend to 29 and continue with: 292 / 64

Step 6:
64 goes into 292 4 times with a remainder of 36.
Use 4 as the next digit of our solution. 
Result so far: 15424.0
The remainder is 36 after subtracting 256 from 292.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 7:
360 divided by 64 is 5 with a remainder of 40.
The next digit of our result is 5. 
Result so far: 15424.5
If we subtract 320 from 360, we get 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 8:
64 goes into 400 6 times with a remainder of 16.
Put 6 as the next digit of the answer. 
Result so far: 15424.56
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.

Advancing to step 9:
64 goes into 160 2 times with a remainder of 32.
Write down 2 as next digit of the result. 
Result so far: 15424.562
The remainder is 32 after subtracting 128 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 10:
The number 64 fits into 320 5 times, leaving a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 15424.5625
Deduct 320 from 320 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.

Going ahead to step 11:
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: 15424.5625
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.

Step 12:
64 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 15424.5625
Subtract 0 from 0 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.

The final outcome is 15424.5625, with a leftover of 0.0.
