We're dividing 873620 by 64 
We want to figure out the number of times 873620 can be divided by 64.

Let's proceed to step 1:
When dividing 8 by 64, we get 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Fetch the next digit (7) from the dividend, attach it to 8 and continue: 87 / 64

Moving on to step 2:
If we divide 87 by 64, we get 1 and a remainder of 23.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 64 from 87 leaves us with 23.
Take the next digit (3) from the dividend and append it to 23, then repeat: 233 / 64

Advancing to step 3:
The number 64 fits into 233 3 times, leaving a remainder of 41.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
If we subtract 192 from 233, we get 41.
Fetch the next digit (6) from the dividend, attach it to 41 and continue: 416 / 64

Going ahead to step 4:
When dividing 416 by 64, we get 6 with a remainder of 32.
Use 6 as the next digit of our solution. 
Result so far: 136.0
Deduct 384 from 416 and we're left with 32.
Take the next digit (2) from the dividend and append it to 32, then repeat: 322 / 64

Moving on to step 5:
64 can be fit into 322 5 times, resulting in a remainder of 2.
Record the quotient 5 as the next digit in the result. 
Result so far: 1365.0
If we take 320 away from 322, we end up with 2.
Take the next digit (0) from the dividend and append it to 2, then repeat: 20 / 64

On to step 6:
If we divide 20 by 64, we get 0 and a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 13650.0
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 7:
200 divided by 64 is 3 with a remainder of 8.
The number 3 becomes the next digit in our result. 
Result so far: 13650.3
If we take 192 away from 200, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 8:
The number 64 fits into 80 1 times, leaving a remainder of 16.
Write down 1 as next digit of the result. 
Result so far: 13650.31
Subtracting 64 from 80 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 9:
160 divided by 64 is 2 with a remainder of 32.
Use 2 as the next digit of our solution. 
Result so far: 13650.312
If we subtract 128 from 160, we 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.

Let's proceed to step 10:
64 goes into 320 5 times with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 13650.3125
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:
0 divided by 64 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 13650.3125
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.

On to step 12:
64 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 13650.3125
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.

Our division results in 13650.3125 with a remaining 0.0.
