We're dividing 54553219 by 860 
We want to figure out the number of times 54553219 can be divided by 860.

Step 1:
860 goes into 5 0 times with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Take the next digit (4) from the dividend and append it to 5, then repeat: 54 / 860

Advancing to step 2:
860 goes into 54 0 times with a remainder of 54.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 54 leaves us with 54.
Fetch the next digit (5) from the dividend, attach it to 54 and continue: 545 / 860

Let's proceed to step 3:
When dividing 545 by 860, we get 0 with a remainder of 545.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 545 after subtracting 0 from 545.
Take the next digit (5) from the dividend and append it to 545, then repeat: 5455 / 860

Moving on to step 4:
If we divide 5455 by 860, we get 6 and a remainder of 295.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
Subtract 5160 from 5455 to get 295.
Append the next digit (3) from the dividend to 295 and continue with: 2953 / 860

Going ahead to step 5:
860 goes into 2953 3 times with a remainder of 373.
Use 3 as the next digit of our solution. 
Result so far: 63.0
Subtracting 2580 from 2953 leaves us with 373.
Append the next digit (2) from the dividend to 373 and continue with: 3732 / 860

Let's proceed to step 6:
860 can be fit into 3732 4 times, resulting in a remainder of 292.
Put 4 as the next digit of the answer. 
Result so far: 634.0
Subtracting 3440 from 3732 leaves us with 292.
Fetch the next digit (1) from the dividend, attach it to 292 and continue: 2921 / 860

Going ahead to step 7:
If we divide 2921 by 860, we get 3 and a remainder of 341.
The number 3 becomes the next digit in our result. 
Result so far: 6343.0
The remainder is 341 after subtracting 2580 from 2921.
Grab the next digit (9) from the dividend, add it to 341, then carry on: 3419 / 860

Going ahead to step 8:
The number 860 fits into 3419 3 times, leaving a remainder of 839.
Record the quotient 3 as the next digit in the result. 
Result so far: 63433.0
If we subtract 2580 from 3419, we get 839.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8390, and continue the process.

Advancing to step 9:
If we divide 8390 by 860, we get 9 and a remainder of 650.
The next digit of our result is 9. 
Result so far: 63433.9
Subtracting 7740 from 8390 leaves us with 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6500, and continue the process.

Moving on to step 10:
860 can be fit into 6500 7 times, resulting in a remainder of 480.
Write down 7 as next digit of the result. 
Result so far: 63433.97
If we take 6020 away from 6500, we end up with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Let's proceed to step 11:
860 can be fit into 4800 5 times, resulting in a remainder of 500.
Use 5 as the next digit of our solution. 
Result so far: 63433.975
The remainder is 500 after subtracting 4300 from 4800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Advancing to step 12:
The number 860 fits into 5000 5 times, leaving a remainder of 700.
The number 5 becomes the next digit in our result. 
Result so far: 63433.9755
Subtract 4300 from 5000 to get 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7000, and continue the process.

The quotient of the division is 63433.9755, and the remainder is 0.007.
