Let's divide 54211009 by 104
We want to figure out the number of times 54211009 can be divided by 104.

Moving on to step 1:
When dividing 5 by 104, we get 0 with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Bring next digit (4) of the dividend behind the 5 and repeat the process: 54 / 104

Moving on to step 2:
When dividing 54 by 104, we get 0 with a remainder of 54.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 54 leaves us with 54.
Fetch the next digit (2) from the dividend, attach it to 54 and continue: 542 / 104

Moving on to step 3:
104 goes into 542 5 times with a remainder of 22.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Deduct 520 from 542 and we're left with 22.
Grab the next digit (1) from the dividend, add it to 22, then carry on: 221 / 104

Advancing to step 4:
104 goes into 221 2 times with a remainder of 13.
The next digit of our result is 2. 
Result so far: 52.0
If we subtract 208 from 221, we get 13.
Append the next digit (1) from the dividend to 13 and continue with: 131 / 104

Going ahead to step 5:
104 goes into 131 1 times with a remainder of 27.
Put 1 as the next digit of the answer. 
Result so far: 521.0
The remainder is 27 after subtracting 104 from 131.
Append the next digit (0) from the dividend to 27 and continue with: 270 / 104

Advancing to step 6:
When dividing 270 by 104, we get 2 with a remainder of 62.
Use 2 as the next digit of our solution. 
Result so far: 5212.0
Subtract 208 from 270 to get 62.
Grab the next digit (0) from the dividend, add it to 62, then carry on: 620 / 104

On to step 7:
If we divide 620 by 104, we get 5 and a remainder of 100.
Write down 5 as next digit of the result. 
Result so far: 52125.0
Deduct 520 from 620 and we're left with 100.
Append the next digit (9) from the dividend to 100 and continue with: 1009 / 104

Step 8:
104 goes into 1009 9 times with a remainder of 73.
Put 9 as the next digit of the answer. 
Result so far: 521259.0
The remainder is 73 after subtracting 936 from 1009.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Going ahead to step 9:
If we divide 730 by 104, we get 7 and a remainder of 2.
Record the quotient 7 as the next digit in the result. 
Result so far: 521259.7
Deduct 728 from 730 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 10:
When dividing 20 by 104, we get 0 with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 521259.7
Deduct 0 from 20 and we're left with 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 11:
200 divided by 104 is 1 with a remainder of 96.
The next digit of our result is 1. 
Result so far: 521259.701
If we subtract 104 from 200, we get 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Going ahead to step 12:
104 goes into 960 9 times with a remainder of 24.
Record the quotient 9 as the next digit in the result. 
Result so far: 521259.7019
Deduct 936 from 960 and we're left 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.

Moving on to step 13:
240 divided by 104 is 2 with a remainder of 32.
The next digit of our result is 2. 
Result so far: 521259.70192
Deduct 208 from 240 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.

Step 14:
320 divided by 104 is 3 with a remainder of 8.
Write down 3 as next digit of the result. 
Result so far: 521259.701923
Deduct 312 from 320 and we're left 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.

Let's proceed to step 15:
The number 104 fits into 80 0 times, leaving a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 521259.701923
If we take 0 away from 80, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Let's proceed to step 16:
104 can be fit into 800 7 times, resulting in a remainder of 72.
The next digit of our result is 7. 
Result so far: 521259.70192307
Deduct 728 from 800 and we're left with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

The final outcome is 521259.70192307, with a leftover of 7.2e-08.
