Let's divide 53138318 by 901
We want to figure out the number of times 53138318 can be divided by 901.

Moving on to step 1:
When dividing 5 by 901, we get 0 with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Grab the next digit (3) from the dividend, add it to 5, then carry on: 53 / 901

Going ahead to step 2:
If we divide 53 by 901, we get 0 and a remainder of 53.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 53 after subtracting 0 from 53.
Bring next digit (1) of the dividend behind the 53 and repeat the process: 531 / 901

Moving on to step 3:
901 can be fit into 531 0 times, resulting in a remainder of 531.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 531, we get 531.
Bring next digit (3) of the dividend behind the 531 and repeat the process: 5313 / 901

Let's proceed to step 4:
5313 divided by 901 is 5 with a remainder of 808.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Subtracting 4505 from 5313 leaves us with 808.
Bring next digit (8) of the dividend behind the 808 and repeat the process: 8088 / 901

Step 5:
The number 901 fits into 8088 8 times, leaving a remainder of 880.
Use 8 as the next digit of our solution. 
Result so far: 58.0
If we take 7208 away from 8088, we end up with 880.
Append the next digit (3) from the dividend to 880 and continue with: 8803 / 901

Step 6:
The number 901 fits into 8803 9 times, leaving a remainder of 694.
Record the quotient 9 as the next digit in the result. 
Result so far: 589.0
If we take 8109 away from 8803, we end up with 694.
Take the next digit (1) from the dividend and append it to 694, then repeat: 6941 / 901

Advancing to step 7:
When dividing 6941 by 901, we get 7 with a remainder of 634.
The number 7 becomes the next digit in our result. 
Result so far: 5897.0
Deduct 6307 from 6941 and we're left with 634.
Include the next digit (8) from the dividend after 634, then repeat: 6348 / 901

Let's proceed to step 8:
901 goes into 6348 7 times with a remainder of 41.
Put 7 as the next digit of the answer. 
Result so far: 58977.0
Subtract 6307 from 6348 to get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Step 9:
When dividing 410 by 901, we get 0 with a remainder of 410.
Use 0 as the next digit of our solution. 
Result so far: 58977.0
If we take 0 away from 410, we end up with 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4100, and continue the process.

On to step 10:
The number 901 fits into 4100 4 times, leaving a remainder of 496.
Write down 4 as next digit of the result. 
Result so far: 58977.04
If we subtract 3604 from 4100, we get 496.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4960, and continue the process.

Step 11:
901 can be fit into 4960 5 times, resulting in a remainder of 455.
Use 5 as the next digit of our solution. 
Result so far: 58977.045
If we take 4505 away from 4960, we end up with 455.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4550, and continue the process.

On to step 12:
When dividing 4550 by 901, we get 5 with a remainder of 45.
Record the quotient 5 as the next digit in the result. 
Result so far: 58977.0455
Subtract 4505 from 4550 to get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Our division results in 58977.0455 with a remaining 0.00045.
