We're dividing 52138054 by 90 
We're looking to find how many times 90 goes into 52138054.

Going ahead to step 1:
90 can be fit into 5 0 times, resulting in a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Append the next digit (2) from the dividend to 5 and continue with: 52 / 90

On to step 2:
When dividing 52 by 90, we get 0 with a remainder of 52.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 52 leaves us with 52.
Fetch the next digit (1) from the dividend, attach it to 52 and continue: 521 / 90

Advancing to step 3:
If we divide 521 by 90, we get 5 and a remainder of 71.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Subtracting 450 from 521 leaves us with 71.
Grab the next digit (3) from the dividend, add it to 71, then carry on: 713 / 90

Let's proceed to step 4:
The number 90 fits into 713 7 times, leaving a remainder of 83.
The next digit of our result is 7. 
Result so far: 57.0
If we subtract 630 from 713, we get 83.
Fetch the next digit (8) from the dividend, attach it to 83 and continue: 838 / 90

Going ahead to step 5:
90 can be fit into 838 9 times, resulting in a remainder of 28.
The number 9 becomes the next digit in our result. 
Result so far: 579.0
If we take 810 away from 838, we end up with 28.
Fetch the next digit (0) from the dividend, attach it to 28 and continue: 280 / 90

Let's proceed to step 6:
When dividing 280 by 90, we get 3 with a remainder of 10.
The number 3 becomes the next digit in our result. 
Result so far: 5793.0
Subtracting 270 from 280 leaves us with 10.
Bring next digit (5) of the dividend behind the 10 and repeat the process: 105 / 90

Moving on to step 7:
90 goes into 105 1 times with a remainder of 15.
The number 1 becomes the next digit in our result. 
Result so far: 57931.0
Deduct 90 from 105 and we're left with 15.
Fetch the next digit (4) from the dividend, attach it to 15 and continue: 154 / 90

Step 8:
If we divide 154 by 90, we get 1 and a remainder of 64.
Record the quotient 1 as the next digit in the result. 
Result so far: 579311.0
If we take 90 away from 154, we end up with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Going ahead to step 9:
640 divided by 90 is 7 with a remainder of 10.
Use 7 as the next digit of our solution. 
Result so far: 579311.7
Deduct 630 from 640 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 10:
90 can be fit into 100 1 times, resulting in a remainder of 10.
The next digit of our result is 1. 
Result so far: 579311.71
Deduct 90 from 100 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 11:
If we divide 100 by 90, we get 1 and a remainder of 10.
Write down 1 as next digit of the result. 
Result so far: 579311.711
If we take 90 away from 100, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

After the division, we end up with 579311.711 and a remainder of 0.001.
