We look at the division of 58531663 by 159 
We want to figure out the number of times 58531663 can be divided by 159.

On to step 1:
If we divide 5 by 159, we get 0 and a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Fetch the next digit (8) from the dividend, attach it to 5 and continue: 58 / 159

Going ahead to step 2:
58 divided by 159 is 0 with a remainder of 58.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 58, we get 58.
Fetch the next digit (5) from the dividend, attach it to 58 and continue: 585 / 159

On to step 3:
159 goes into 585 3 times with a remainder of 108.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtracting 477 from 585 leaves us with 108.
Fetch the next digit (3) from the dividend, attach it to 108 and continue: 1083 / 159

Advancing to step 4:
159 goes into 1083 6 times with a remainder of 129.
The next digit of our result is 6. 
Result so far: 36.0
If we take 954 away from 1083, we end up with 129.
Grab the next digit (1) from the dividend, add it to 129, then carry on: 1291 / 159

On to step 5:
The number 159 fits into 1291 8 times, leaving a remainder of 19.
The next digit of our result is 8. 
Result so far: 368.0
Subtract 1272 from 1291 to get 19.
Take the next digit (6) from the dividend and append it to 19, then repeat: 196 / 159

Moving on to step 6:
When dividing 196 by 159, we get 1 with a remainder of 37.
Use 1 as the next digit of our solution. 
Result so far: 3681.0
Subtracting 159 from 196 leaves us with 37.
Append the next digit (6) from the dividend to 37 and continue with: 376 / 159

On to step 7:
376 divided by 159 is 2 with a remainder of 58.
The next digit of our result is 2. 
Result so far: 36812.0
The remainder is 58 after subtracting 318 from 376.
Grab the next digit (3) from the dividend, add it to 58, then carry on: 583 / 159

Going ahead to step 8:
The number 159 fits into 583 3 times, leaving a remainder of 106.
Write down 3 as next digit of the result. 
Result so far: 368123.0
Subtract 477 from 583 to get 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Step 9:
1060 divided by 159 is 6 with a remainder of 106.
Record the quotient 6 as the next digit in the result. 
Result so far: 368123.6
If we take 954 away from 1060, we end up with 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Advancing to step 10:
1060 divided by 159 is 6 with a remainder of 106.
The number 6 becomes the next digit in our result. 
Result so far: 368123.66
Subtract 954 from 1060 to get 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

The quotient of the division is 368123.66, and the remainder is 0.106.
