58390989 ÷ 16 
Let's see how many times 16 fits into 58390989.

Advancing to step 1:
If we divide 5 by 16, we get 0 and a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Take the next digit (8) from the dividend and append it to 5, then repeat: 58 / 16

Moving on to step 2:
When dividing 58 by 16, we get 3 with a remainder of 10.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
The remainder is 10 after subtracting 48 from 58.
Bring next digit (3) of the dividend behind the 10 and repeat the process: 103 / 16

Moving on to step 3:
103 divided by 16 is 6 with a remainder of 7.
Put 6 as the next digit of the answer. 
Result so far: 36.0
Subtracting 96 from 103 leaves us with 7.
Append the next digit (9) from the dividend to 7 and continue with: 79 / 16

Let's proceed to step 4:
If we divide 79 by 16, we get 4 and a remainder of 15.
Write down 4 as next digit of the result. 
Result so far: 364.0
Subtract 64 from 79 to get 15.
Take the next digit (0) from the dividend and append it to 15, then repeat: 150 / 16

Going ahead to step 5:
When dividing 150 by 16, we get 9 with a remainder of 6.
Put 9 as the next digit of the answer. 
Result so far: 3649.0
If we take 144 away from 150, we end up with 6.
Include the next digit (9) from the dividend after 6, then repeat: 69 / 16

Let's proceed to step 6:
16 can be fit into 69 4 times, resulting in a remainder of 5.
Put 4 as the next digit of the answer. 
Result so far: 36494.0
Subtracting 64 from 69 leaves us with 5.
Bring next digit (8) of the dividend behind the 5 and repeat the process: 58 / 16

Step 7:
When dividing 58 by 16, we get 3 with a remainder of 10.
Record the quotient 3 as the next digit in the result. 
Result so far: 364943.0
If we take 48 away from 58, we end up with 10.
Fetch the next digit (9) from the dividend, attach it to 10 and continue: 109 / 16

Let's proceed to step 8:
When dividing 109 by 16, we get 6 with a remainder of 13.
Put 6 as the next digit of the answer. 
Result so far: 3649436.0
Subtracting 96 from 109 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

On to step 9:
130 divided by 16 is 8 with a remainder of 2.
The number 8 becomes the next digit in our result. 
Result so far: 3649436.8
Deduct 128 from 130 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.

Moving on to step 10:
20 divided by 16 is 1 with a remainder of 4.
The next digit of our result is 1. 
Result so far: 3649436.81
Deduct 16 from 20 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 11:
16 goes into 40 2 times with a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 3649436.812
If we subtract 32 from 40, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 12:
If we divide 80 by 16, we get 5 and a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 3649436.8125
Deduct 80 from 80 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 13:
The number 16 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 3649436.8125
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 14:
If we divide 0 by 16, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 3649436.8125
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 3649436.8125 with a remaining 0.0.
