Let's divide 58980912 by 642
We want to figure out the number of times 58980912 can be divided by 642.

Step 1:
When dividing 5 by 642, we get 0 with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Fetch the next digit (8) from the dividend, attach it to 5 and continue: 58 / 642

Advancing to step 2:
When dividing 58 by 642, we get 0 with a remainder of 58.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 58, we get 58.
Bring next digit (9) of the dividend behind the 58 and repeat the process: 589 / 642

Advancing to step 3:
642 can be fit into 589 0 times, resulting in a remainder of 589.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 589 after subtracting 0 from 589.
Include the next digit (8) from the dividend after 589, then repeat: 5898 / 642

On to step 4:
5898 divided by 642 is 9 with a remainder of 120.
Put 9 as the next digit of the answer. 
Result so far: 9.0
The remainder is 120 after subtracting 5778 from 5898.
Append the next digit (0) from the dividend to 120 and continue with: 1200 / 642

Moving on to step 5:
The number 642 fits into 1200 1 times, leaving a remainder of 558.
Use 1 as the next digit of our solution. 
Result so far: 91.0
If we take 642 away from 1200, we end up with 558.
Take the next digit (9) from the dividend and append it to 558, then repeat: 5589 / 642

Advancing to step 6:
642 can be fit into 5589 8 times, resulting in a remainder of 453.
Use 8 as the next digit of our solution. 
Result so far: 918.0
Subtracting 5136 from 5589 leaves us with 453.
Include the next digit (1) from the dividend after 453, then repeat: 4531 / 642

Moving on to step 7:
642 goes into 4531 7 times with a remainder of 37.
Record the quotient 7 as the next digit in the result. 
Result so far: 9187.0
The remainder is 37 after subtracting 4494 from 4531.
Bring next digit (2) of the dividend behind the 37 and repeat the process: 372 / 642

Step 8:
When dividing 372 by 642, we get 0 with a remainder of 372.
The number 0 becomes the next digit in our result. 
Result so far: 91870.0
Deduct 0 from 372 and we're left with 372.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3720, and continue the process.

Let's proceed to step 9:
If we divide 3720 by 642, we get 5 and a remainder of 510.
Put 5 as the next digit of the answer. 
Result so far: 91870.5
If we take 3210 away from 3720, we end up with 510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5100, and continue the process.

Moving on to step 10:
5100 divided by 642 is 7 with a remainder of 606.
Use 7 as the next digit of our solution. 
Result so far: 91870.57
If we take 4494 away from 5100, we end up with 606.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6060, and continue the process.

Moving on to step 11:
If we divide 6060 by 642, we get 9 and a remainder of 282.
Write down 9 as next digit of the result. 
Result so far: 91870.579
Subtract 5778 from 6060 to get 282.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2820, and continue the process.

Going ahead to step 12:
When dividing 2820 by 642, we get 4 with a remainder of 252.
Use 4 as the next digit of our solution. 
Result so far: 91870.5794
Deduct 2568 from 2820 and we're left with 252.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

On to step 13:
642 can be fit into 2520 3 times, resulting in a remainder of 594.
Write down 3 as next digit of the result. 
Result so far: 91870.57943
The remainder is 594 after subtracting 1926 from 2520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5940, and continue the process.

Step 14:
If we divide 5940 by 642, we get 9 and a remainder of 162.
Use 9 as the next digit of our solution. 
Result so far: 91870.579439
The remainder is 162 after subtracting 5778 from 5940.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1620, and continue the process.

Step 15:
The number 642 fits into 1620 2 times, leaving a remainder of 336.
The next digit of our result is 2. 
Result so far: 91870.5794392
Subtract 1284 from 1620 to get 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

On to step 16:
3360 divided by 642 is 5 with a remainder of 150.
Record the quotient 5 as the next digit in the result. 
Result so far: 91870.57943925
If we take 3210 away from 3360, we end up with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

The final result is 91870.57943925 with a remainder of 1.5e-07.
