58981546 ÷ 312 
We want to figure out the number of times 58981546 can be divided by 312.

Step 1:
312 goes into 5 0 times with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Bring next digit (8) of the dividend behind the 5 and repeat the process: 58 / 312

Step 2:
58 divided by 312 is 0 with a remainder of 58.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 58 after subtracting 0 from 58.
Include the next digit (9) from the dividend after 58, then repeat: 589 / 312

Let's proceed to step 3:
When dividing 589 by 312, we get 1 with a remainder of 277.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 277 after subtracting 312 from 589.
Include the next digit (8) from the dividend after 277, then repeat: 2778 / 312

Moving on to step 4:
If we divide 2778 by 312, we get 8 and a remainder of 282.
Use 8 as the next digit of our solution. 
Result so far: 18.0
If we take 2496 away from 2778, we end up with 282.
Include the next digit (1) from the dividend after 282, then repeat: 2821 / 312

Moving on to step 5:
If we divide 2821 by 312, we get 9 and a remainder of 13.
The next digit of our result is 9. 
Result so far: 189.0
The remainder is 13 after subtracting 2808 from 2821.
Grab the next digit (5) from the dividend, add it to 13, then carry on: 135 / 312

Advancing to step 6:
When dividing 135 by 312, we get 0 with a remainder of 135.
Put 0 as the next digit of the answer. 
Result so far: 1890.0
The remainder is 135 after subtracting 0 from 135.
Fetch the next digit (4) from the dividend, attach it to 135 and continue: 1354 / 312

Let's proceed to step 7:
When dividing 1354 by 312, we get 4 with a remainder of 106.
Write down 4 as next digit of the result. 
Result so far: 18904.0
If we subtract 1248 from 1354, we get 106.
Grab the next digit (6) from the dividend, add it to 106, then carry on: 1066 / 312

Step 8:
When dividing 1066 by 312, we get 3 with a remainder of 130.
Write down 3 as next digit of the result. 
Result so far: 189043.0
The remainder is 130 after subtracting 936 from 1066.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

On to step 9:
If we divide 1300 by 312, we get 4 and a remainder of 52.
Write down 4 as next digit of the result. 
Result so far: 189043.4
Subtracting 1248 from 1300 leaves us with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

On to step 10:
The number 312 fits into 520 1 times, leaving a remainder of 208.
The next digit of our result is 1. 
Result so far: 189043.41
Deduct 312 from 520 and we're left with 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Let's proceed to step 11:
The number 312 fits into 2080 6 times, leaving a remainder of 208.
Write down 6 as next digit of the result. 
Result so far: 189043.416
If we subtract 1872 from 2080, we get 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

On to step 12:
When dividing 2080 by 312, we get 6 with a remainder of 208.
Put 6 as the next digit of the answer. 
Result so far: 189043.4166
Deduct 1872 from 2080 and we're left with 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

The final outcome is 189043.4166, with a leftover of 0.00208.
