73031387 ÷ 258 
Our goal is to divide 73031387 by 258.

Let's proceed to step 1:
258 can be fit into 7 0 times, resulting in a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Append the next digit (3) from the dividend to 7 and continue with: 73 / 258

Advancing to step 2:
258 can be fit into 73 0 times, resulting in a remainder of 73.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 73, we get 73.
Grab the next digit (0) from the dividend, add it to 73, then carry on: 730 / 258

Going ahead to step 3:
When dividing 730 by 258, we get 2 with a remainder of 214.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtract 516 from 730 to get 214.
Take the next digit (3) from the dividend and append it to 214, then repeat: 2143 / 258

Moving on to step 4:
The number 258 fits into 2143 8 times, leaving a remainder of 79.
Write down 8 as next digit of the result. 
Result so far: 28.0
If we subtract 2064 from 2143, we get 79.
Include the next digit (1) from the dividend after 79, then repeat: 791 / 258

Going ahead to step 5:
The number 258 fits into 791 3 times, leaving a remainder of 17.
Record the quotient 3 as the next digit in the result. 
Result so far: 283.0
Subtracting 774 from 791 leaves us with 17.
Grab the next digit (3) from the dividend, add it to 17, then carry on: 173 / 258

Going ahead to step 6:
258 goes into 173 0 times with a remainder of 173.
Put 0 as the next digit of the answer. 
Result so far: 2830.0
If we subtract 0 from 173, we get 173.
Take the next digit (8) from the dividend and append it to 173, then repeat: 1738 / 258

Let's proceed to step 7:
258 can be fit into 1738 6 times, resulting in a remainder of 190.
Write down 6 as next digit of the result. 
Result so far: 28306.0
Deduct 1548 from 1738 and we're left with 190.
Append the next digit (7) from the dividend to 190 and continue with: 1907 / 258

Going ahead to step 8:
When dividing 1907 by 258, we get 7 with a remainder of 101.
The next digit of our result is 7. 
Result so far: 283067.0
If we subtract 1806 from 1907, we get 101.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1010, and continue the process.

On to step 9:
When dividing 1010 by 258, we get 3 with a remainder of 236.
Record the quotient 3 as the next digit in the result. 
Result so far: 283067.3
Subtract 774 from 1010 to get 236.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

Advancing to step 10:
258 can be fit into 2360 9 times, resulting in a remainder of 38.
Record the quotient 9 as the next digit in the result. 
Result so far: 283067.39
Subtract 2322 from 2360 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

On to step 11:
258 can be fit into 380 1 times, resulting in a remainder of 122.
Use 1 as the next digit of our solution. 
Result so far: 283067.391
Subtracting 258 from 380 leaves us with 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

On to step 12:
The number 258 fits into 1220 4 times, leaving a remainder of 188.
The next digit of our result is 4. 
Result so far: 283067.3914
Deduct 1032 from 1220 and we're left with 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

Let's proceed to step 13:
When dividing 1880 by 258, we get 7 with a remainder of 74.
Put 7 as the next digit of the answer. 
Result so far: 283067.39147
If we subtract 1806 from 1880, we get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Advancing to step 14:
If we divide 740 by 258, we get 2 and a remainder of 224.
The next digit of our result is 2. 
Result so far: 283067.391472
Subtract 516 from 740 to get 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

Step 15:
The number 258 fits into 2240 8 times, leaving a remainder of 176.
The next digit of our result is 8. 
Result so far: 283067.3914728
Subtract 2064 from 2240 to get 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Step 16:
If we divide 1760 by 258, we get 6 and a remainder of 212.
The number 6 becomes the next digit in our result. 
Result so far: 283067.39147286
If we subtract 1548 from 1760, we get 212.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

The quotient of the division is 283067.39147286, and the remainder is 2.12e-07.
