72123988 divided by 258 
We're looking to find how many times 258 goes into 72123988.

On to step 1:
The number 258 fits into 7 0 times, leaving a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Grab the next digit (2) from the dividend, add it to 7, then carry on: 72 / 258

Let's proceed to step 2:
The number 258 fits into 72 0 times, leaving a remainder of 72.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 72 and we're left with 72.
Bring next digit (1) of the dividend behind the 72 and repeat the process: 721 / 258

Going ahead to step 3:
258 can be fit into 721 2 times, resulting in a remainder of 205.
Use 2 as the next digit of our solution. 
Result so far: 2.0
The remainder is 205 after subtracting 516 from 721.
Fetch the next digit (2) from the dividend, attach it to 205 and continue: 2052 / 258

Let's proceed to step 4:
If we divide 2052 by 258, we get 7 and a remainder of 246.
Use 7 as the next digit of our solution. 
Result so far: 27.0
The remainder is 246 after subtracting 1806 from 2052.
Take the next digit (3) from the dividend and append it to 246, then repeat: 2463 / 258

Let's proceed to step 5:
258 goes into 2463 9 times with a remainder of 141.
The next digit of our result is 9. 
Result so far: 279.0
Subtract 2322 from 2463 to get 141.
Include the next digit (9) from the dividend after 141, then repeat: 1419 / 258

Let's proceed to step 6:
258 goes into 1419 5 times with a remainder of 129.
Record the quotient 5 as the next digit in the result. 
Result so far: 2795.0
Subtract 1290 from 1419 to get 129.
Fetch the next digit (8) from the dividend, attach it to 129 and continue: 1298 / 258

Advancing to step 7:
When dividing 1298 by 258, we get 5 with a remainder of 8.
The next digit of our result is 5. 
Result so far: 27955.0
Subtract 1290 from 1298 to get 8.
Append the next digit (8) from the dividend to 8 and continue with: 88 / 258

Moving on to step 8:
The number 258 fits into 88 0 times, leaving a remainder of 88.
Use 0 as the next digit of our solution. 
Result so far: 279550.0
Deduct 0 from 88 and we're left with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Going ahead to step 9:
880 divided by 258 is 3 with a remainder of 106.
The number 3 becomes the next digit in our result. 
Result so far: 279550.3
Subtract 774 from 880 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 10:
The number 258 fits into 1060 4 times, leaving a remainder of 28.
The number 4 becomes the next digit in our result. 
Result so far: 279550.34
Subtracting 1032 from 1060 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 11:
258 can be fit into 280 1 times, resulting in a remainder of 22.
Put 1 as the next digit of the answer. 
Result so far: 279550.341
Subtract 258 from 280 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 12:
258 goes into 220 0 times with a remainder of 220.
Use 0 as the next digit of our solution. 
Result so far: 279550.341
Subtract 0 from 220 to get 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Let's proceed to step 13:
2200 divided by 258 is 8 with a remainder of 136.
Record the quotient 8 as the next digit in the result. 
Result so far: 279550.34108
Deduct 2064 from 2200 and we're left with 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

On to step 14:
When dividing 1360 by 258, we get 5 with a remainder of 70.
Record the quotient 5 as the next digit in the result. 
Result so far: 279550.341085
If we subtract 1290 from 1360, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Advancing to step 15:
258 goes into 700 2 times with a remainder of 184.
The number 2 becomes the next digit in our result. 
Result so far: 279550.3410852
Subtract 516 from 700 to get 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Moving on to step 16:
The number 258 fits into 1840 7 times, leaving a remainder of 34.
Record the quotient 7 as the next digit in the result. 
Result so far: 279550.34108527
The remainder is 34 after subtracting 1806 from 1840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

After the division, we end up with 279550.34108527 and a remainder of 3.4e-08.
