Let's divide 98880574 by 258
We want to figure out the number of times 98880574 can be divided by 258.

Going ahead to step 1:
258 goes into 9 0 times with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Take the next digit (8) from the dividend and append it to 9, then repeat: 98 / 258

Moving on to step 2:
If we divide 98 by 258, we get 0 and a remainder of 98.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 98 after subtracting 0 from 98.
Append the next digit (8) from the dividend to 98 and continue with: 988 / 258

Advancing to step 3:
988 divided by 258 is 3 with a remainder of 214.
Write down 3 as next digit of the result. 
Result so far: 3.0
If we take 774 away from 988, we end up with 214.
Include the next digit (8) from the dividend after 214, then repeat: 2148 / 258

On to step 4:
The number 258 fits into 2148 8 times, leaving a remainder of 84.
The next digit of our result is 8. 
Result so far: 38.0
The remainder is 84 after subtracting 2064 from 2148.
Take the next digit (0) from the dividend and append it to 84, then repeat: 840 / 258

Going ahead to step 5:
258 can be fit into 840 3 times, resulting in a remainder of 66.
Use 3 as the next digit of our solution. 
Result so far: 383.0
Subtract 774 from 840 to get 66.
Take the next digit (5) from the dividend and append it to 66, then repeat: 665 / 258

Moving on to step 6:
665 divided by 258 is 2 with a remainder of 149.
Put 2 as the next digit of the answer. 
Result so far: 3832.0
Subtract 516 from 665 to get 149.
Grab the next digit (7) from the dividend, add it to 149, then carry on: 1497 / 258

Going ahead to step 7:
If we divide 1497 by 258, we get 5 and a remainder of 207.
Record the quotient 5 as the next digit in the result. 
Result so far: 38325.0
If we take 1290 away from 1497, we end up with 207.
Bring next digit (4) of the dividend behind the 207 and repeat the process: 2074 / 258

Moving on to step 8:
258 goes into 2074 8 times with a remainder of 10.
The number 8 becomes the next digit in our result. 
Result so far: 383258.0
If we take 2064 away from 2074, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 9:
258 goes into 100 0 times with a remainder of 100.
Write down 0 as next digit of the result. 
Result so far: 383258.0
Subtract 0 from 100 to get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Moving on to step 10:
When dividing 1000 by 258, we get 3 with a remainder of 226.
Write down 3 as next digit of the result. 
Result so far: 383258.03
Deduct 774 from 1000 and we're left with 226.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2260, and continue the process.

Moving on to step 11:
The number 258 fits into 2260 8 times, leaving a remainder of 196.
Record the quotient 8 as the next digit in the result. 
Result so far: 383258.038
The remainder is 196 after subtracting 2064 from 2260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

Moving on to step 12:
When dividing 1960 by 258, we get 7 with a remainder of 154.
Write down 7 as next digit of the result. 
Result so far: 383258.0387
Deduct 1806 from 1960 and we're left with 154.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1540, and continue the process.

Moving on to step 13:
258 can be fit into 1540 5 times, resulting in a remainder of 250.
Record the quotient 5 as the next digit in the result. 
Result so far: 383258.03875
The remainder is 250 after subtracting 1290 from 1540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Step 14:
2500 divided by 258 is 9 with a remainder of 178.
Write down 9 as next digit of the result. 
Result so far: 383258.038759
If we subtract 2322 from 2500, we get 178.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1780, and continue the process.

Step 15:
When dividing 1780 by 258, we get 6 with a remainder of 232.
Record the quotient 6 as the next digit in the result. 
Result so far: 383258.0387596
If we subtract 1548 from 1780, we get 232.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

On to step 16:
258 can be fit into 2320 8 times, resulting in a remainder of 256.
Write down 8 as next digit of the result. 
Result so far: 383258.03875968
The remainder is 256 after subtracting 2064 from 2320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

After the division, we end up with 383258.03875968 and a remainder of 2.56e-07.
