20113028 ÷ 258 
Our goal is to divide 20113028 by 258.

Going ahead to step 1:
258 goes into 2 0 times with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Grab the next digit (0) from the dividend, add it to 2, then carry on: 20 / 258

Going ahead to step 2:
258 can be fit into 20 0 times, resulting in a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 20 after subtracting 0 from 20.
Include the next digit (1) from the dividend after 20, then repeat: 201 / 258

On to step 3:
258 goes into 201 0 times with a remainder of 201.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 201, we get 201.
Append the next digit (1) from the dividend to 201 and continue with: 2011 / 258

Step 4:
When dividing 2011 by 258, we get 7 with a remainder of 205.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Deduct 1806 from 2011 and we're left with 205.
Fetch the next digit (3) from the dividend, attach it to 205 and continue: 2053 / 258

On to step 5:
258 goes into 2053 7 times with a remainder of 247.
The next digit of our result is 7. 
Result so far: 77.0
If we subtract 1806 from 2053, we get 247.
Append the next digit (0) from the dividend to 247 and continue with: 2470 / 258

Going ahead to step 6:
258 can be fit into 2470 9 times, resulting in a remainder of 148.
The number 9 becomes the next digit in our result. 
Result so far: 779.0
If we take 2322 away from 2470, we end up with 148.
Include the next digit (2) from the dividend after 148, then repeat: 1482 / 258

Moving on to step 7:
The number 258 fits into 1482 5 times, leaving a remainder of 192.
Record the quotient 5 as the next digit in the result. 
Result so far: 7795.0
Subtracting 1290 from 1482 leaves us with 192.
Include the next digit (8) from the dividend after 192, then repeat: 1928 / 258

On to step 8:
1928 divided by 258 is 7 with a remainder of 122.
The next digit of our result is 7. 
Result so far: 77957.0
If we take 1806 away from 1928, we end up 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.

Going ahead to step 9:
When dividing 1220 by 258, we get 4 with a remainder of 188.
Put 4 as the next digit of the answer. 
Result so far: 77957.4
The remainder is 188 after subtracting 1032 from 1220.
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 10:
1880 divided by 258 is 7 with a remainder of 74.
Put 7 as the next digit of the answer. 
Result so far: 77957.47
Subtract 1806 from 1880 to 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.

Moving on to step 11:
If we divide 740 by 258, we get 2 and a remainder of 224.
Record the quotient 2 as the next digit in the result. 
Result so far: 77957.472
The remainder is 224 after subtracting 516 from 740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

Advancing to step 12:
258 goes into 2240 8 times with a remainder of 176.
Record the quotient 8 as the next digit in the result. 
Result so far: 77957.4728
If we subtract 2064 from 2240, we 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.

Moving on to step 13:
258 goes into 1760 6 times with a remainder of 212.
Write down 6 as next digit of the result. 
Result so far: 77957.47286
The remainder is 212 after subtracting 1548 from 1760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

Moving on to step 14:
258 can be fit into 2120 8 times, resulting in a remainder of 56.
Record the quotient 8 as the next digit in the result. 
Result so far: 77957.472868
Subtract 2064 from 2120 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Step 15:
When dividing 560 by 258, we get 2 with a remainder of 44.
The next digit of our result is 2. 
Result so far: 77957.4728682
If we subtract 516 from 560, we get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 16:
The number 258 fits into 440 1 times, leaving a remainder of 182.
The next digit of our result is 1. 
Result so far: 77957.47286821
Deduct 258 from 440 and we're left with 182.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1820, and continue the process.

The final result is 77957.47286821 with a remainder of 1.82e-07.
