66638792 divided by 258 
We want to divide 66638792 by 258.

Moving on to step 1:
258 goes into 6 0 times with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 258

Moving on to step 2:
When dividing 66 by 258, we get 0 with a remainder of 66.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 66 and we're left with 66.
Fetch the next digit (6) from the dividend, attach it to 66 and continue: 666 / 258

Going ahead to step 3:
258 goes into 666 2 times with a remainder of 150.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Deduct 516 from 666 and we're left with 150.
Grab the next digit (3) from the dividend, add it to 150, then carry on: 1503 / 258

Let's proceed to step 4:
If we divide 1503 by 258, we get 5 and a remainder of 213.
The number 5 becomes the next digit in our result. 
Result so far: 25.0
Subtract 1290 from 1503 to get 213.
Append the next digit (8) from the dividend to 213 and continue with: 2138 / 258

Moving on to step 5:
When dividing 2138 by 258, we get 8 with a remainder of 74.
Write down 8 as next digit of the result. 
Result so far: 258.0
Subtract 2064 from 2138 to get 74.
Include the next digit (7) from the dividend after 74, then repeat: 747 / 258

Step 6:
258 can be fit into 747 2 times, resulting in a remainder of 231.
The number 2 becomes the next digit in our result. 
Result so far: 2582.0
Deduct 516 from 747 and we're left with 231.
Take the next digit (9) from the dividend and append it to 231, then repeat: 2319 / 258

Moving on to step 7:
When dividing 2319 by 258, we get 8 with a remainder of 255.
The next digit of our result is 8. 
Result so far: 25828.0
The remainder is 255 after subtracting 2064 from 2319.
Include the next digit (2) from the dividend after 255, then repeat: 2552 / 258

Advancing to step 8:
When dividing 2552 by 258, we get 9 with a remainder of 230.
Use 9 as the next digit of our solution. 
Result so far: 258289.0
If we take 2322 away from 2552, we end up with 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

On to step 9:
258 can be fit into 2300 8 times, resulting in a remainder of 236.
The number 8 becomes the next digit in our result. 
Result so far: 258289.8
If we subtract 2064 from 2300, we 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.

Let's proceed to step 10:
If we divide 2360 by 258, we get 9 and a remainder of 38.
Record the quotient 9 as the next digit in the result. 
Result so far: 258289.89
Subtracting 2322 from 2360 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Let's proceed to step 11:
When dividing 380 by 258, we get 1 with a remainder of 122.
The number 1 becomes the next digit in our result. 
Result so far: 258289.891
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:
258 goes into 1220 4 times with a remainder of 188.
The number 4 becomes the next digit in our result. 
Result so far: 258289.8914
If we subtract 1032 from 1220, we get 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

On to step 13:
The number 258 fits into 1880 7 times, leaving a remainder of 74.
The next digit of our result is 7. 
Result so far: 258289.89147
If we take 1806 away from 1880, we end up with 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:
258 goes into 740 2 times with a remainder of 224.
Record the quotient 2 as the next digit in the result. 
Result so far: 258289.891472
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.

Going ahead to step 15:
2240 divided by 258 is 8 with a remainder of 176.
Put 8 as the next digit of the answer. 
Result so far: 258289.8914728
Deduct 2064 from 2240 and we're left with 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:
1760 divided by 258 is 6 with a remainder of 212.
Write down 6 as next digit of the result. 
Result so far: 258289.89147286
Deduct 1548 from 1760 and we're left with 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 258289.89147286, and the remainder is 2.12e-07.
