66811555 ÷ 458 
We're looking to find how many times 458 goes into 66811555.

On to step 1:
458 can be fit into 6 0 times, resulting in a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 458

Advancing to step 2:
If we divide 66 by 458, we get 0 and a remainder of 66.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 66 leaves us with 66.
Append the next digit (8) from the dividend to 66 and continue with: 668 / 458

Let's proceed to step 3:
The number 458 fits into 668 1 times, leaving a remainder of 210.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 458 from 668 leaves us with 210.
Fetch the next digit (1) from the dividend, attach it to 210 and continue: 2101 / 458

Moving on to step 4:
When dividing 2101 by 458, we get 4 with a remainder of 269.
Put 4 as the next digit of the answer. 
Result so far: 14.0
Deduct 1832 from 2101 and we're left with 269.
Fetch the next digit (1) from the dividend, attach it to 269 and continue: 2691 / 458

On to step 5:
458 can be fit into 2691 5 times, resulting in a remainder of 401.
Put 5 as the next digit of the answer. 
Result so far: 145.0
Deduct 2290 from 2691 and we're left with 401.
Bring next digit (5) of the dividend behind the 401 and repeat the process: 4015 / 458

Going ahead to step 6:
458 can be fit into 4015 8 times, resulting in a remainder of 351.
Put 8 as the next digit of the answer. 
Result so far: 1458.0
Subtracting 3664 from 4015 leaves us with 351.
Include the next digit (5) from the dividend after 351, then repeat: 3515 / 458

Going ahead to step 7:
458 can be fit into 3515 7 times, resulting in a remainder of 309.
Record the quotient 7 as the next digit in the result. 
Result so far: 14587.0
If we subtract 3206 from 3515, we get 309.
Fetch the next digit (5) from the dividend, attach it to 309 and continue: 3095 / 458

On to step 8:
458 can be fit into 3095 6 times, resulting in a remainder of 347.
The next digit of our result is 6. 
Result so far: 145876.0
The remainder is 347 after subtracting 2748 from 3095.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3470, and continue the process.

Moving on to step 9:
3470 divided by 458 is 7 with a remainder of 264.
Record the quotient 7 as the next digit in the result. 
Result so far: 145876.7
If we subtract 3206 from 3470, we get 264.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

Let's proceed to step 10:
If we divide 2640 by 458, we get 5 and a remainder of 350.
Use 5 as the next digit of our solution. 
Result so far: 145876.75
The remainder is 350 after subtracting 2290 from 2640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Moving on to step 11:
The number 458 fits into 3500 7 times, leaving a remainder of 294.
Put 7 as the next digit of the answer. 
Result so far: 145876.757
If we take 3206 away from 3500, we end up with 294.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2940, and continue the process.

Going ahead to step 12:
2940 divided by 458 is 6 with a remainder of 192.
Use 6 as the next digit of our solution. 
Result so far: 145876.7576
The remainder is 192 after subtracting 2748 from 2940.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

On to step 13:
If we divide 1920 by 458, we get 4 and a remainder of 88.
Put 4 as the next digit of the answer. 
Result so far: 145876.75764
Subtract 1832 from 1920 to get 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Let's proceed to step 14:
458 can be fit into 880 1 times, resulting in a remainder of 422.
Record the quotient 1 as the next digit in the result. 
Result so far: 145876.757641
The remainder is 422 after subtracting 458 from 880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4220, and continue the process.

On to step 15:
4220 divided by 458 is 9 with a remainder of 98.
The number 9 becomes the next digit in our result. 
Result so far: 145876.7576419
If we take 4122 away from 4220, we end up with 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

Going ahead to step 16:
458 goes into 980 2 times with a remainder of 64.
Write down 2 as next digit of the result. 
Result so far: 145876.75764192
Subtracting 916 from 980 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

The quotient of the division is 145876.75764192, and the remainder is 6.4e-08.
