Let's divide 66418941 by 458
Our goal is to divide 66418941 by 458.

On to step 1:
The number 458 fits into 6 0 times, leaving a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 66 / 458

Going ahead to step 2:
66 divided by 458 is 0 with a remainder of 66.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 66 after subtracting 0 from 66.
Fetch the next digit (4) from the dividend, attach it to 66 and continue: 664 / 458

Step 3:
The number 458 fits into 664 1 times, leaving a remainder of 206.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 458 away from 664, we end up with 206.
Take the next digit (1) from the dividend and append it to 206, then repeat: 2061 / 458

Advancing to step 4:
The number 458 fits into 2061 4 times, leaving a remainder of 229.
Write down 4 as next digit of the result. 
Result so far: 14.0
Subtracting 1832 from 2061 leaves us with 229.
Grab the next digit (8) from the dividend, add it to 229, then carry on: 2298 / 458

On to step 5:
458 can be fit into 2298 5 times, resulting in a remainder of 8.
Record the quotient 5 as the next digit in the result. 
Result so far: 145.0
Subtracting 2290 from 2298 leaves us with 8.
Grab the next digit (9) from the dividend, add it to 8, then carry on: 89 / 458

On to step 6:
If we divide 89 by 458, we get 0 and a remainder of 89.
Record the quotient 0 as the next digit in the result. 
Result so far: 1450.0
If we take 0 away from 89, we end up with 89.
Include the next digit (4) from the dividend after 89, then repeat: 894 / 458

Advancing to step 7:
894 divided by 458 is 1 with a remainder of 436.
The number 1 becomes the next digit in our result. 
Result so far: 14501.0
If we take 458 away from 894, we end up with 436.
Bring next digit (1) of the dividend behind the 436 and repeat the process: 4361 / 458

Advancing to step 8:
When dividing 4361 by 458, we get 9 with a remainder of 239.
Put 9 as the next digit of the answer. 
Result so far: 145019.0
Deduct 4122 from 4361 and we're left with 239.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2390, and continue the process.

On to step 9:
The number 458 fits into 2390 5 times, leaving a remainder of 100.
Record the quotient 5 as the next digit in the result. 
Result so far: 145019.5
Deduct 2290 from 2390 and we're left with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Going ahead to step 10:
458 can be fit into 1000 2 times, resulting in a remainder of 84.
The next digit of our result is 2. 
Result so far: 145019.52
Deduct 916 from 1000 and we're left with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Going ahead to step 11:
If we divide 840 by 458, we get 1 and a remainder of 382.
The next digit of our result is 1. 
Result so far: 145019.521
Deduct 458 from 840 and we're left with 382.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3820, and continue the process.

Going ahead to step 12:
3820 divided by 458 is 8 with a remainder of 156.
The next digit of our result is 8. 
Result so far: 145019.5218
The remainder is 156 after subtracting 3664 from 3820.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

Let's proceed to step 13:
If we divide 1560 by 458, we get 3 and a remainder of 186.
The number 3 becomes the next digit in our result. 
Result so far: 145019.52183
Subtract 1374 from 1560 to get 186.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

Let's proceed to step 14:
If we divide 1860 by 458, we get 4 and a remainder of 28.
The number 4 becomes the next digit in our result. 
Result so far: 145019.521834
If we take 1832 away from 1860, we end up 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 15:
458 goes into 280 0 times with a remainder of 280.
Put 0 as the next digit of the answer. 
Result so far: 145019.521834
If we take 0 away from 280, we end up with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Advancing to step 16:
The number 458 fits into 2800 6 times, leaving a remainder of 52.
The next digit of our result is 6. 
Result so far: 145019.52183406
If we take 2748 away from 2800, we end up with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Our division results in 145019.52183406 with a remaining 5.2e-08.
