58421665 divided by 746 
We want to figure out the number of times 58421665 can be divided by 746.

On to step 1:
746 can be fit into 5 0 times, resulting in a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Grab the next digit (8) from the dividend, add it to 5, then carry on: 58 / 746

On to step 2:
746 goes into 58 0 times with a remainder of 58.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 58 and we're left with 58.
Append the next digit (4) from the dividend to 58 and continue with: 584 / 746

On to step 3:
584 divided by 746 is 0 with a remainder of 584.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 584, we get 584.
Fetch the next digit (2) from the dividend, attach it to 584 and continue: 5842 / 746

Step 4:
5842 divided by 746 is 7 with a remainder of 620.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
If we take 5222 away from 5842, we end up with 620.
Take the next digit (1) from the dividend and append it to 620, then repeat: 6201 / 746

Step 5:
6201 divided by 746 is 8 with a remainder of 233.
Put 8 as the next digit of the answer. 
Result so far: 78.0
Subtracting 5968 from 6201 leaves us with 233.
Fetch the next digit (6) from the dividend, attach it to 233 and continue: 2336 / 746

Let's proceed to step 6:
746 goes into 2336 3 times with a remainder of 98.
The next digit of our result is 3. 
Result so far: 783.0
The remainder is 98 after subtracting 2238 from 2336.
Include the next digit (6) from the dividend after 98, then repeat: 986 / 746

Moving on to step 7:
When dividing 986 by 746, we get 1 with a remainder of 240.
The next digit of our result is 1. 
Result so far: 7831.0
If we take 746 away from 986, we end up with 240.
Include the next digit (5) from the dividend after 240, then repeat: 2405 / 746

On to step 8:
When dividing 2405 by 746, we get 3 with a remainder of 167.
The number 3 becomes the next digit in our result. 
Result so far: 78313.0
Subtracting 2238 from 2405 leaves us with 167.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1670, and continue the process.

Going ahead to step 9:
746 goes into 1670 2 times with a remainder of 178.
The number 2 becomes the next digit in our result. 
Result so far: 78313.2
Subtract 1492 from 1670 to 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.

Moving on to step 10:
746 can be fit into 1780 2 times, resulting in a remainder of 288.
The number 2 becomes the next digit in our result. 
Result so far: 78313.22
Deduct 1492 from 1780 and we're left with 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

The quotient of the division is 78313.22, and the remainder is 0.288.
