74390731 ÷ 726 
We want to figure out the number of times 74390731 can be divided by 726.

Let's proceed to step 1:
7 divided by 726 is 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Bring next digit (4) of the dividend behind the 7 and repeat the process: 74 / 726

Advancing to step 2:
74 divided by 726 is 0 with a remainder of 74.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 74 to get 74.
Bring next digit (3) of the dividend behind the 74 and repeat the process: 743 / 726

Going ahead to step 3:
When dividing 743 by 726, we get 1 with a remainder of 17.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 726 away from 743, we end up with 17.
Grab the next digit (9) from the dividend, add it to 17, then carry on: 179 / 726

Moving on to step 4:
726 can be fit into 179 0 times, resulting in a remainder of 179.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
Subtracting 0 from 179 leaves us with 179.
Bring next digit (0) of the dividend behind the 179 and repeat the process: 1790 / 726

On to step 5:
726 goes into 1790 2 times with a remainder of 338.
Put 2 as the next digit of the answer. 
Result so far: 102.0
Deduct 1452 from 1790 and we're left with 338.
Take the next digit (7) from the dividend and append it to 338, then repeat: 3387 / 726

Let's proceed to step 6:
If we divide 3387 by 726, we get 4 and a remainder of 483.
Write down 4 as next digit of the result. 
Result so far: 1024.0
If we take 2904 away from 3387, we end up with 483.
Take the next digit (3) from the dividend and append it to 483, then repeat: 4833 / 726

Advancing to step 7:
726 can be fit into 4833 6 times, resulting in a remainder of 477.
Put 6 as the next digit of the answer. 
Result so far: 10246.0
Deduct 4356 from 4833 and we're left with 477.
Fetch the next digit (1) from the dividend, attach it to 477 and continue: 4771 / 726

On to step 8:
726 can be fit into 4771 6 times, resulting in a remainder of 415.
Write down 6 as next digit of the result. 
Result so far: 102466.0
Subtracting 4356 from 4771 leaves us with 415.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4150, and continue the process.

Let's proceed to step 9:
The number 726 fits into 4150 5 times, leaving a remainder of 520.
Record the quotient 5 as the next digit in the result. 
Result so far: 102466.5
Subtracting 3630 from 4150 leaves us with 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

Step 10:
726 goes into 5200 7 times with a remainder of 118.
Use 7 as the next digit of our solution. 
Result so far: 102466.57
Deduct 5082 from 5200 and we're left with 118.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

Moving on to step 11:
When dividing 1180 by 726, we get 1 with a remainder of 454.
Write down 1 as next digit of the result. 
Result so far: 102466.571
The remainder is 454 after subtracting 726 from 1180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4540, and continue the process.

Moving on to step 12:
If we divide 4540 by 726, we get 6 and a remainder of 184.
Put 6 as the next digit of the answer. 
Result so far: 102466.5716
If we take 4356 away from 4540, we end up with 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Advancing to step 13:
726 goes into 1840 2 times with a remainder of 388.
The next digit of our result is 2. 
Result so far: 102466.57162
If we take 1452 away from 1840, we end up with 388.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3880, and continue the process.

Moving on to step 14:
If we divide 3880 by 726, we get 5 and a remainder of 250.
Put 5 as the next digit of the answer. 
Result so far: 102466.571625
Subtract 3630 from 3880 to get 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Step 15:
726 goes into 2500 3 times with a remainder of 322.
Put 3 as the next digit of the answer. 
Result so far: 102466.5716253
Subtracting 2178 from 2500 leaves us with 322.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3220, and continue the process.

Let's proceed to step 16:
726 goes into 3220 4 times with a remainder of 316.
Put 4 as the next digit of the answer. 
Result so far: 102466.57162534
The remainder is 316 after subtracting 2904 from 3220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3160, and continue the process.

The final result is 102466.57162534 with a remainder of 3.16e-07.
