39468142 ÷ 743 
Our goal is to divide 39468142 by 743.

On to step 1:
The number 743 fits into 3 0 times, leaving a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Take the next digit (9) from the dividend and append it to 3, then repeat: 39 / 743

Going ahead to step 2:
If we divide 39 by 743, we get 0 and a remainder of 39.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 39 and we're left with 39.
Fetch the next digit (4) from the dividend, attach it to 39 and continue: 394 / 743

Step 3:
The number 743 fits into 394 0 times, leaving a remainder of 394.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 394, we get 394.
Fetch the next digit (6) from the dividend, attach it to 394 and continue: 3946 / 743

Going ahead to step 4:
If we divide 3946 by 743, we get 5 and a remainder of 231.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Deduct 3715 from 3946 and we're left with 231.
Take the next digit (8) from the dividend and append it to 231, then repeat: 2318 / 743

On to step 5:
When dividing 2318 by 743, we get 3 with a remainder of 89.
The next digit of our result is 3. 
Result so far: 53.0
Deduct 2229 from 2318 and we're left with 89.
Grab the next digit (1) from the dividend, add it to 89, then carry on: 891 / 743

Moving on to step 6:
743 can be fit into 891 1 times, resulting in a remainder of 148.
Write down 1 as next digit of the result. 
Result so far: 531.0
Subtracting 743 from 891 leaves us with 148.
Append the next digit (4) from the dividend to 148 and continue with: 1484 / 743

Going ahead to step 7:
If we divide 1484 by 743, we get 1 and a remainder of 741.
Record the quotient 1 as the next digit in the result. 
Result so far: 5311.0
The remainder is 741 after subtracting 743 from 1484.
Bring next digit (2) of the dividend behind the 741 and repeat the process: 7412 / 743

Going ahead to step 8:
7412 divided by 743 is 9 with a remainder of 725.
Write down 9 as next digit of the result. 
Result so far: 53119.0
The remainder is 725 after subtracting 6687 from 7412.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7250, and continue the process.

Advancing to step 9:
The number 743 fits into 7250 9 times, leaving a remainder of 563.
Use 9 as the next digit of our solution. 
Result so far: 53119.9
If we subtract 6687 from 7250, we get 563.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5630, and continue the process.

On to step 10:
5630 divided by 743 is 7 with a remainder of 429.
Put 7 as the next digit of the answer. 
Result so far: 53119.97
Subtract 5201 from 5630 to get 429.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4290, and continue the process.

Going ahead to step 11:
The number 743 fits into 4290 5 times, leaving a remainder of 575.
Write down 5 as next digit of the result. 
Result so far: 53119.975
Subtract 3715 from 4290 to get 575.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5750, and continue the process.

Let's proceed to step 12:
5750 divided by 743 is 7 with a remainder of 549.
Use 7 as the next digit of our solution. 
Result so far: 53119.9757
If we take 5201 away from 5750, we end up with 549.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5490, and continue the process.

Step 13:
743 can be fit into 5490 7 times, resulting in a remainder of 289.
The number 7 becomes the next digit in our result. 
Result so far: 53119.97577
If we take 5201 away from 5490, we end up with 289.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2890, and continue the process.

The quotient of the division is 53119.97577, and the remainder is 0.000289.
