We want to divide 39984690 by 746.

Advancing to step 1:
The number 746 fits into 3 0 times, leaving a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 746

Moving on to step 2:
746 can be fit into 39 0 times, resulting in a remainder of 39.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 39 to get 39.
Take the next digit (9) from the dividend and append it to 39, then repeat: 399 / 746

On to step 3:
When dividing 399 by 746, we get 0 with a remainder of 399.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 399 after subtracting 0 from 399.
Fetch the next digit (8) from the dividend, attach it to 399 and continue: 3998 / 746

On to step 4:
3998 divided by 746 is 5 with a remainder of 268.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Subtract 3730 from 3998 to get 268.
Append the next digit (4) from the dividend to 268 and continue with: 2684 / 746

Step 5:
746 can be fit into 2684 3 times, resulting in a remainder of 446.
Use 3 as the next digit of our solution. 
Result so far: 53.0
Deduct 2238 from 2684 and we're left with 446.
Append the next digit (6) from the dividend to 446 and continue with: 4466 / 746

Moving on to step 6:
If we divide 4466 by 746, we get 5 and a remainder of 736.
The next digit of our result is 5. 
Result so far: 535.0
If we subtract 3730 from 4466, we get 736.
Grab the next digit (9) from the dividend, add it to 736, then carry on: 7369 / 746

On to step 7:
746 can be fit into 7369 9 times, resulting in a remainder of 655.
The number 9 becomes the next digit in our result. 
Result so far: 5359.0
Subtract 6714 from 7369 to get 655.
Fetch the next digit (0) from the dividend, attach it to 655 and continue: 6550 / 746

Going ahead to step 8:
6550 divided by 746 is 8 with a remainder of 582.
Write down 8 as next digit of the result. 
Result so far: 53598.0
Deduct 5968 from 6550 and we're left with 582.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5820, and continue the process.

Moving on to step 9:
5820 divided by 746 is 7 with a remainder of 598.
Put 7 as the next digit of the answer. 
Result so far: 53598.7
If we subtract 5222 from 5820, we get 598.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5980, and continue the process.

Going ahead to step 10:
If we divide 5980 by 746, we get 8 and a remainder of 12.
The next digit of our result is 8. 
Result so far: 53598.78
If we take 5968 away from 5980, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 11:
120 divided by 746 is 0 with a remainder of 120.
The next digit of our result is 0. 
Result so far: 53598.78
Subtracting 0 from 120 leaves us with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Let's proceed to step 12:
746 can be fit into 1200 1 times, resulting in a remainder of 454.
Write down 1 as next digit of the result. 
Result so far: 53598.7801
If we take 746 away from 1200, we end up with 454.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4540, and continue the process.

Going ahead to step 13:
When dividing 4540 by 746, we get 6 with a remainder of 64.
The next digit of our result is 6. 
Result so far: 53598.78016
The remainder is 64 after subtracting 4476 from 4540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Going ahead to step 14:
746 goes into 640 0 times with a remainder of 640.
The number 0 becomes the next digit in our result. 
Result so far: 53598.78016
If we take 0 away from 640, we end up with 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

Moving on to step 15:
746 can be fit into 6400 8 times, resulting in a remainder of 432.
The number 8 becomes the next digit in our result. 
Result so far: 53598.7801608
Subtracting 5968 from 6400 leaves us with 432.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4320, and continue the process.

Moving on to step 16:
4320 divided by 746 is 5 with a remainder of 590.
Record the quotient 5 as the next digit in the result. 
Result so far: 53598.78016085
If we take 3730 away from 4320, we end up with 590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5900, and continue the process.

The final outcome is 53598.78016085, with a leftover of 5.9e-07.
