43590868 divided by 674 
Let's see how many times 674 fits into 43590868.

Moving on to step 1:
4 divided by 674 is 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Append the next digit (3) from the dividend to 4 and continue with: 43 / 674

On to step 2:
674 can be fit into 43 0 times, resulting in a remainder of 43.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 43, we get 43.
Take the next digit (5) from the dividend and append it to 43, then repeat: 435 / 674

Going ahead to step 3:
674 can be fit into 435 0 times, resulting in a remainder of 435.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 435 after subtracting 0 from 435.
Bring next digit (9) of the dividend behind the 435 and repeat the process: 4359 / 674

Let's proceed to step 4:
If we divide 4359 by 674, we get 6 and a remainder of 315.
Put 6 as the next digit of the answer. 
Result so far: 6.0
If we subtract 4044 from 4359, we get 315.
Take the next digit (0) from the dividend and append it to 315, then repeat: 3150 / 674

Step 5:
674 can be fit into 3150 4 times, resulting in a remainder of 454.
Use 4 as the next digit of our solution. 
Result so far: 64.0
Subtracting 2696 from 3150 leaves us with 454.
Include the next digit (8) from the dividend after 454, then repeat: 4548 / 674

Moving on to step 6:
If we divide 4548 by 674, we get 6 and a remainder of 504.
The next digit of our result is 6. 
Result so far: 646.0
If we take 4044 away from 4548, we end up with 504.
Bring next digit (6) of the dividend behind the 504 and repeat the process: 5046 / 674

On to step 7:
674 can be fit into 5046 7 times, resulting in a remainder of 328.
Use 7 as the next digit of our solution. 
Result so far: 6467.0
Deduct 4718 from 5046 and we're left with 328.
Append the next digit (8) from the dividend to 328 and continue with: 3288 / 674

Going ahead to step 8:
If we divide 3288 by 674, we get 4 and a remainder of 592.
Put 4 as the next digit of the answer. 
Result so far: 64674.0
Subtracting 2696 from 3288 leaves us with 592.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5920, and continue the process.

Going ahead to step 9:
When dividing 5920 by 674, we get 8 with a remainder of 528.
Put 8 as the next digit of the answer. 
Result so far: 64674.8
If we subtract 5392 from 5920, we get 528.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5280, and continue the process.

Let's proceed to step 10:
674 can be fit into 5280 7 times, resulting in a remainder of 562.
The number 7 becomes the next digit in our result. 
Result so far: 64674.87
The remainder is 562 after subtracting 4718 from 5280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5620, and continue the process.

Step 11:
The number 674 fits into 5620 8 times, leaving a remainder of 228.
The number 8 becomes the next digit in our result. 
Result so far: 64674.878
Deduct 5392 from 5620 and we're left with 228.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2280, and continue the process.

Advancing to step 12:
674 can be fit into 2280 3 times, resulting in a remainder of 258.
Use 3 as the next digit of our solution. 
Result so far: 64674.8783
If we subtract 2022 from 2280, we get 258.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2580, and continue the process.

Going ahead to step 13:
674 goes into 2580 3 times with a remainder of 558.
Use 3 as the next digit of our solution. 
Result so far: 64674.87833
Deduct 2022 from 2580 and we're left with 558.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5580, and continue the process.

The final result is 64674.87833 with a remainder of 0.000558.
