We look at the division of 90568390 by 731 
We want to divide 90568390 by 731.

Step 1:
9 divided by 731 is 0 with a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Include the next digit (0) from the dividend after 9, then repeat: 90 / 731

Advancing to step 2:
731 can be fit into 90 0 times, resulting in a remainder of 90.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 90, we end up with 90.
Include the next digit (5) from the dividend after 90, then repeat: 905 / 731

Moving on to step 3:
731 goes into 905 1 times with a remainder of 174.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 731 from 905 leaves us with 174.
Take the next digit (6) from the dividend and append it to 174, then repeat: 1746 / 731

Advancing to step 4:
If we divide 1746 by 731, we get 2 and a remainder of 284.
Write down 2 as next digit of the result. 
Result so far: 12.0
Deduct 1462 from 1746 and we're left with 284.
Append the next digit (8) from the dividend to 284 and continue with: 2848 / 731

Moving on to step 5:
2848 divided by 731 is 3 with a remainder of 655.
Use 3 as the next digit of our solution. 
Result so far: 123.0
If we take 2193 away from 2848, we end up with 655.
Append the next digit (3) from the dividend to 655 and continue with: 6553 / 731

Advancing to step 6:
If we divide 6553 by 731, we get 8 and a remainder of 705.
The next digit of our result is 8. 
Result so far: 1238.0
If we subtract 5848 from 6553, we get 705.
Take the next digit (9) from the dividend and append it to 705, then repeat: 7059 / 731

On to step 7:
When dividing 7059 by 731, we get 9 with a remainder of 480.
Write down 9 as next digit of the result. 
Result so far: 12389.0
Subtracting 6579 from 7059 leaves us with 480.
Grab the next digit (0) from the dividend, add it to 480, then carry on: 4800 / 731

Going ahead to step 8:
The number 731 fits into 4800 6 times, leaving a remainder of 414.
The number 6 becomes the next digit in our result. 
Result so far: 123896.0
If we take 4386 away from 4800, we end up with 414.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4140, and continue the process.

Going ahead to step 9:
731 goes into 4140 5 times with a remainder of 485.
The number 5 becomes the next digit in our result. 
Result so far: 123896.5
Subtract 3655 from 4140 to get 485.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4850, and continue the process.

On to step 10:
731 can be fit into 4850 6 times, resulting in a remainder of 464.
The next digit of our result is 6. 
Result so far: 123896.56
Subtracting 4386 from 4850 leaves us with 464.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4640, and continue the process.

Advancing to step 11:
731 can be fit into 4640 6 times, resulting in a remainder of 254.
The next digit of our result is 6. 
Result so far: 123896.566
The remainder is 254 after subtracting 4386 from 4640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2540, and continue the process.

The final result is 123896.566 with a remainder of 0.0254.
