90344937 ÷ 580 
Let's see how many times 580 fits into 90344937.

Moving on to step 1:
580 can be fit into 9 0 times, resulting in a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Include the next digit (0) from the dividend after 9, then repeat: 90 / 580

Let's proceed to step 2:
When dividing 90 by 580, we get 0 with a remainder of 90.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 90, we get 90.
Grab the next digit (3) from the dividend, add it to 90, then carry on: 903 / 580

Going ahead to step 3:
580 can be fit into 903 1 times, resulting in a remainder of 323.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 323 after subtracting 580 from 903.
Fetch the next digit (4) from the dividend, attach it to 323 and continue: 3234 / 580

On to step 4:
3234 divided by 580 is 5 with a remainder of 334.
Write down 5 as next digit of the result. 
Result so far: 15.0
If we take 2900 away from 3234, we end up with 334.
Grab the next digit (4) from the dividend, add it to 334, then carry on: 3344 / 580

Let's proceed to step 5:
When dividing 3344 by 580, we get 5 with a remainder of 444.
Write down 5 as next digit of the result. 
Result so far: 155.0
Deduct 2900 from 3344 and we're left with 444.
Fetch the next digit (9) from the dividend, attach it to 444 and continue: 4449 / 580

Moving on to step 6:
When dividing 4449 by 580, we get 7 with a remainder of 389.
The next digit of our result is 7. 
Result so far: 1557.0
Deduct 4060 from 4449 and we're left with 389.
Fetch the next digit (3) from the dividend, attach it to 389 and continue: 3893 / 580

Advancing to step 7:
When dividing 3893 by 580, we get 6 with a remainder of 413.
The number 6 becomes the next digit in our result. 
Result so far: 15576.0
If we take 3480 away from 3893, we end up with 413.
Append the next digit (7) from the dividend to 413 and continue with: 4137 / 580

Step 8:
If we divide 4137 by 580, we get 7 and a remainder of 77.
Record the quotient 7 as the next digit in the result. 
Result so far: 155767.0
Subtract 4060 from 4137 to get 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Going ahead to step 9:
The number 580 fits into 770 1 times, leaving a remainder of 190.
The next digit of our result is 1. 
Result so far: 155767.1
Deduct 580 from 770 and we're left with 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Going ahead to step 10:
1900 divided by 580 is 3 with a remainder of 160.
Use 3 as the next digit of our solution. 
Result so far: 155767.13
Deduct 1740 from 1900 and we're left with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Step 11:
If we divide 1600 by 580, we get 2 and a remainder of 440.
Put 2 as the next digit of the answer. 
Result so far: 155767.132
If we subtract 1160 from 1600, we get 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Going ahead to step 12:
When dividing 4400 by 580, we get 7 with a remainder of 340.
Put 7 as the next digit of the answer. 
Result so far: 155767.1327
If we take 4060 away from 4400, we end up with 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Let's proceed to step 13:
If we divide 3400 by 580, we get 5 and a remainder of 500.
The next digit of our result is 5. 
Result so far: 155767.13275
Deduct 2900 from 3400 and we're left with 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Step 14:
5000 divided by 580 is 8 with a remainder of 360.
Use 8 as the next digit of our solution. 
Result so far: 155767.132758
Subtracting 4640 from 5000 leaves us with 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Let's proceed to step 15:
580 can be fit into 3600 6 times, resulting in a remainder of 120.
The next digit of our result is 6. 
Result so far: 155767.1327586
Deduct 3480 from 3600 and we're left 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.

Advancing to step 16:
1200 divided by 580 is 2 with a remainder of 40.
The number 2 becomes the next digit in our result. 
Result so far: 155767.13275862
If we take 1160 away from 1200, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

After the division, we end up with 155767.13275862 and a remainder of 4e-08.
