90691257 ÷ 580 
Let's see how many times 580 fits into 90691257.

Going ahead to step 1:
9 divided by 580 is 0 with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Grab the next digit (0) from the dividend, add it to 9, then carry on: 90 / 580

Let's proceed to step 2:
When dividing 90 by 580, we get 0 with a remainder of 90.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 90, we end up with 90.
Include the next digit (6) from the dividend after 90, then repeat: 906 / 580

Let's proceed to step 3:
906 divided by 580 is 1 with a remainder of 326.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 580 away from 906, we end up with 326.
Take the next digit (9) from the dividend and append it to 326, then repeat: 3269 / 580

On to step 4:
If we divide 3269 by 580, we get 5 and a remainder of 369.
Put 5 as the next digit of the answer. 
Result so far: 15.0
Subtracting 2900 from 3269 leaves us with 369.
Append the next digit (1) from the dividend to 369 and continue with: 3691 / 580

On to step 5:
580 can be fit into 3691 6 times, resulting in a remainder of 211.
Record the quotient 6 as the next digit in the result. 
Result so far: 156.0
Deduct 3480 from 3691 and we're left with 211.
Fetch the next digit (2) from the dividend, attach it to 211 and continue: 2112 / 580

Moving on to step 6:
When dividing 2112 by 580, we get 3 with a remainder of 372.
Use 3 as the next digit of our solution. 
Result so far: 1563.0
Subtract 1740 from 2112 to get 372.
Fetch the next digit (5) from the dividend, attach it to 372 and continue: 3725 / 580

Going ahead to step 7:
580 can be fit into 3725 6 times, resulting in a remainder of 245.
The next digit of our result is 6. 
Result so far: 15636.0
Deduct 3480 from 3725 and we're left with 245.
Take the next digit (7) from the dividend and append it to 245, then repeat: 2457 / 580

Advancing to step 8:
When dividing 2457 by 580, we get 4 with a remainder of 137.
Write down 4 as next digit of the result. 
Result so far: 156364.0
Deduct 2320 from 2457 and we're left with 137.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1370, and continue the process.

Moving on to step 9:
580 goes into 1370 2 times with a remainder of 210.
Record the quotient 2 as the next digit in the result. 
Result so far: 156364.2
Subtracting 1160 from 1370 leaves us with 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Let's proceed to step 10:
2100 divided by 580 is 3 with a remainder of 360.
The number 3 becomes the next digit in our result. 
Result so far: 156364.23
The remainder is 360 after subtracting 1740 from 2100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Advancing to step 11:
The number 580 fits into 3600 6 times, leaving a remainder of 120.
The number 6 becomes the next digit in our result. 
Result so far: 156364.236
If we take 3480 away from 3600, we end up 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.

On to step 12:
1200 divided by 580 is 2 with a remainder of 40.
Record the quotient 2 as the next digit in the result. 
Result so far: 156364.2362
Deduct 1160 from 1200 and we're left 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.

Advancing to step 13:
If we divide 400 by 580, we get 0 and a remainder of 400.
Put 0 as the next digit of the answer. 
Result so far: 156364.2362
Subtracting 0 from 400 leaves us with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Step 14:
4000 divided by 580 is 6 with a remainder of 520.
Put 6 as the next digit of the answer. 
Result so far: 156364.236206
Subtracting 3480 from 4000 leaves us with 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

Going ahead to step 15:
580 can be fit into 5200 8 times, resulting in a remainder of 560.
Use 8 as the next digit of our solution. 
Result so far: 156364.2362068
Deduct 4640 from 5200 and we're left with 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Step 16:
The number 580 fits into 5600 9 times, leaving a remainder of 380.
Write down 9 as next digit of the result. 
Result so far: 156364.23620689
Subtract 5220 from 5600 to get 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

The final result is 156364.23620689 with a remainder of 3.8e-07.
