Let's divide 20125590 by 577
We're looking to find how many times 577 goes into 20125590.

Step 1:
When dividing 2 by 577, we get 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Take the next digit (0) from the dividend and append it to 2, then repeat: 20 / 577

Let's proceed to step 2:
577 can be fit into 20 0 times, resulting in a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 20 and we're left with 20.
Fetch the next digit (1) from the dividend, attach it to 20 and continue: 201 / 577

Let's proceed to step 3:
201 divided by 577 is 0 with a remainder of 201.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 201 and we're left with 201.
Include the next digit (2) from the dividend after 201, then repeat: 2012 / 577

On to step 4:
577 can be fit into 2012 3 times, resulting in a remainder of 281.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Deduct 1731 from 2012 and we're left with 281.
Take the next digit (5) from the dividend and append it to 281, then repeat: 2815 / 577

On to step 5:
When dividing 2815 by 577, we get 4 with a remainder of 507.
Use 4 as the next digit of our solution. 
Result so far: 34.0
Subtract 2308 from 2815 to get 507.
Grab the next digit (5) from the dividend, add it to 507, then carry on: 5075 / 577

On to step 6:
When dividing 5075 by 577, we get 8 with a remainder of 459.
Use 8 as the next digit of our solution. 
Result so far: 348.0
If we take 4616 away from 5075, we end up with 459.
Fetch the next digit (9) from the dividend, attach it to 459 and continue: 4599 / 577

Going ahead to step 7:
577 goes into 4599 7 times with a remainder of 560.
Write down 7 as next digit of the result. 
Result so far: 3487.0
If we subtract 4039 from 4599, we get 560.
Fetch the next digit (0) from the dividend, attach it to 560 and continue: 5600 / 577

Moving on to step 8:
The number 577 fits into 5600 9 times, leaving a remainder of 407.
Record the quotient 9 as the next digit in the result. 
Result so far: 34879.0
Subtract 5193 from 5600 to get 407.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4070, and continue the process.

On to step 9:
4070 divided by 577 is 7 with a remainder of 31.
The next digit of our result is 7. 
Result so far: 34879.7
The remainder is 31 after subtracting 4039 from 4070.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Going ahead to step 10:
310 divided by 577 is 0 with a remainder of 310.
Use 0 as the next digit of our solution. 
Result so far: 34879.7
Subtracting 0 from 310 leaves us with 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Let's proceed to step 11:
If we divide 3100 by 577, we get 5 and a remainder of 215.
Put 5 as the next digit of the answer. 
Result so far: 34879.705
If we take 2885 away from 3100, we end up with 215.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2150, and continue the process.

Step 12:
When dividing 2150 by 577, we get 3 with a remainder of 419.
The next digit of our result is 3. 
Result so far: 34879.7053
If we subtract 1731 from 2150, we get 419.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4190, and continue the process.

Let's proceed to step 13:
577 goes into 4190 7 times with a remainder of 151.
Use 7 as the next digit of our solution. 
Result so far: 34879.70537
Subtracting 4039 from 4190 leaves us with 151.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1510, and continue the process.

Let's proceed to step 14:
1510 divided by 577 is 2 with a remainder of 356.
The next digit of our result is 2. 
Result so far: 34879.705372
Subtracting 1154 from 1510 leaves us with 356.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3560, and continue the process.

Moving on to step 15:
If we divide 3560 by 577, we get 6 and a remainder of 98.
Use 6 as the next digit of our solution. 
Result so far: 34879.7053726
Subtract 3462 from 3560 to get 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

Going ahead to step 16:
When dividing 980 by 577, we get 1 with a remainder of 403.
Write down 1 as next digit of the result. 
Result so far: 34879.70537261
If we take 577 away from 980, we end up with 403.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4030, and continue the process.

The final outcome is 34879.70537261, with a leftover of 4.03e-07.
