We divide 20586086 by 526
We want to divide 20586086 by 526.

Moving on to step 1:
The number 526 fits into 2 0 times, leaving a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Take the next digit (0) from the dividend and append it to 2, then repeat: 20 / 526

Moving on to step 2:
526 goes into 20 0 times with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 20, we get 20.
Grab the next digit (5) from the dividend, add it to 20, then carry on: 205 / 526

Moving on to step 3:
526 can be fit into 205 0 times, resulting in a remainder of 205.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 205 to get 205.
Grab the next digit (8) from the dividend, add it to 205, then carry on: 2058 / 526

Moving on to step 4:
526 goes into 2058 3 times with a remainder of 480.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtracting 1578 from 2058 leaves us with 480.
Bring next digit (6) of the dividend behind the 480 and repeat the process: 4806 / 526

Step 5:
If we divide 4806 by 526, we get 9 and a remainder of 72.
Record the quotient 9 as the next digit in the result. 
Result so far: 39.0
If we subtract 4734 from 4806, we get 72.
Grab the next digit (0) from the dividend, add it to 72, then carry on: 720 / 526

Going ahead to step 6:
526 can be fit into 720 1 times, resulting in a remainder of 194.
The number 1 becomes the next digit in our result. 
Result so far: 391.0
If we subtract 526 from 720, we get 194.
Append the next digit (8) from the dividend to 194 and continue with: 1948 / 526

Advancing to step 7:
The number 526 fits into 1948 3 times, leaving a remainder of 370.
Put 3 as the next digit of the answer. 
Result so far: 3913.0
Subtract 1578 from 1948 to get 370.
Take the next digit (6) from the dividend and append it to 370, then repeat: 3706 / 526

Going ahead to step 8:
3706 divided by 526 is 7 with a remainder of 24.
Record the quotient 7 as the next digit in the result. 
Result so far: 39137.0
Subtracting 3682 from 3706 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 9:
When dividing 240 by 526, we get 0 with a remainder of 240.
The number 0 becomes the next digit in our result. 
Result so far: 39137.0
If we take 0 away from 240, we end up with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Step 10:
2400 divided by 526 is 4 with a remainder of 296.
The next digit of our result is 4. 
Result so far: 39137.04
Subtracting 2104 from 2400 leaves us with 296.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

Moving on to step 11:
526 goes into 2960 5 times with a remainder of 330.
The number 5 becomes the next digit in our result. 
Result so far: 39137.045
Deduct 2630 from 2960 and we're left with 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

Let's proceed to step 12:
526 goes into 3300 6 times with a remainder of 144.
Record the quotient 6 as the next digit in the result. 
Result so far: 39137.0456
Subtracting 3156 from 3300 leaves us with 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Advancing to step 13:
526 can be fit into 1440 2 times, resulting in a remainder of 388.
Use 2 as the next digit of our solution. 
Result so far: 39137.04562
Subtracting 1052 from 1440 leaves us with 388.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3880, and continue the process.

Going ahead to step 14:
526 goes into 3880 7 times with a remainder of 198.
Put 7 as the next digit of the answer. 
Result so far: 39137.045627
The remainder is 198 after subtracting 3682 from 3880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1980, and continue the process.

Moving on to step 15:
When dividing 1980 by 526, we get 3 with a remainder of 402.
The next digit of our result is 3. 
Result so far: 39137.0456273
Subtracting 1578 from 1980 leaves us with 402.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4020, and continue the process.

Advancing to step 16:
If we divide 4020 by 526, we get 7 and a remainder of 338.
The number 7 becomes the next digit in our result. 
Result so far: 39137.04562737
Subtracting 3682 from 4020 leaves us with 338.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3380, and continue the process.

After the division, we end up with 39137.04562737 and a remainder of 3.38e-07.
