26158857 divided by 510 
We want to divide 26158857 by 510.

Let's proceed to step 1:
If we divide 2 by 510, we get 0 and a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Take the next digit (6) from the dividend and append it to 2, then repeat: 26 / 510

On to step 2:
510 goes into 26 0 times with a remainder of 26.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 26 after subtracting 0 from 26.
Fetch the next digit (1) from the dividend, attach it to 26 and continue: 261 / 510

Advancing to step 3:
261 divided by 510 is 0 with a remainder of 261.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 261, we end up with 261.
Append the next digit (5) from the dividend to 261 and continue with: 2615 / 510

On to step 4:
510 goes into 2615 5 times with a remainder of 65.
Put 5 as the next digit of the answer. 
Result so far: 5.0
The remainder is 65 after subtracting 2550 from 2615.
Append the next digit (8) from the dividend to 65 and continue with: 658 / 510

Step 5:
658 divided by 510 is 1 with a remainder of 148.
Put 1 as the next digit of the answer. 
Result so far: 51.0
Subtract 510 from 658 to get 148.
Take the next digit (8) from the dividend and append it to 148, then repeat: 1488 / 510

Advancing to step 6:
510 can be fit into 1488 2 times, resulting in a remainder of 468.
Use 2 as the next digit of our solution. 
Result so far: 512.0
Subtracting 1020 from 1488 leaves us with 468.
Include the next digit (5) from the dividend after 468, then repeat: 4685 / 510

Step 7:
510 can be fit into 4685 9 times, resulting in a remainder of 95.
Record the quotient 9 as the next digit in the result. 
Result so far: 5129.0
The remainder is 95 after subtracting 4590 from 4685.
Append the next digit (7) from the dividend to 95 and continue with: 957 / 510

Moving on to step 8:
510 can be fit into 957 1 times, resulting in a remainder of 447.
The next digit of our result is 1. 
Result so far: 51291.0
The remainder is 447 after subtracting 510 from 957.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4470, and continue the process.

Let's proceed to step 9:
510 can be fit into 4470 8 times, resulting in a remainder of 390.
Use 8 as the next digit of our solution. 
Result so far: 51291.8
Subtract 4080 from 4470 to get 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

Let's proceed to step 10:
If we divide 3900 by 510, we get 7 and a remainder of 330.
Use 7 as the next digit of our solution. 
Result so far: 51291.87
The remainder is 330 after subtracting 3570 from 3900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

Going ahead to step 11:
The number 510 fits into 3300 6 times, leaving a remainder of 240.
Put 6 as the next digit of the answer. 
Result so far: 51291.876
If we subtract 3060 from 3300, we get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Advancing to step 12:
If we divide 2400 by 510, we get 4 and a remainder of 360.
Record the quotient 4 as the next digit in the result. 
Result so far: 51291.8764
Subtract 2040 from 2400 to get 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Moving on to step 13:
3600 divided by 510 is 7 with a remainder of 30.
Write down 7 as next digit of the result. 
Result so far: 51291.87647
Deduct 3570 from 3600 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 14:
510 goes into 300 0 times with a remainder of 300.
Put 0 as the next digit of the answer. 
Result so far: 51291.87647
Deduct 0 from 300 and we're left with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Going ahead to step 15:
3000 divided by 510 is 5 with a remainder of 450.
Write down 5 as next digit of the result. 
Result so far: 51291.8764705
Deduct 2550 from 3000 and we're left with 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

On to step 16:
510 goes into 4500 8 times with a remainder of 420.
Write down 8 as next digit of the result. 
Result so far: 51291.87647058
Deduct 4080 from 4500 and we're left with 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

The final outcome is 51291.87647058, with a leftover of 4.2e-07.
