21179185 divided by 260 
Our goal is to divide 21179185 by 260.

Moving on to step 1:
If we divide 2 by 260, we get 0 and a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 260

Going ahead to step 2:
If we divide 21 by 260, we get 0 and a remainder of 21.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 21, we get 21.
Grab the next digit (1) from the dividend, add it to 21, then carry on: 211 / 260

Let's proceed to step 3:
The number 260 fits into 211 0 times, leaving a remainder of 211.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 211 leaves us with 211.
Fetch the next digit (7) from the dividend, attach it to 211 and continue: 2117 / 260

Step 4:
The number 260 fits into 2117 8 times, leaving a remainder of 37.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Deduct 2080 from 2117 and we're left with 37.
Append the next digit (9) from the dividend to 37 and continue with: 379 / 260

Let's proceed to step 5:
260 can be fit into 379 1 times, resulting in a remainder of 119.
The next digit of our result is 1. 
Result so far: 81.0
Deduct 260 from 379 and we're left with 119.
Bring next digit (1) of the dividend behind the 119 and repeat the process: 1191 / 260

On to step 6:
When dividing 1191 by 260, we get 4 with a remainder of 151.
Record the quotient 4 as the next digit in the result. 
Result so far: 814.0
Subtracting 1040 from 1191 leaves us with 151.
Take the next digit (8) from the dividend and append it to 151, then repeat: 1518 / 260

Going ahead to step 7:
When dividing 1518 by 260, we get 5 with a remainder of 218.
Record the quotient 5 as the next digit in the result. 
Result so far: 8145.0
Subtracting 1300 from 1518 leaves us with 218.
Fetch the next digit (5) from the dividend, attach it to 218 and continue: 2185 / 260

Going ahead to step 8:
The number 260 fits into 2185 8 times, leaving a remainder of 105.
Use 8 as the next digit of our solution. 
Result so far: 81458.0
Deduct 2080 from 2185 and we're left with 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

Step 9:
260 goes into 1050 4 times with a remainder of 10.
The next digit of our result is 4. 
Result so far: 81458.4
If we take 1040 away from 1050, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 10:
If we divide 100 by 260, we get 0 and a remainder of 100.
Write down 0 as next digit of the result. 
Result so far: 81458.4
Subtracting 0 from 100 leaves us with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

On to step 11:
The number 260 fits into 1000 3 times, leaving a remainder of 220.
Record the quotient 3 as the next digit in the result. 
Result so far: 81458.403
The remainder is 220 after subtracting 780 from 1000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Moving on to step 12:
2200 divided by 260 is 8 with a remainder of 120.
Write down 8 as next digit of the result. 
Result so far: 81458.4038
If we take 2080 away from 2200, 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.

Step 13:
The number 260 fits into 1200 4 times, leaving a remainder of 160.
The number 4 becomes the next digit in our result. 
Result so far: 81458.40384
If we subtract 1040 from 1200, we get 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 14:
1600 divided by 260 is 6 with a remainder of 40.
The number 6 becomes the next digit in our result. 
Result so far: 81458.403846
If we take 1560 away from 1600, 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.

Step 15:
260 can be fit into 400 1 times, resulting in a remainder of 140.
Write down 1 as next digit of the result. 
Result so far: 81458.4038461
Subtract 260 from 400 to get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Let's proceed to step 16:
260 can be fit into 1400 5 times, resulting in a remainder of 100.
The next digit of our result is 5. 
Result so far: 81458.40384615
The remainder is 100 after subtracting 1300 from 1400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

In conclusion, the division gives 81458.40384615 with a balance of 1e-07.
