Let's divide 81420004 by 261
Let's see how many times 261 fits into 81420004.

Step 1:
261 goes into 8 0 times with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Bring next digit (1) of the dividend behind the 8 and repeat the process: 81 / 261

Going ahead to step 2:
The number 261 fits into 81 0 times, leaving a remainder of 81.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 81 and we're left with 81.
Fetch the next digit (4) from the dividend, attach it to 81 and continue: 814 / 261

Advancing to step 3:
814 divided by 261 is 3 with a remainder of 31.
Write down 3 as next digit of the result. 
Result so far: 3.0
Deduct 783 from 814 and we're left with 31.
Append the next digit (2) from the dividend to 31 and continue with: 312 / 261

Step 4:
When dividing 312 by 261, we get 1 with a remainder of 51.
The next digit of our result is 1. 
Result so far: 31.0
If we take 261 away from 312, we end up with 51.
Append the next digit (0) from the dividend to 51 and continue with: 510 / 261

Let's proceed to step 5:
261 goes into 510 1 times with a remainder of 249.
Write down 1 as next digit of the result. 
Result so far: 311.0
If we subtract 261 from 510, we get 249.
Include the next digit (0) from the dividend after 249, then repeat: 2490 / 261

Going ahead to step 6:
261 can be fit into 2490 9 times, resulting in a remainder of 141.
The number 9 becomes the next digit in our result. 
Result so far: 3119.0
Subtract 2349 from 2490 to get 141.
Take the next digit (0) from the dividend and append it to 141, then repeat: 1410 / 261

Step 7:
When dividing 1410 by 261, we get 5 with a remainder of 105.
Use 5 as the next digit of our solution. 
Result so far: 31195.0
If we subtract 1305 from 1410, we get 105.
Take the next digit (4) from the dividend and append it to 105, then repeat: 1054 / 261

Step 8:
261 can be fit into 1054 4 times, resulting in a remainder of 10.
The number 4 becomes the next digit in our result. 
Result so far: 311954.0
If we take 1044 away from 1054, 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.

Advancing to step 9:
261 goes into 100 0 times with a remainder of 100.
Put 0 as the next digit of the answer. 
Result so far: 311954.0
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.

Moving on to step 10:
If we divide 1000 by 261, we get 3 and a remainder of 217.
The number 3 becomes the next digit in our result. 
Result so far: 311954.03
If we take 783 away from 1000, we end up with 217.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2170, and continue the process.

Let's proceed to step 11:
2170 divided by 261 is 8 with a remainder of 82.
The next digit of our result is 8. 
Result so far: 311954.038
The remainder is 82 after subtracting 2088 from 2170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Step 12:
820 divided by 261 is 3 with a remainder of 37.
Use 3 as the next digit of our solution. 
Result so far: 311954.0383
Subtracting 783 from 820 leaves us with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

On to step 13:
261 can be fit into 370 1 times, resulting in a remainder of 109.
The next digit of our result is 1. 
Result so far: 311954.03831
Subtract 261 from 370 to get 109.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1090, and continue the process.

Going ahead to step 14:
When dividing 1090 by 261, we get 4 with a remainder of 46.
Use 4 as the next digit of our solution. 
Result so far: 311954.038314
Subtracting 1044 from 1090 leaves us with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Let's proceed to step 15:
The number 261 fits into 460 1 times, leaving a remainder of 199.
Record the quotient 1 as the next digit in the result. 
Result so far: 311954.0383141
The remainder is 199 after subtracting 261 from 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1990, and continue the process.

On to step 16:
261 can be fit into 1990 7 times, resulting in a remainder of 163.
The next digit of our result is 7. 
Result so far: 311954.03831417
Deduct 1827 from 1990 and we're left with 163.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1630, and continue the process.

Our division results in 311954.03831417 with a remaining 1.63e-07.
