We look at the division of 65121861 by 411 
We want to divide 65121861 by 411.

Step 1:
6 divided by 411 is 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Grab the next digit (5) from the dividend, add it to 6, then carry on: 65 / 411

Moving on to step 2:
65 divided by 411 is 0 with a remainder of 65.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 65, we get 65.
Include the next digit (1) from the dividend after 65, then repeat: 651 / 411

Let's proceed to step 3:
411 can be fit into 651 1 times, resulting in a remainder of 240.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 240 after subtracting 411 from 651.
Bring next digit (2) of the dividend behind the 240 and repeat the process: 2402 / 411

Moving on to step 4:
If we divide 2402 by 411, we get 5 and a remainder of 347.
Use 5 as the next digit of our solution. 
Result so far: 15.0
Subtract 2055 from 2402 to get 347.
Bring next digit (1) of the dividend behind the 347 and repeat the process: 3471 / 411

Advancing to step 5:
3471 divided by 411 is 8 with a remainder of 183.
Use 8 as the next digit of our solution. 
Result so far: 158.0
Subtracting 3288 from 3471 leaves us with 183.
Append the next digit (8) from the dividend to 183 and continue with: 1838 / 411

Moving on to step 6:
When dividing 1838 by 411, we get 4 with a remainder of 194.
The next digit of our result is 4. 
Result so far: 1584.0
Deduct 1644 from 1838 and we're left with 194.
Fetch the next digit (6) from the dividend, attach it to 194 and continue: 1946 / 411

Advancing to step 7:
The number 411 fits into 1946 4 times, leaving a remainder of 302.
Put 4 as the next digit of the answer. 
Result so far: 15844.0
Deduct 1644 from 1946 and we're left with 302.
Append the next digit (1) from the dividend to 302 and continue with: 3021 / 411

On to step 8:
411 can be fit into 3021 7 times, resulting in a remainder of 144.
The next digit of our result is 7. 
Result so far: 158447.0
The remainder is 144 after subtracting 2877 from 3021.
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 9:
411 can be fit into 1440 3 times, resulting in a remainder of 207.
The next digit of our result is 3. 
Result so far: 158447.3
Deduct 1233 from 1440 and we're left with 207.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2070, and continue the process.

Moving on to step 10:
411 goes into 2070 5 times with a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 158447.35
Deduct 2055 from 2070 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 11:
411 goes into 150 0 times with a remainder of 150.
Put 0 as the next digit of the answer. 
Result so far: 158447.35
The remainder is 150 after subtracting 0 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Step 12:
411 goes into 1500 3 times with a remainder of 267.
The number 3 becomes the next digit in our result. 
Result so far: 158447.3503
Subtract 1233 from 1500 to get 267.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2670, and continue the process.

Going ahead to step 13:
When dividing 2670 by 411, we get 6 with a remainder of 204.
Use 6 as the next digit of our solution. 
Result so far: 158447.35036
If we subtract 2466 from 2670, we get 204.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

Advancing to step 14:
411 goes into 2040 4 times with a remainder of 396.
Record the quotient 4 as the next digit in the result. 
Result so far: 158447.350364
If we take 1644 away from 2040, we end up with 396.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3960, and continue the process.

Going ahead to step 15:
If we divide 3960 by 411, we get 9 and a remainder of 261.
The next digit of our result is 9. 
Result so far: 158447.3503649
The remainder is 261 after subtracting 3699 from 3960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2610, and continue the process.

Step 16:
When dividing 2610 by 411, we get 6 with a remainder of 144.
The number 6 becomes the next digit in our result. 
Result so far: 158447.35036496
If we take 2466 away from 2610, we end up 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.

After the division, we end up with 158447.35036496 and a remainder of 1.44e-07.
