53412149 ÷ 609 
Our goal is to divide 53412149 by 609.

Advancing to step 1:
609 can be fit into 5 0 times, resulting in a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Fetch the next digit (3) from the dividend, attach it to 5 and continue: 53 / 609

Advancing to step 2:
If we divide 53 by 609, we get 0 and a remainder of 53.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 53 leaves us with 53.
Take the next digit (4) from the dividend and append it to 53, then repeat: 534 / 609

Moving on to step 3:
534 divided by 609 is 0 with a remainder of 534.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 534, we end up with 534.
Append the next digit (1) from the dividend to 534 and continue with: 5341 / 609

Moving on to step 4:
609 can be fit into 5341 8 times, resulting in a remainder of 469.
The next digit of our result is 8. 
Result so far: 8.0
If we subtract 4872 from 5341, we get 469.
Fetch the next digit (2) from the dividend, attach it to 469 and continue: 4692 / 609

On to step 5:
The number 609 fits into 4692 7 times, leaving a remainder of 429.
Use 7 as the next digit of our solution. 
Result so far: 87.0
Deduct 4263 from 4692 and we're left with 429.
Fetch the next digit (1) from the dividend, attach it to 429 and continue: 4291 / 609

Let's proceed to step 6:
4291 divided by 609 is 7 with a remainder of 28.
Put 7 as the next digit of the answer. 
Result so far: 877.0
Deduct 4263 from 4291 and we're left with 28.
Fetch the next digit (4) from the dividend, attach it to 28 and continue: 284 / 609

Let's proceed to step 7:
609 goes into 284 0 times with a remainder of 284.
The next digit of our result is 0. 
Result so far: 8770.0
The remainder is 284 after subtracting 0 from 284.
Include the next digit (9) from the dividend after 284, then repeat: 2849 / 609

On to step 8:
609 can be fit into 2849 4 times, resulting in a remainder of 413.
The next digit of our result is 4. 
Result so far: 87704.0
The remainder is 413 after subtracting 2436 from 2849.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4130, and continue the process.

Step 9:
609 goes into 4130 6 times with a remainder of 476.
Put 6 as the next digit of the answer. 
Result so far: 87704.6
Subtract 3654 from 4130 to get 476.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4760, and continue the process.

Moving on to step 10:
609 goes into 4760 7 times with a remainder of 497.
The next digit of our result is 7. 
Result so far: 87704.67
The remainder is 497 after subtracting 4263 from 4760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4970, and continue the process.

Let's proceed to step 11:
609 can be fit into 4970 8 times, resulting in a remainder of 98.
The next digit of our result is 8. 
Result so far: 87704.678
Subtract 4872 from 4970 to get 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

Moving on to step 12:
If we divide 980 by 609, we get 1 and a remainder of 371.
Write down 1 as next digit of the result. 
Result so far: 87704.6781
Subtracting 609 from 980 leaves us with 371.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3710, and continue the process.

Step 13:
If we divide 3710 by 609, we get 6 and a remainder of 56.
Use 6 as the next digit of our solution. 
Result so far: 87704.67816
If we subtract 3654 from 3710, we get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Step 14:
When dividing 560 by 609, we get 0 with a remainder of 560.
Write down 0 as next digit of the result. 
Result so far: 87704.67816
Subtracting 0 from 560 leaves us with 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Advancing to step 15:
609 goes into 5600 9 times with a remainder of 119.
Use 9 as the next digit of our solution. 
Result so far: 87704.6781609
If we take 5481 away from 5600, we end up with 119.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1190, and continue the process.

Going ahead to step 16:
1190 divided by 609 is 1 with a remainder of 581.
Write down 1 as next digit of the result. 
Result so far: 87704.67816091
If we subtract 609 from 1190, we get 581.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5810, and continue the process.

The final result is 87704.67816091 with a remainder of 5.81e-07.
