We look at the division of 51540894 by 451 
We want to divide 51540894 by 451.

Step 1:
When dividing 5 by 451, we get 0 with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Include the next digit (1) from the dividend after 5, then repeat: 51 / 451

Advancing to step 2:
When dividing 51 by 451, we get 0 with a remainder of 51.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 51 after subtracting 0 from 51.
Take the next digit (5) from the dividend and append it to 51, then repeat: 515 / 451

Going ahead to step 3:
451 goes into 515 1 times with a remainder of 64.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 451 away from 515, we end up with 64.
Bring next digit (4) of the dividend behind the 64 and repeat the process: 644 / 451

Going ahead to step 4:
If we divide 644 by 451, we get 1 and a remainder of 193.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
Deduct 451 from 644 and we're left with 193.
Take the next digit (0) from the dividend and append it to 193, then repeat: 1930 / 451

Advancing to step 5:
When dividing 1930 by 451, we get 4 with a remainder of 126.
The number 4 becomes the next digit in our result. 
Result so far: 114.0
Deduct 1804 from 1930 and we're left with 126.
Take the next digit (8) from the dividend and append it to 126, then repeat: 1268 / 451

Step 6:
If we divide 1268 by 451, we get 2 and a remainder of 366.
Write down 2 as next digit of the result. 
Result so far: 1142.0
Deduct 902 from 1268 and we're left with 366.
Include the next digit (9) from the dividend after 366, then repeat: 3669 / 451

Step 7:
The number 451 fits into 3669 8 times, leaving a remainder of 61.
The next digit of our result is 8. 
Result so far: 11428.0
Subtracting 3608 from 3669 leaves us with 61.
Append the next digit (4) from the dividend to 61 and continue with: 614 / 451

Step 8:
If we divide 614 by 451, we get 1 and a remainder of 163.
The next digit of our result is 1. 
Result so far: 114281.0
If we take 451 away from 614, we end up 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.

Moving on to step 9:
451 can be fit into 1630 3 times, resulting in a remainder of 277.
Write down 3 as next digit of the result. 
Result so far: 114281.3
The remainder is 277 after subtracting 1353 from 1630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2770, and continue the process.

Let's proceed to step 10:
451 can be fit into 2770 6 times, resulting in a remainder of 64.
Put 6 as the next digit of the answer. 
Result so far: 114281.36
Deduct 2706 from 2770 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Moving on to step 11:
If we divide 640 by 451, we get 1 and a remainder of 189.
Use 1 as the next digit of our solution. 
Result so far: 114281.361
Subtracting 451 from 640 leaves us with 189.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1890, and continue the process.

On to step 12:
If we divide 1890 by 451, we get 4 and a remainder of 86.
Write down 4 as next digit of the result. 
Result so far: 114281.3614
Deduct 1804 from 1890 and we're left with 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Step 13:
The number 451 fits into 860 1 times, leaving a remainder of 409.
Write down 1 as next digit of the result. 
Result so far: 114281.36141
If we subtract 451 from 860, we get 409.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4090, and continue the process.

Moving on to step 14:
4090 divided by 451 is 9 with a remainder of 31.
The next digit of our result is 9. 
Result so far: 114281.361419
Deduct 4059 from 4090 and we're left with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Advancing to step 15:
310 divided by 451 is 0 with a remainder of 310.
Put 0 as the next digit of the answer. 
Result so far: 114281.361419
Deduct 0 from 310 and we're left with 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Advancing to step 16:
The number 451 fits into 3100 6 times, leaving a remainder of 394.
The number 6 becomes the next digit in our result. 
Result so far: 114281.36141906
Subtract 2706 from 3100 to get 394.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3940, and continue the process.

Our division results in 114281.36141906 with a remaining 3.94e-07.
