51163461 ÷ 407 
Our goal is to divide 51163461 by 407.

Moving on to step 1:
If we divide 5 by 407, we get 0 and a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Bring next digit (1) of the dividend behind the 5 and repeat the process: 51 / 407

Step 2:
407 goes into 51 0 times with a remainder of 51.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 51 leaves us with 51.
Take the next digit (1) from the dividend and append it to 51, then repeat: 511 / 407

Advancing to step 3:
When dividing 511 by 407, we get 1 with a remainder of 104.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 407 from 511, we get 104.
Take the next digit (6) from the dividend and append it to 104, then repeat: 1046 / 407

Moving on to step 4:
When dividing 1046 by 407, we get 2 with a remainder of 232.
The next digit of our result is 2. 
Result so far: 12.0
If we take 814 away from 1046, we end up with 232.
Append the next digit (3) from the dividend to 232 and continue with: 2323 / 407

Let's proceed to step 5:
When dividing 2323 by 407, we get 5 with a remainder of 288.
Write down 5 as next digit of the result. 
Result so far: 125.0
Deduct 2035 from 2323 and we're left with 288.
Include the next digit (4) from the dividend after 288, then repeat: 2884 / 407

On to step 6:
If we divide 2884 by 407, we get 7 and a remainder of 35.
The number 7 becomes the next digit in our result. 
Result so far: 1257.0
Deduct 2849 from 2884 and we're left with 35.
Take the next digit (6) from the dividend and append it to 35, then repeat: 356 / 407

Advancing to step 7:
356 divided by 407 is 0 with a remainder of 356.
Put 0 as the next digit of the answer. 
Result so far: 12570.0
Subtracting 0 from 356 leaves us with 356.
Append the next digit (1) from the dividend to 356 and continue with: 3561 / 407

Step 8:
If we divide 3561 by 407, we get 8 and a remainder of 305.
The number 8 becomes the next digit in our result. 
Result so far: 125708.0
The remainder is 305 after subtracting 3256 from 3561.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3050, and continue the process.

Moving on to step 9:
407 can be fit into 3050 7 times, resulting in a remainder of 201.
The number 7 becomes the next digit in our result. 
Result so far: 125708.7
If we subtract 2849 from 3050, we get 201.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2010, and continue the process.

Let's proceed to step 10:
The number 407 fits into 2010 4 times, leaving a remainder of 382.
Put 4 as the next digit of the answer. 
Result so far: 125708.74
Subtract 1628 from 2010 to get 382.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3820, and continue the process.

On to step 11:
407 goes into 3820 9 times with a remainder of 157.
The next digit of our result is 9. 
Result so far: 125708.749
Deduct 3663 from 3820 and we're left with 157.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1570, and continue the process.

On to step 12:
407 can be fit into 1570 3 times, resulting in a remainder of 349.
The number 3 becomes the next digit in our result. 
Result so far: 125708.7493
If we subtract 1221 from 1570, we get 349.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3490, and continue the process.

Step 13:
3490 divided by 407 is 8 with a remainder of 234.
The number 8 becomes the next digit in our result. 
Result so far: 125708.74938
Deduct 3256 from 3490 and we're left with 234.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2340, and continue the process.

Going ahead to step 14:
2340 divided by 407 is 5 with a remainder of 305.
The number 5 becomes the next digit in our result. 
Result so far: 125708.749385
If we subtract 2035 from 2340, we get 305.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3050, and continue the process.

Going ahead to step 15:
If we divide 3050 by 407, we get 7 and a remainder of 201.
Put 7 as the next digit of the answer. 
Result so far: 125708.7493857
If we take 2849 away from 3050, we end up with 201.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2010, and continue the process.

On to step 16:
When dividing 2010 by 407, we get 4 with a remainder of 382.
Use 4 as the next digit of our solution. 
Result so far: 125708.74938574
The remainder is 382 after subtracting 1628 from 2010.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3820, and continue the process.

The quotient of the division is 125708.74938574, and the remainder is 3.82e-07.
