Let's divide 51578415 by 977
We want to figure out the number of times 51578415 can be divided by 977.

On to step 1:
The number 977 fits into 5 0 times, leaving a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Include the next digit (1) from the dividend after 5, then repeat: 51 / 977

Let's proceed to step 2:
977 can be fit into 51 0 times, resulting in a remainder of 51.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 51 and we're left with 51.
Fetch the next digit (5) from the dividend, attach it to 51 and continue: 515 / 977

On to step 3:
The number 977 fits into 515 0 times, leaving a remainder of 515.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 515, we get 515.
Include the next digit (7) from the dividend after 515, then repeat: 5157 / 977

Moving on to step 4:
5157 divided by 977 is 5 with a remainder of 272.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Subtract 4885 from 5157 to get 272.
Take the next digit (8) from the dividend and append it to 272, then repeat: 2728 / 977

Step 5:
If we divide 2728 by 977, we get 2 and a remainder of 774.
Record the quotient 2 as the next digit in the result. 
Result so far: 52.0
If we subtract 1954 from 2728, we get 774.
Take the next digit (4) from the dividend and append it to 774, then repeat: 7744 / 977

Advancing to step 6:
If we divide 7744 by 977, we get 7 and a remainder of 905.
The number 7 becomes the next digit in our result. 
Result so far: 527.0
Subtract 6839 from 7744 to get 905.
Fetch the next digit (1) from the dividend, attach it to 905 and continue: 9051 / 977

Moving on to step 7:
977 can be fit into 9051 9 times, resulting in a remainder of 258.
Write down 9 as next digit of the result. 
Result so far: 5279.0
If we take 8793 away from 9051, we end up with 258.
Include the next digit (5) from the dividend after 258, then repeat: 2585 / 977

Moving on to step 8:
If we divide 2585 by 977, we get 2 and a remainder of 631.
The number 2 becomes the next digit in our result. 
Result so far: 52792.0
The remainder is 631 after subtracting 1954 from 2585.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6310, and continue the process.

Step 9:
The number 977 fits into 6310 6 times, leaving a remainder of 448.
Record the quotient 6 as the next digit in the result. 
Result so far: 52792.6
Deduct 5862 from 6310 and we're left with 448.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4480, and continue the process.

Moving on to step 10:
The number 977 fits into 4480 4 times, leaving a remainder of 572.
Use 4 as the next digit of our solution. 
Result so far: 52792.64
If we take 3908 away from 4480, we end up with 572.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5720, and continue the process.

Let's proceed to step 11:
5720 divided by 977 is 5 with a remainder of 835.
Put 5 as the next digit of the answer. 
Result so far: 52792.645
If we subtract 4885 from 5720, we get 835.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8350, and continue the process.

Going ahead to step 12:
977 can be fit into 8350 8 times, resulting in a remainder of 534.
Record the quotient 8 as the next digit in the result. 
Result so far: 52792.6458
Subtracting 7816 from 8350 leaves us with 534.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5340, and continue the process.

Advancing to step 13:
977 can be fit into 5340 5 times, resulting in a remainder of 455.
Write down 5 as next digit of the result. 
Result so far: 52792.64585
Subtracting 4885 from 5340 leaves us with 455.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4550, and continue the process.

Advancing to step 14:
4550 divided by 977 is 4 with a remainder of 642.
The next digit of our result is 4. 
Result so far: 52792.645854
If we subtract 3908 from 4550, we get 642.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6420, and continue the process.

Advancing to step 15:
977 can be fit into 6420 6 times, resulting in a remainder of 558.
Record the quotient 6 as the next digit in the result. 
Result so far: 52792.6458546
Subtract 5862 from 6420 to get 558.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5580, and continue the process.

Moving on to step 16:
When dividing 5580 by 977, we get 5 with a remainder of 695.
The next digit of our result is 5. 
Result so far: 52792.64585465
If we subtract 4885 from 5580, we get 695.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6950, and continue the process.

The final result is 52792.64585465 with a remainder of 6.95e-07.
