We look at the division of 51584904 by 770 
We want to figure out the number of times 51584904 can be divided by 770.

On to step 1:
If we divide 5 by 770, we get 0 and a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Take the next digit (1) from the dividend and append it to 5, then repeat: 51 / 770

Step 2:
If we divide 51 by 770, we get 0 and a remainder of 51.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 51, we get 51.
Take the next digit (5) from the dividend and append it to 51, then repeat: 515 / 770

Advancing to step 3:
If we divide 515 by 770, we get 0 and a remainder of 515.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 515 to get 515.
Include the next digit (8) from the dividend after 515, then repeat: 5158 / 770

On to step 4:
5158 divided by 770 is 6 with a remainder of 538.
Use 6 as the next digit of our solution. 
Result so far: 6.0
Subtract 4620 from 5158 to get 538.
Bring next digit (4) of the dividend behind the 538 and repeat the process: 5384 / 770

Step 5:
770 can be fit into 5384 6 times, resulting in a remainder of 764.
Use 6 as the next digit of our solution. 
Result so far: 66.0
If we take 4620 away from 5384, we end up with 764.
Take the next digit (9) from the dividend and append it to 764, then repeat: 7649 / 770

Let's proceed to step 6:
770 can be fit into 7649 9 times, resulting in a remainder of 719.
Use 9 as the next digit of our solution. 
Result so far: 669.0
If we subtract 6930 from 7649, we get 719.
Take the next digit (0) from the dividend and append it to 719, then repeat: 7190 / 770

Going ahead to step 7:
If we divide 7190 by 770, we get 9 and a remainder of 260.
The number 9 becomes the next digit in our result. 
Result so far: 6699.0
The remainder is 260 after subtracting 6930 from 7190.
Grab the next digit (4) from the dividend, add it to 260, then carry on: 2604 / 770

Going ahead to step 8:
770 can be fit into 2604 3 times, resulting in a remainder of 294.
Use 3 as the next digit of our solution. 
Result so far: 66993.0
If we subtract 2310 from 2604, we get 294.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2940, and continue the process.

Advancing to step 9:
770 can be fit into 2940 3 times, resulting in a remainder of 630.
Put 3 as the next digit of the answer. 
Result so far: 66993.3
If we subtract 2310 from 2940, we get 630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6300, and continue the process.

Let's proceed to step 10:
770 can be fit into 6300 8 times, resulting in a remainder of 140.
The next digit of our result is 8. 
Result so far: 66993.38
The remainder is 140 after subtracting 6160 from 6300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Going ahead to step 11:
770 can be fit into 1400 1 times, resulting in a remainder of 630.
Put 1 as the next digit of the answer. 
Result so far: 66993.381
If we take 770 away from 1400, we end up with 630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6300, and continue the process.

Moving on to step 12:
6300 divided by 770 is 8 with a remainder of 140.
The next digit of our result is 8. 
Result so far: 66993.3818
Deduct 6160 from 6300 and we're left with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Advancing to step 13:
If we divide 1400 by 770, we get 1 and a remainder of 630.
Use 1 as the next digit of our solution. 
Result so far: 66993.38181
Subtracting 770 from 1400 leaves us with 630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6300, and continue the process.

Let's proceed to step 14:
If we divide 6300 by 770, we get 8 and a remainder of 140.
Record the quotient 8 as the next digit in the result. 
Result so far: 66993.381818
If we take 6160 away from 6300, we end up with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Advancing to step 15:
1400 divided by 770 is 1 with a remainder of 630.
The number 1 becomes the next digit in our result. 
Result so far: 66993.3818181
Subtracting 770 from 1400 leaves us with 630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6300, and continue the process.

Step 16:
The number 770 fits into 6300 8 times, leaving a remainder of 140.
Put 8 as the next digit of the answer. 
Result so far: 66993.38181818
If we take 6160 away from 6300, we end up with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

The final result is 66993.38181818 with a remainder of 1.4e-07.
