We divide 39504780 by 770
Our goal is to divide 39504780 by 770.

Step 1:
770 can be fit into 3 0 times, resulting in a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 770

Advancing to step 2:
If we divide 39 by 770, we get 0 and a remainder of 39.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 39 leaves us with 39.
Grab the next digit (5) from the dividend, add it to 39, then carry on: 395 / 770

Moving on to step 3:
If we divide 395 by 770, we get 0 and a remainder of 395.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 395 and we're left with 395.
Fetch the next digit (0) from the dividend, attach it to 395 and continue: 3950 / 770

Moving on to step 4:
770 can be fit into 3950 5 times, resulting in a remainder of 100.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
The remainder is 100 after subtracting 3850 from 3950.
Bring next digit (4) of the dividend behind the 100 and repeat the process: 1004 / 770

Let's proceed to step 5:
770 can be fit into 1004 1 times, resulting in a remainder of 234.
Put 1 as the next digit of the answer. 
Result so far: 51.0
Deduct 770 from 1004 and we're left with 234.
Grab the next digit (7) from the dividend, add it to 234, then carry on: 2347 / 770

Step 6:
When dividing 2347 by 770, we get 3 with a remainder of 37.
Write down 3 as next digit of the result. 
Result so far: 513.0
If we subtract 2310 from 2347, we get 37.
Include the next digit (8) from the dividend after 37, then repeat: 378 / 770

On to step 7:
When dividing 378 by 770, we get 0 with a remainder of 378.
Put 0 as the next digit of the answer. 
Result so far: 5130.0
The remainder is 378 after subtracting 0 from 378.
Grab the next digit (0) from the dividend, add it to 378, then carry on: 3780 / 770

Moving on to step 8:
When dividing 3780 by 770, we get 4 with a remainder of 700.
Put 4 as the next digit of the answer. 
Result so far: 51304.0
Subtract 3080 from 3780 to get 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7000, and continue the process.

On to step 9:
770 can be fit into 7000 9 times, resulting in a remainder of 70.
Use 9 as the next digit of our solution. 
Result so far: 51304.9
Deduct 6930 from 7000 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Advancing to step 10:
The number 770 fits into 700 0 times, leaving a remainder of 700.
Put 0 as the next digit of the answer. 
Result so far: 51304.9
The remainder is 700 after subtracting 0 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7000, and continue the process.

Moving on to step 11:
7000 divided by 770 is 9 with a remainder of 70.
Use 9 as the next digit of our solution. 
Result so far: 51304.909
Subtract 6930 from 7000 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 12:
770 goes into 700 0 times with a remainder of 700.
Put 0 as the next digit of the answer. 
Result so far: 51304.909
If we subtract 0 from 700, we get 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7000, and continue the process.

Let's proceed to step 13:
7000 divided by 770 is 9 with a remainder of 70.
The number 9 becomes the next digit in our result. 
Result so far: 51304.90909
Deduct 6930 from 7000 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Advancing to step 14:
770 goes into 700 0 times with a remainder of 700.
Put 0 as the next digit of the answer. 
Result so far: 51304.90909
Deduct 0 from 700 and we're left with 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7000, and continue the process.

On to step 15:
If we divide 7000 by 770, we get 9 and a remainder of 70.
The next digit of our result is 9. 
Result so far: 51304.9090909
Subtracting 6930 from 7000 leaves us with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Step 16:
770 goes into 700 0 times with a remainder of 700.
The number 0 becomes the next digit in our result. 
Result so far: 51304.9090909
If we subtract 0 from 700, we get 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7000, and continue the process.

The final result is 51304.9090909 with a remainder of 7e-07.
