43012520 ÷ 778 
Our goal is to divide 43012520 by 778.

Advancing to step 1:
The number 778 fits into 4 0 times, leaving a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Fetch the next digit (3) from the dividend, attach it to 4 and continue: 43 / 778

On to step 2:
If we divide 43 by 778, we get 0 and a remainder of 43.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 43, we get 43.
Bring next digit (0) of the dividend behind the 43 and repeat the process: 430 / 778

Advancing to step 3:
When dividing 430 by 778, we get 0 with a remainder of 430.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 430 leaves us with 430.
Fetch the next digit (1) from the dividend, attach it to 430 and continue: 4301 / 778

Moving on to step 4:
778 can be fit into 4301 5 times, resulting in a remainder of 411.
Put 5 as the next digit of the answer. 
Result so far: 5.0
If we subtract 3890 from 4301, we get 411.
Bring next digit (2) of the dividend behind the 411 and repeat the process: 4112 / 778

On to step 5:
4112 divided by 778 is 5 with a remainder of 222.
Use 5 as the next digit of our solution. 
Result so far: 55.0
Deduct 3890 from 4112 and we're left with 222.
Include the next digit (5) from the dividend after 222, then repeat: 2225 / 778

Let's proceed to step 6:
778 goes into 2225 2 times with a remainder of 669.
Write down 2 as next digit of the result. 
Result so far: 552.0
If we take 1556 away from 2225, we end up with 669.
Include the next digit (2) from the dividend after 669, then repeat: 6692 / 778

Going ahead to step 7:
6692 divided by 778 is 8 with a remainder of 468.
The next digit of our result is 8. 
Result so far: 5528.0
Subtract 6224 from 6692 to get 468.
Include the next digit (0) from the dividend after 468, then repeat: 4680 / 778

Moving on to step 8:
4680 divided by 778 is 6 with a remainder of 12.
The number 6 becomes the next digit in our result. 
Result so far: 55286.0
Subtracting 4668 from 4680 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 9:
If we divide 120 by 778, we get 0 and a remainder of 120.
The number 0 becomes the next digit in our result. 
Result so far: 55286.0
Subtract 0 from 120 to get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Step 10:
When dividing 1200 by 778, we get 1 with a remainder of 422.
Use 1 as the next digit of our solution. 
Result so far: 55286.01
Subtracting 778 from 1200 leaves us with 422.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4220, and continue the process.

Going ahead to step 11:
778 goes into 4220 5 times with a remainder of 330.
Record the quotient 5 as the next digit in the result. 
Result so far: 55286.015
Deduct 3890 from 4220 and we're left with 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

Step 12:
778 goes into 3300 4 times with a remainder of 188.
The next digit of our result is 4. 
Result so far: 55286.0154
Subtracting 3112 from 3300 leaves us with 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

Going ahead to step 13:
If we divide 1880 by 778, we get 2 and a remainder of 324.
Use 2 as the next digit of our solution. 
Result so far: 55286.01542
The remainder is 324 after subtracting 1556 from 1880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3240, and continue the process.

On to step 14:
778 can be fit into 3240 4 times, resulting in a remainder of 128.
The number 4 becomes the next digit in our result. 
Result so far: 55286.015424
Subtract 3112 from 3240 to get 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Step 15:
1280 divided by 778 is 1 with a remainder of 502.
The next digit of our result is 1. 
Result so far: 55286.0154241
If we subtract 778 from 1280, we get 502.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5020, and continue the process.

Going ahead to step 16:
778 can be fit into 5020 6 times, resulting in a remainder of 352.
Use 6 as the next digit of our solution. 
Result so far: 55286.01542416
Subtract 4668 from 5020 to get 352.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

After the division, we end up with 55286.01542416 and a remainder of 3.52e-07.
