We're dividing 78876914 by 571 
We want to divide 78876914 by 571.

Let's proceed to step 1:
7 divided by 571 is 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 571

Let's proceed to step 2:
When dividing 78 by 571, we get 0 with a remainder of 78.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 78 to get 78.
Fetch the next digit (8) from the dividend, attach it to 78 and continue: 788 / 571

Advancing to step 3:
If we divide 788 by 571, we get 1 and a remainder of 217.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 571 from 788 leaves us with 217.
Grab the next digit (7) from the dividend, add it to 217, then carry on: 2177 / 571

Let's proceed to step 4:
571 goes into 2177 3 times with a remainder of 464.
The next digit of our result is 3. 
Result so far: 13.0
Subtract 1713 from 2177 to get 464.
Bring next digit (6) of the dividend behind the 464 and repeat the process: 4646 / 571

Moving on to step 5:
571 goes into 4646 8 times with a remainder of 78.
The number 8 becomes the next digit in our result. 
Result so far: 138.0
If we take 4568 away from 4646, we end up with 78.
Take the next digit (9) from the dividend and append it to 78, then repeat: 789 / 571

Moving on to step 6:
571 can be fit into 789 1 times, resulting in a remainder of 218.
Record the quotient 1 as the next digit in the result. 
Result so far: 1381.0
Subtracting 571 from 789 leaves us with 218.
Bring next digit (1) of the dividend behind the 218 and repeat the process: 2181 / 571

Let's proceed to step 7:
The number 571 fits into 2181 3 times, leaving a remainder of 468.
Put 3 as the next digit of the answer. 
Result so far: 13813.0
Deduct 1713 from 2181 and we're left with 468.
Include the next digit (4) from the dividend after 468, then repeat: 4684 / 571

On to step 8:
571 can be fit into 4684 8 times, resulting in a remainder of 116.
Use 8 as the next digit of our solution. 
Result so far: 138138.0
The remainder is 116 after subtracting 4568 from 4684.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Advancing to step 9:
571 goes into 1160 2 times with a remainder of 18.
Put 2 as the next digit of the answer. 
Result so far: 138138.2
Subtracting 1142 from 1160 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 10:
571 goes into 180 0 times with a remainder of 180.
Put 0 as the next digit of the answer. 
Result so far: 138138.2
The remainder is 180 after subtracting 0 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Step 11:
The number 571 fits into 1800 3 times, leaving a remainder of 87.
Put 3 as the next digit of the answer. 
Result so far: 138138.203
The remainder is 87 after subtracting 1713 from 1800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

Going ahead to step 12:
571 can be fit into 870 1 times, resulting in a remainder of 299.
The number 1 becomes the next digit in our result. 
Result so far: 138138.2031
The remainder is 299 after subtracting 571 from 870.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2990, and continue the process.

Let's proceed to step 13:
571 can be fit into 2990 5 times, resulting in a remainder of 135.
Put 5 as the next digit of the answer. 
Result so far: 138138.20315
Subtracting 2855 from 2990 leaves us with 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

Going ahead to step 14:
571 can be fit into 1350 2 times, resulting in a remainder of 208.
The next digit of our result is 2. 
Result so far: 138138.203152
Deduct 1142 from 1350 and we're left with 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Going ahead to step 15:
2080 divided by 571 is 3 with a remainder of 367.
Put 3 as the next digit of the answer. 
Result so far: 138138.2031523
Deduct 1713 from 2080 and we're left with 367.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3670, and continue the process.

Let's proceed to step 16:
The number 571 fits into 3670 6 times, leaving a remainder of 244.
The next digit of our result is 6. 
Result so far: 138138.20315236
If we take 3426 away from 3670, we end up with 244.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2440, and continue the process.

In conclusion, the division gives 138138.20315236 with a balance of 2.44e-07.
