Let's divide 78605153 by 571
Our goal is to divide 78605153 by 571.

Going ahead to step 1:
The number 571 fits into 7 0 times, leaving a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Bring next digit (8) of the dividend behind the 7 and repeat the process: 78 / 571

On to step 2:
78 divided by 571 is 0 with a remainder of 78.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 78, we end up with 78.
Fetch the next digit (6) from the dividend, attach it to 78 and continue: 786 / 571

Advancing to step 3:
When dividing 786 by 571, we get 1 with a remainder of 215.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 571 from 786 to get 215.
Grab the next digit (0) from the dividend, add it to 215, then carry on: 2150 / 571

Moving on to step 4:
571 goes into 2150 3 times with a remainder of 437.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
Subtract 1713 from 2150 to get 437.
Bring next digit (5) of the dividend behind the 437 and repeat the process: 4375 / 571

Moving on to step 5:
If we divide 4375 by 571, we get 7 and a remainder of 378.
Put 7 as the next digit of the answer. 
Result so far: 137.0
If we take 3997 away from 4375, we end up with 378.
Append the next digit (1) from the dividend to 378 and continue with: 3781 / 571

Advancing to step 6:
571 goes into 3781 6 times with a remainder of 355.
The number 6 becomes the next digit in our result. 
Result so far: 1376.0
If we subtract 3426 from 3781, we get 355.
Take the next digit (5) from the dividend and append it to 355, then repeat: 3555 / 571

On to step 7:
If we divide 3555 by 571, we get 6 and a remainder of 129.
Record the quotient 6 as the next digit in the result. 
Result so far: 13766.0
If we take 3426 away from 3555, we end up with 129.
Append the next digit (3) from the dividend to 129 and continue with: 1293 / 571

Let's proceed to step 8:
If we divide 1293 by 571, we get 2 and a remainder of 151.
Record the quotient 2 as the next digit in the result. 
Result so far: 137662.0
If we take 1142 away from 1293, we end up with 151.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1510, and continue the process.

Going ahead to step 9:
The number 571 fits into 1510 2 times, leaving a remainder of 368.
Use 2 as the next digit of our solution. 
Result so far: 137662.2
Subtracting 1142 from 1510 leaves us with 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

On to step 10:
571 goes into 3680 6 times with a remainder of 254.
Record the quotient 6 as the next digit in the result. 
Result so far: 137662.26
Deduct 3426 from 3680 and we're left with 254.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2540, and continue the process.

On to step 11:
The number 571 fits into 2540 4 times, leaving a remainder of 256.
Write down 4 as next digit of the result. 
Result so far: 137662.264
Deduct 2284 from 2540 and we're left with 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Going ahead to step 12:
571 can be fit into 2560 4 times, resulting in a remainder of 276.
Use 4 as the next digit of our solution. 
Result so far: 137662.2644
Subtract 2284 from 2560 to get 276.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2760, and continue the process.

After the division, we end up with 137662.2644 and a remainder of 0.00276.
