We're dividing 76428776 by 578 
Our goal is to divide 76428776 by 578.

On to step 1:
578 goes into 7 0 times with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Take the next digit (6) from the dividend and append it to 7, then repeat: 76 / 578

Step 2:
When dividing 76 by 578, we get 0 with a remainder of 76.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 76 to get 76.
Append the next digit (4) from the dividend to 76 and continue with: 764 / 578

Let's proceed to step 3:
578 can be fit into 764 1 times, resulting in a remainder of 186.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 578 from 764, we get 186.
Fetch the next digit (2) from the dividend, attach it to 186 and continue: 1862 / 578

Moving on to step 4:
1862 divided by 578 is 3 with a remainder of 128.
Use 3 as the next digit of our solution. 
Result so far: 13.0
Subtracting 1734 from 1862 leaves us with 128.
Append the next digit (8) from the dividend to 128 and continue with: 1288 / 578

Advancing to step 5:
578 goes into 1288 2 times with a remainder of 132.
The next digit of our result is 2. 
Result so far: 132.0
Deduct 1156 from 1288 and we're left with 132.
Fetch the next digit (7) from the dividend, attach it to 132 and continue: 1327 / 578

Moving on to step 6:
578 goes into 1327 2 times with a remainder of 171.
Put 2 as the next digit of the answer. 
Result so far: 1322.0
The remainder is 171 after subtracting 1156 from 1327.
Grab the next digit (7) from the dividend, add it to 171, then carry on: 1717 / 578

Let's proceed to step 7:
The number 578 fits into 1717 2 times, leaving a remainder of 561.
Use 2 as the next digit of our solution. 
Result so far: 13222.0
The remainder is 561 after subtracting 1156 from 1717.
Fetch the next digit (6) from the dividend, attach it to 561 and continue: 5616 / 578

Let's proceed to step 8:
When dividing 5616 by 578, we get 9 with a remainder of 414.
Put 9 as the next digit of the answer. 
Result so far: 132229.0
Subtracting 5202 from 5616 leaves us with 414.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4140, and continue the process.

Step 9:
The number 578 fits into 4140 7 times, leaving a remainder of 94.
Record the quotient 7 as the next digit in the result. 
Result so far: 132229.7
Subtracting 4046 from 4140 leaves us with 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Let's proceed to step 10:
578 goes into 940 1 times with a remainder of 362.
The next digit of our result is 1. 
Result so far: 132229.71
Subtract 578 from 940 to get 362.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3620, and continue the process.

Step 11:
When dividing 3620 by 578, we get 6 with a remainder of 152.
Put 6 as the next digit of the answer. 
Result so far: 132229.716
If we take 3468 away from 3620, we end up with 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Moving on to step 12:
1520 divided by 578 is 2 with a remainder of 364.
The number 2 becomes the next digit in our result. 
Result so far: 132229.7162
Subtract 1156 from 1520 to get 364.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3640, and continue the process.

Moving on to step 13:
When dividing 3640 by 578, we get 6 with a remainder of 172.
Put 6 as the next digit of the answer. 
Result so far: 132229.71626
Deduct 3468 from 3640 and we're left with 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

On to step 14:
1720 divided by 578 is 2 with a remainder of 564.
The next digit of our result is 2. 
Result so far: 132229.716262
Subtracting 1156 from 1720 leaves us with 564.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5640, and continue the process.

Step 15:
If we divide 5640 by 578, we get 9 and a remainder of 438.
Use 9 as the next digit of our solution. 
Result so far: 132229.7162629
The remainder is 438 after subtracting 5202 from 5640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4380, and continue the process.

Advancing to step 16:
If we divide 4380 by 578, we get 7 and a remainder of 334.
Use 7 as the next digit of our solution. 
Result so far: 132229.71626297
Subtract 4046 from 4380 to get 334.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3340, and continue the process.

The final result is 132229.71626297 with a remainder of 3.34e-07.
