We look at the division of 7989424 by 578 
We're looking to find how many times 578 goes into 7989424.

Step 1:
When dividing 7 by 578, we get 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Bring next digit (9) of the dividend behind the 7 and repeat the process: 79 / 578

Moving on to step 2:
If we divide 79 by 578, we get 0 and a remainder of 79.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 79 leaves us with 79.
Bring next digit (8) of the dividend behind the 79 and repeat the process: 798 / 578

Step 3:
578 can be fit into 798 1 times, resulting in a remainder of 220.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 578 from 798 leaves us with 220.
Fetch the next digit (9) from the dividend, attach it to 220 and continue: 2209 / 578

Advancing to step 4:
When dividing 2209 by 578, we get 3 with a remainder of 475.
Use 3 as the next digit of our solution. 
Result so far: 13.0
Subtract 1734 from 2209 to get 475.
Append the next digit (4) from the dividend to 475 and continue with: 4754 / 578

On to step 5:
If we divide 4754 by 578, we get 8 and a remainder of 130.
Put 8 as the next digit of the answer. 
Result so far: 138.0
The remainder is 130 after subtracting 4624 from 4754.
Grab the next digit (2) from the dividend, add it to 130, then carry on: 1302 / 578

Going ahead to step 6:
When dividing 1302 by 578, we get 2 with a remainder of 146.
The next digit of our result is 2. 
Result so far: 1382.0
Deduct 1156 from 1302 and we're left with 146.
Grab the next digit (4) from the dividend, add it to 146, then carry on: 1464 / 578

On to step 7:
When dividing 1464 by 578, we get 2 with a remainder of 308.
Put 2 as the next digit of the answer. 
Result so far: 13822.0
Subtract 1156 from 1464 to get 308.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3080, and continue the process.

Advancing to step 8:
3080 divided by 578 is 5 with a remainder of 190.
Record the quotient 5 as the next digit in the result. 
Result so far: 13822.5
Deduct 2890 from 3080 and we're left with 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Going ahead to step 9:
578 can be fit into 1900 3 times, resulting in a remainder of 166.
Put 3 as the next digit of the answer. 
Result so far: 13822.53
If we take 1734 away from 1900, we end up with 166.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1660, and continue the process.

Let's proceed to step 10:
1660 divided by 578 is 2 with a remainder of 504.
The next digit of our result is 2. 
Result so far: 13822.532
If we subtract 1156 from 1660, we get 504.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5040, and continue the process.

Let's proceed to step 11:
The number 578 fits into 5040 8 times, leaving a remainder of 416.
Record the quotient 8 as the next digit in the result. 
Result so far: 13822.5328
Subtracting 4624 from 5040 leaves us with 416.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

Advancing to step 12:
4160 divided by 578 is 7 with a remainder of 114.
The next digit of our result is 7. 
Result so far: 13822.53287
The remainder is 114 after subtracting 4046 from 4160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

Advancing to step 13:
578 can be fit into 1140 1 times, resulting in a remainder of 562.
The next digit of our result is 1. 
Result so far: 13822.532871
Subtracting 578 from 1140 leaves us with 562.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5620, and continue the process.

Going ahead to step 14:
5620 divided by 578 is 9 with a remainder of 418.
The number 9 becomes the next digit in our result. 
Result so far: 13822.5328719
Deduct 5202 from 5620 and we're left with 418.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4180, and continue the process.

Moving on to step 15:
4180 divided by 578 is 7 with a remainder of 134.
The number 7 becomes the next digit in our result. 
Result so far: 13822.53287197
If we subtract 4046 from 4180, we get 134.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

Our division results in 13822.53287197 with a remaining 1.34e-07.
