We're dividing 77452157 by 989 
We're looking to find how many times 989 goes into 77452157.

Moving on to step 1:
If we divide 7 by 989, we get 0 and a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Append the next digit (7) from the dividend to 7 and continue with: 77 / 989

Moving on to step 2:
989 goes into 77 0 times with a remainder of 77.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 77 leaves us with 77.
Include the next digit (4) from the dividend after 77, then repeat: 774 / 989

Going ahead to step 3:
989 can be fit into 774 0 times, resulting in a remainder of 774.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 774 after subtracting 0 from 774.
Grab the next digit (5) from the dividend, add it to 774, then carry on: 7745 / 989

Advancing to step 4:
The number 989 fits into 7745 7 times, leaving a remainder of 822.
Write down 7 as next digit of the result. 
Result so far: 7.0
Subtract 6923 from 7745 to get 822.
Append the next digit (2) from the dividend to 822 and continue with: 8222 / 989

Moving on to step 5:
When dividing 8222 by 989, we get 8 with a remainder of 310.
Use 8 as the next digit of our solution. 
Result so far: 78.0
If we take 7912 away from 8222, we end up with 310.
Include the next digit (1) from the dividend after 310, then repeat: 3101 / 989

Step 6:
When dividing 3101 by 989, we get 3 with a remainder of 134.
The number 3 becomes the next digit in our result. 
Result so far: 783.0
Deduct 2967 from 3101 and we're left with 134.
Take the next digit (5) from the dividend and append it to 134, then repeat: 1345 / 989

On to step 7:
1345 divided by 989 is 1 with a remainder of 356.
The number 1 becomes the next digit in our result. 
Result so far: 7831.0
Subtract 989 from 1345 to get 356.
Fetch the next digit (7) from the dividend, attach it to 356 and continue: 3567 / 989

On to step 8:
When dividing 3567 by 989, we get 3 with a remainder of 600.
Write down 3 as next digit of the result. 
Result so far: 78313.0
The remainder is 600 after subtracting 2967 from 3567.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Advancing to step 9:
If we divide 6000 by 989, we get 6 and a remainder of 66.
The number 6 becomes the next digit in our result. 
Result so far: 78313.6
Deduct 5934 from 6000 and we're left with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Let's proceed to step 10:
989 can be fit into 660 0 times, resulting in a remainder of 660.
Record the quotient 0 as the next digit in the result. 
Result so far: 78313.6
If we subtract 0 from 660, we get 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6600, and continue the process.

Advancing to step 11:
The number 989 fits into 6600 6 times, leaving a remainder of 666.
Use 6 as the next digit of our solution. 
Result so far: 78313.606
If we subtract 5934 from 6600, we get 666.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6660, and continue the process.

Going ahead to step 12:
6660 divided by 989 is 6 with a remainder of 726.
Put 6 as the next digit of the answer. 
Result so far: 78313.6066
Subtracting 5934 from 6660 leaves us with 726.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7260, and continue the process.

The final result is 78313.6066 with a remainder of 0.00726.
