78084724 ÷ 989 
Our goal is to divide 78084724 by 989.

On to step 1:
989 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
Deduct 0 from 7 and we're left with 7.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 989

Step 2:
When dividing 78 by 989, we get 0 with a remainder of 78.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 78, we end up with 78.
Bring next digit (0) of the dividend behind the 78 and repeat the process: 780 / 989

Step 3:
989 goes into 780 0 times with a remainder of 780.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 780 and we're left with 780.
Take the next digit (8) from the dividend and append it to 780, then repeat: 7808 / 989

Let's proceed to step 4:
7808 divided by 989 is 7 with a remainder of 885.
Write down 7 as next digit of the result. 
Result so far: 7.0
Subtracting 6923 from 7808 leaves us with 885.
Bring next digit (4) of the dividend behind the 885 and repeat the process: 8854 / 989

Moving on to step 5:
8854 divided by 989 is 8 with a remainder of 942.
Put 8 as the next digit of the answer. 
Result so far: 78.0
Subtracting 7912 from 8854 leaves us with 942.
Fetch the next digit (7) from the dividend, attach it to 942 and continue: 9427 / 989

On to step 6:
989 can be fit into 9427 9 times, resulting in a remainder of 526.
Record the quotient 9 as the next digit in the result. 
Result so far: 789.0
Subtract 8901 from 9427 to get 526.
Append the next digit (2) from the dividend to 526 and continue with: 5262 / 989

On to step 7:
If we divide 5262 by 989, we get 5 and a remainder of 317.
Use 5 as the next digit of our solution. 
Result so far: 7895.0
Subtracting 4945 from 5262 leaves us with 317.
Bring next digit (4) of the dividend behind the 317 and repeat the process: 3174 / 989

Step 8:
When dividing 3174 by 989, we get 3 with a remainder of 207.
The number 3 becomes the next digit in our result. 
Result so far: 78953.0
Deduct 2967 from 3174 and we're left with 207.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2070, and continue the process.

On to step 9:
989 can be fit into 2070 2 times, resulting in a remainder of 92.
Write down 2 as next digit of the result. 
Result so far: 78953.2
The remainder is 92 after subtracting 1978 from 2070.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Moving on to step 10:
920 divided by 989 is 0 with a remainder of 920.
Record the quotient 0 as the next digit in the result. 
Result so far: 78953.2
Deduct 0 from 920 and we're left with 920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9200, and continue the process.

Let's proceed to step 11:
When dividing 9200 by 989, we get 9 with a remainder of 299.
The next digit of our result is 9. 
Result so far: 78953.209
Subtract 8901 from 9200 to get 299.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2990, and continue the process.

Advancing to step 12:
989 can be fit into 2990 3 times, resulting in a remainder of 23.
Write down 3 as next digit of the result. 
Result so far: 78953.2093
The remainder is 23 after subtracting 2967 from 2990.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Step 13:
If we divide 230 by 989, we get 0 and a remainder of 230.
The number 0 becomes the next digit in our result. 
Result so far: 78953.2093
Deduct 0 from 230 and we're left with 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Advancing to step 14:
989 goes into 2300 2 times with a remainder of 322.
Record the quotient 2 as the next digit in the result. 
Result so far: 78953.209302
Subtracting 1978 from 2300 leaves us with 322.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3220, and continue the process.

Going ahead to step 15:
3220 divided by 989 is 3 with a remainder of 253.
The next digit of our result is 3. 
Result so far: 78953.2093023
If we subtract 2967 from 3220, we get 253.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2530, and continue the process.

Moving on to step 16:
The number 989 fits into 2530 2 times, leaving a remainder of 552.
Use 2 as the next digit of our solution. 
Result so far: 78953.20930232
If we subtract 1978 from 2530, we get 552.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5520, and continue the process.

After the division, we end up with 78953.20930232 and a remainder of 5.52e-07.
