We divide 78065989 by 122
Our goal is to divide 78065989 by 122.

Moving on to step 1:
The number 122 fits into 7 0 times, leaving a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 122

Advancing to step 2:
The number 122 fits into 78 0 times, leaving a remainder of 78.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 78 to get 78.
Take the next digit (0) from the dividend and append it to 78, then repeat: 780 / 122

Moving on to step 3:
122 can be fit into 780 6 times, resulting in a remainder of 48.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
The remainder is 48 after subtracting 732 from 780.
Fetch the next digit (6) from the dividend, attach it to 48 and continue: 486 / 122

Moving on to step 4:
486 divided by 122 is 3 with a remainder of 120.
Write down 3 as next digit of the result. 
Result so far: 63.0
Subtract 366 from 486 to get 120.
Grab the next digit (5) from the dividend, add it to 120, then carry on: 1205 / 122

Going ahead to step 5:
When dividing 1205 by 122, we get 9 with a remainder of 107.
Record the quotient 9 as the next digit in the result. 
Result so far: 639.0
Deduct 1098 from 1205 and we're left with 107.
Fetch the next digit (9) from the dividend, attach it to 107 and continue: 1079 / 122

Let's proceed to step 6:
122 goes into 1079 8 times with a remainder of 103.
The number 8 becomes the next digit in our result. 
Result so far: 6398.0
Deduct 976 from 1079 and we're left with 103.
Include the next digit (8) from the dividend after 103, then repeat: 1038 / 122

Moving on to step 7:
1038 divided by 122 is 8 with a remainder of 62.
Write down 8 as next digit of the result. 
Result so far: 63988.0
Subtracting 976 from 1038 leaves us with 62.
Bring next digit (9) of the dividend behind the 62 and repeat the process: 629 / 122

On to step 8:
If we divide 629 by 122, we get 5 and a remainder of 19.
Put 5 as the next digit of the answer. 
Result so far: 639885.0
If we subtract 610 from 629, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

On to step 9:
When dividing 190 by 122, we get 1 with a remainder of 68.
Put 1 as the next digit of the answer. 
Result so far: 639885.1
Subtract 122 from 190 to get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Let's proceed to step 10:
When dividing 680 by 122, we get 5 with a remainder of 70.
The number 5 becomes the next digit in our result. 
Result so far: 639885.15
Deduct 610 from 680 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Step 11:
When dividing 700 by 122, we get 5 with a remainder of 90.
Record the quotient 5 as the next digit in the result. 
Result so far: 639885.155
If we take 610 away from 700, we end up with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

After the division, we end up with 639885.155 and a remainder of 0.009.
