78549329 ÷ 161 
Our goal is to divide 78549329 by 161.

Let's proceed to step 1:
7 divided by 161 is 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 161

Let's proceed to step 2:
When dividing 78 by 161, 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 subtract 0 from 78, we get 78.
Fetch the next digit (5) from the dividend, attach it to 78 and continue: 785 / 161

On to step 3:
The number 161 fits into 785 4 times, leaving a remainder of 141.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we take 644 away from 785, we end up with 141.
Bring next digit (4) of the dividend behind the 141 and repeat the process: 1414 / 161

Let's proceed to step 4:
161 goes into 1414 8 times with a remainder of 126.
Use 8 as the next digit of our solution. 
Result so far: 48.0
Deduct 1288 from 1414 and we're left with 126.
Append the next digit (9) from the dividend to 126 and continue with: 1269 / 161

On to step 5:
The number 161 fits into 1269 7 times, leaving a remainder of 142.
Write down 7 as next digit of the result. 
Result so far: 487.0
If we subtract 1127 from 1269, we get 142.
Append the next digit (3) from the dividend to 142 and continue with: 1423 / 161

Advancing to step 6:
The number 161 fits into 1423 8 times, leaving a remainder of 135.
Write down 8 as next digit of the result. 
Result so far: 4878.0
Deduct 1288 from 1423 and we're left with 135.
Grab the next digit (2) from the dividend, add it to 135, then carry on: 1352 / 161

Moving on to step 7:
1352 divided by 161 is 8 with a remainder of 64.
The next digit of our result is 8. 
Result so far: 48788.0
If we subtract 1288 from 1352, we get 64.
Include the next digit (9) from the dividend after 64, then repeat: 649 / 161

Let's proceed to step 8:
The number 161 fits into 649 4 times, leaving a remainder of 5.
Use 4 as the next digit of our solution. 
Result so far: 487884.0
Subtract 644 from 649 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 9:
161 can be fit into 50 0 times, resulting in a remainder of 50.
Write down 0 as next digit of the result. 
Result so far: 487884.0
Subtract 0 from 50 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 10:
161 can be fit into 500 3 times, resulting in a remainder of 17.
Use 3 as the next digit of our solution. 
Result so far: 487884.03
The remainder is 17 after subtracting 483 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Going ahead to step 11:
If we divide 170 by 161, we get 1 and a remainder of 9.
Record the quotient 1 as the next digit in the result. 
Result so far: 487884.031
Deduct 161 from 170 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 12:
If we divide 90 by 161, we get 0 and a remainder of 90.
The next digit of our result is 0. 
Result so far: 487884.031
If we take 0 away from 90, 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.

Let's proceed to step 13:
900 divided by 161 is 5 with a remainder of 95.
The number 5 becomes the next digit in our result. 
Result so far: 487884.03105
Subtract 805 from 900 to get 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

Let's proceed to step 14:
161 can be fit into 950 5 times, resulting in a remainder of 145.
Record the quotient 5 as the next digit in the result. 
Result so far: 487884.031055
The remainder is 145 after subtracting 805 from 950.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

After the division, we end up with 487884.031055 and a remainder of 1.45e-05.
