We're dividing 75780978 by 161 
We're looking to find how many times 161 goes into 75780978.

Advancing to step 1:
161 can be fit into 7 0 times, resulting in a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Take the next digit (5) from the dividend and append it to 7, then repeat: 75 / 161

Step 2:
When dividing 75 by 161, we get 0 with a remainder of 75.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 75 leaves us with 75.
Bring next digit (7) of the dividend behind the 75 and repeat the process: 757 / 161

Advancing to step 3:
161 can be fit into 757 4 times, resulting in a remainder of 113.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we subtract 644 from 757, we get 113.
Take the next digit (8) from the dividend and append it to 113, then repeat: 1138 / 161

On to step 4:
161 can be fit into 1138 7 times, resulting in a remainder of 11.
The number 7 becomes the next digit in our result. 
Result so far: 47.0
Subtract 1127 from 1138 to get 11.
Append the next digit (0) from the dividend to 11 and continue with: 110 / 161

Let's proceed to step 5:
110 divided by 161 is 0 with a remainder of 110.
Put 0 as the next digit of the answer. 
Result so far: 470.0
The remainder is 110 after subtracting 0 from 110.
Append the next digit (9) from the dividend to 110 and continue with: 1109 / 161

On to step 6:
161 can be fit into 1109 6 times, resulting in a remainder of 143.
Use 6 as the next digit of our solution. 
Result so far: 4706.0
If we subtract 966 from 1109, we get 143.
Include the next digit (7) from the dividend after 143, then repeat: 1437 / 161

Step 7:
If we divide 1437 by 161, we get 8 and a remainder of 149.
Record the quotient 8 as the next digit in the result. 
Result so far: 47068.0
If we take 1288 away from 1437, we end up with 149.
Bring next digit (8) of the dividend behind the 149 and repeat the process: 1498 / 161

Step 8:
When dividing 1498 by 161, we get 9 with a remainder of 49.
The number 9 becomes the next digit in our result. 
Result so far: 470689.0
Subtract 1449 from 1498 to get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Step 9:
The number 161 fits into 490 3 times, leaving a remainder of 7.
Record the quotient 3 as the next digit in the result. 
Result so far: 470689.3
Subtract 483 from 490 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 10:
The number 161 fits into 70 0 times, leaving a remainder of 70.
Put 0 as the next digit of the answer. 
Result so far: 470689.3
The remainder is 70 after subtracting 0 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Advancing to step 11:
When dividing 700 by 161, we get 4 with a remainder of 56.
Record the quotient 4 as the next digit in the result. 
Result so far: 470689.304
Subtracting 644 from 700 leaves us with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Let's proceed to step 12:
161 goes into 560 3 times with a remainder of 77.
Use 3 as the next digit of our solution. 
Result so far: 470689.3043
Subtracting 483 from 560 leaves us with 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

On to step 13:
770 divided by 161 is 4 with a remainder of 126.
Put 4 as the next digit of the answer. 
Result so far: 470689.30434
Subtract 644 from 770 to get 126.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

Let's proceed to step 14:
When dividing 1260 by 161, we get 7 with a remainder of 133.
Write down 7 as next digit of the result. 
Result so far: 470689.304347
If we subtract 1127 from 1260, we get 133.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1330, and continue the process.

On to step 15:
The number 161 fits into 1330 8 times, leaving a remainder of 42.
Write down 8 as next digit of the result. 
Result so far: 470689.3043478
Subtracting 1288 from 1330 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 16:
If we divide 420 by 161, we get 2 and a remainder of 98.
Write down 2 as next digit of the result. 
Result so far: 470689.30434782
Deduct 322 from 420 and we're left with 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

The final result is 470689.30434782 with a remainder of 9.8e-08.
