We look at the division of 66567734 by 161 
Let's see how many times 161 fits into 66567734.

Moving on to step 1:
6 divided by 161 is 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 161

Let's proceed to step 2:
The number 161 fits into 66 0 times, leaving a remainder of 66.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 66, we end up with 66.
Take the next digit (5) from the dividend and append it to 66, then repeat: 665 / 161

Let's proceed to step 3:
If we divide 665 by 161, we get 4 and a remainder of 21.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Deduct 644 from 665 and we're left with 21.
Append the next digit (6) from the dividend to 21 and continue with: 216 / 161

Moving on to step 4:
161 goes into 216 1 times with a remainder of 55.
The next digit of our result is 1. 
Result so far: 41.0
If we subtract 161 from 216, we get 55.
Bring next digit (7) of the dividend behind the 55 and repeat the process: 557 / 161

Step 5:
If we divide 557 by 161, we get 3 and a remainder of 74.
The next digit of our result is 3. 
Result so far: 413.0
Subtracting 483 from 557 leaves us with 74.
Append the next digit (7) from the dividend to 74 and continue with: 747 / 161

Moving on to step 6:
If we divide 747 by 161, we get 4 and a remainder of 103.
The number 4 becomes the next digit in our result. 
Result so far: 4134.0
Subtract 644 from 747 to get 103.
Grab the next digit (3) from the dividend, add it to 103, then carry on: 1033 / 161

On to step 7:
The number 161 fits into 1033 6 times, leaving a remainder of 67.
Put 6 as the next digit of the answer. 
Result so far: 41346.0
If we subtract 966 from 1033, we get 67.
Include the next digit (4) from the dividend after 67, then repeat: 674 / 161

Going ahead to step 8:
The number 161 fits into 674 4 times, leaving a remainder of 30.
The next digit of our result is 4. 
Result so far: 413464.0
Subtracting 644 from 674 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 9:
The number 161 fits into 300 1 times, leaving a remainder of 139.
Put 1 as the next digit of the answer. 
Result so far: 413464.1
The remainder is 139 after subtracting 161 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1390, and continue the process.

Going ahead to step 10:
The number 161 fits into 1390 8 times, leaving a remainder of 102.
Use 8 as the next digit of our solution. 
Result so far: 413464.18
If we take 1288 away from 1390, we end up with 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

On to step 11:
If we divide 1020 by 161, we get 6 and a remainder of 54.
Put 6 as the next digit of the answer. 
Result so far: 413464.186
If we take 966 away from 1020, we end up with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Moving on to step 12:
When dividing 540 by 161, we get 3 with a remainder of 57.
Record the quotient 3 as the next digit in the result. 
Result so far: 413464.1863
If we subtract 483 from 540, we get 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Step 13:
161 goes into 570 3 times with a remainder of 87.
Write down 3 as next digit of the result. 
Result so far: 413464.18633
Deduct 483 from 570 and we're left with 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

The final outcome is 413464.18633, with a leftover of 8.7e-05.
