71604170 divided by 161 
Our goal is to divide 71604170 by 161.

Going ahead to step 1:
161 goes into 7 0 times with 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 (1) from the dividend and append it to 7, then repeat: 71 / 161

Step 2:
161 can be fit into 71 0 times, resulting in a remainder of 71.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 71 to get 71.
Include the next digit (6) from the dividend after 71, then repeat: 716 / 161

Going ahead to step 3:
161 goes into 716 4 times with a remainder of 72.
The next digit of our result is 4. 
Result so far: 4.0
If we take 644 away from 716, we end up with 72.
Append the next digit (0) from the dividend to 72 and continue with: 720 / 161

Advancing to step 4:
The number 161 fits into 720 4 times, leaving a remainder of 76.
The number 4 becomes the next digit in our result. 
Result so far: 44.0
The remainder is 76 after subtracting 644 from 720.
Bring next digit (4) of the dividend behind the 76 and repeat the process: 764 / 161

On to step 5:
When dividing 764 by 161, we get 4 with a remainder of 120.
Write down 4 as next digit of the result. 
Result so far: 444.0
The remainder is 120 after subtracting 644 from 764.
Fetch the next digit (1) from the dividend, attach it to 120 and continue: 1201 / 161

Step 6:
If we divide 1201 by 161, we get 7 and a remainder of 74.
Use 7 as the next digit of our solution. 
Result so far: 4447.0
Subtract 1127 from 1201 to get 74.
Append the next digit (7) from the dividend to 74 and continue with: 747 / 161

Step 7:
161 goes into 747 4 times with a remainder of 103.
The next digit of our result is 4. 
Result so far: 44474.0
Subtracting 644 from 747 leaves us with 103.
Fetch the next digit (0) from the dividend, attach it to 103 and continue: 1030 / 161

On to step 8:
161 goes into 1030 6 times with a remainder of 64.
Put 6 as the next digit of the answer. 
Result so far: 444746.0
If we subtract 966 from 1030, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

On to step 9:
The number 161 fits into 640 3 times, leaving a remainder of 157.
Use 3 as the next digit of our solution. 
Result so far: 444746.3
The remainder is 157 after subtracting 483 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1570, and continue the process.

Step 10:
If we divide 1570 by 161, we get 9 and a remainder of 121.
Record the quotient 9 as the next digit in the result. 
Result so far: 444746.39
The remainder is 121 after subtracting 1449 from 1570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1210, and continue the process.

Moving on to step 11:
The number 161 fits into 1210 7 times, leaving a remainder of 83.
The number 7 becomes the next digit in our result. 
Result so far: 444746.397
Subtract 1127 from 1210 to get 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Let's proceed to step 12:
161 goes into 830 5 times with a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 444746.3975
Deduct 805 from 830 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Advancing to step 13:
If we divide 250 by 161, we get 1 and a remainder of 89.
The next digit of our result is 1. 
Result so far: 444746.39751
If we take 161 away from 250, we end up with 89.
Since there are no more digits in the dividend, we add a zero to the remainder making it 890, and continue the process.

On to step 14:
When dividing 890 by 161, we get 5 with a remainder of 85.
The number 5 becomes the next digit in our result. 
Result so far: 444746.397515
Subtracting 805 from 890 leaves us with 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Going ahead to step 15:
850 divided by 161 is 5 with a remainder of 45.
Put 5 as the next digit of the answer. 
Result so far: 444746.3975155
If we subtract 805 from 850, we get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

The final result is 444746.3975155 with a remainder of 4.5e-07.
