We look at the division of 20713071 by 161 
We're looking to find how many times 161 goes into 20713071.

Step 1:
2 divided by 161 is 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Fetch the next digit (0) from the dividend, attach it to 2 and continue: 20 / 161

On to step 2:
161 can be fit into 20 0 times, resulting in a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 20, we end up with 20.
Grab the next digit (7) from the dividend, add it to 20, then carry on: 207 / 161

On to step 3:
207 divided by 161 is 1 with a remainder of 46.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 161 from 207 and we're left with 46.
Append the next digit (1) from the dividend to 46 and continue with: 461 / 161

Let's proceed to step 4:
The number 161 fits into 461 2 times, leaving a remainder of 139.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
Subtract 322 from 461 to get 139.
Include the next digit (3) from the dividend after 139, then repeat: 1393 / 161

Step 5:
1393 divided by 161 is 8 with a remainder of 105.
Put 8 as the next digit of the answer. 
Result so far: 128.0
The remainder is 105 after subtracting 1288 from 1393.
Grab the next digit (0) from the dividend, add it to 105, then carry on: 1050 / 161

Moving on to step 6:
When dividing 1050 by 161, we get 6 with a remainder of 84.
Record the quotient 6 as the next digit in the result. 
Result so far: 1286.0
Subtracting 966 from 1050 leaves us with 84.
Bring next digit (7) of the dividend behind the 84 and repeat the process: 847 / 161

On to step 7:
161 can be fit into 847 5 times, resulting in a remainder of 42.
Use 5 as the next digit of our solution. 
Result so far: 12865.0
The remainder is 42 after subtracting 805 from 847.
Append the next digit (1) from the dividend to 42 and continue with: 421 / 161

On to step 8:
When dividing 421 by 161, we get 2 with a remainder of 99.
The number 2 becomes the next digit in our result. 
Result so far: 128652.0
The remainder is 99 after subtracting 322 from 421.
Since there are no more digits in the dividend, we add a zero to the remainder making it 990, and continue the process.

On to step 9:
If we divide 990 by 161, we get 6 and a remainder of 24.
The number 6 becomes the next digit in our result. 
Result so far: 128652.6
Deduct 966 from 990 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 10:
When dividing 240 by 161, we get 1 with a remainder of 79.
Write down 1 as next digit of the result. 
Result so far: 128652.61
Subtracting 161 from 240 leaves us with 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

On to step 11:
161 goes into 790 4 times with a remainder of 146.
Use 4 as the next digit of our solution. 
Result so far: 128652.614
If we take 644 away from 790, we end up with 146.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

Let's proceed to step 12:
161 can be fit into 1460 9 times, resulting in a remainder of 11.
Record the quotient 9 as the next digit in the result. 
Result so far: 128652.6149
Subtract 1449 from 1460 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 13:
When dividing 110 by 161, we get 0 with a remainder of 110.
Record the quotient 0 as the next digit in the result. 
Result so far: 128652.6149
Subtracting 0 from 110 leaves us with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Moving on to step 14:
161 goes into 1100 6 times with a remainder of 134.
Record the quotient 6 as the next digit in the result. 
Result so far: 128652.614906
Deduct 966 from 1100 and we're left with 134.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

Let's proceed to step 15:
The number 161 fits into 1340 8 times, leaving a remainder of 52.
Record the quotient 8 as the next digit in the result. 
Result so far: 128652.6149068
Subtracting 1288 from 1340 leaves us with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

On to step 16:
If we divide 520 by 161, we get 3 and a remainder of 37.
The number 3 becomes the next digit in our result. 
Result so far: 128652.61490683
If we take 483 away from 520, we end up with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Our division results in 128652.61490683 with a remaining 3.7e-08.
