Let's divide 637139 by 23
We're looking to find how many times 23 goes into 637139.

Let's proceed to step 1:
If we divide 6 by 23, we get 0 and a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Include the next digit (3) from the dividend after 6, then repeat: 63 / 23

Going ahead to step 2:
23 can be fit into 63 2 times, resulting in a remainder of 17.
Write down 2 as next digit of the result. 
Result so far: 2.0
The remainder is 17 after subtracting 46 from 63.
Append the next digit (7) from the dividend to 17 and continue with: 177 / 23

Step 3:
23 goes into 177 7 times with a remainder of 16.
Use 7 as the next digit of our solution. 
Result so far: 27.0
If we take 161 away from 177, we end up with 16.
Bring next digit (1) of the dividend behind the 16 and repeat the process: 161 / 23

Let's proceed to step 4:
23 goes into 161 7 times with a remainder of 0.
Put 7 as the next digit of the answer. 
Result so far: 277.0
Subtract 161 from 161 to get 0.
Append the next digit (3) from the dividend to 0 and continue with: 3 / 23

Step 5:
23 goes into 3 0 times with a remainder of 3.
The next digit of our result is 0. 
Result so far: 2770.0
Subtract 0 from 3 to get 3.
Take the next digit (9) from the dividend and append it to 3, then repeat: 39 / 23

Step 6:
23 goes into 39 1 times with a remainder of 16.
The next digit of our result is 1. 
Result so far: 27701.0
Deduct 23 from 39 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 7:
23 can be fit into 160 6 times, resulting in a remainder of 22.
Put 6 as the next digit of the answer. 
Result so far: 27701.6
Subtracting 138 from 160 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 8:
The number 23 fits into 220 9 times, leaving a remainder of 13.
Write down 9 as next digit of the result. 
Result so far: 27701.69
If we subtract 207 from 220, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Advancing to step 9:
23 can be fit into 130 5 times, resulting in a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 27701.695
Subtracting 115 from 130 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 10:
23 can be fit into 150 6 times, resulting in a remainder of 12.
Write down 6 as next digit of the result. 
Result so far: 27701.6956
If we subtract 138 from 150, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 11:
23 can be fit into 120 5 times, resulting in a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 27701.69565
If we take 115 away from 120, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 12:
When dividing 50 by 23, we get 2 with a remainder of 4.
The number 2 becomes the next digit in our result. 
Result so far: 27701.695652
Subtract 46 from 50 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 13:
The number 23 fits into 40 1 times, leaving a remainder of 17.
The next digit of our result is 1. 
Result so far: 27701.6956521
Deduct 23 from 40 and we're left with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 14:
23 can be fit into 170 7 times, resulting in a remainder of 9.
The number 7 becomes the next digit in our result. 
Result so far: 27701.69565217
The remainder is 9 after subtracting 161 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Our division results in 27701.69565217 with a remaining 9e-09.
