We look at the division of 23640688 by 139 
We want to figure out the number of times 23640688 can be divided by 139.

Let's proceed to step 1:
When dividing 2 by 139, we get 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Bring next digit (3) of the dividend behind the 2 and repeat the process: 23 / 139

Let's proceed to step 2:
If we divide 23 by 139, we get 0 and a remainder of 23.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 23 leaves us with 23.
Grab the next digit (6) from the dividend, add it to 23, then carry on: 236 / 139

Moving on to step 3:
139 can be fit into 236 1 times, resulting in a remainder of 97.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 139 from 236 and we're left with 97.
Take the next digit (4) from the dividend and append it to 97, then repeat: 974 / 139

Step 4:
When dividing 974 by 139, we get 7 with a remainder of 1.
The number 7 becomes the next digit in our result. 
Result so far: 17.0
Subtracting 973 from 974 leaves us with 1.
Take the next digit (0) from the dividend and append it to 1, then repeat: 10 / 139

Moving on to step 5:
The number 139 fits into 10 0 times, leaving a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 170.0
If we take 0 away from 10, we end up with 10.
Take the next digit (6) from the dividend and append it to 10, then repeat: 106 / 139

On to step 6:
139 goes into 106 0 times with a remainder of 106.
The next digit of our result is 0. 
Result so far: 1700.0
Deduct 0 from 106 and we're left with 106.
Bring next digit (8) of the dividend behind the 106 and repeat the process: 1068 / 139

Moving on to step 7:
139 goes into 1068 7 times with a remainder of 95.
The next digit of our result is 7. 
Result so far: 17007.0
The remainder is 95 after subtracting 973 from 1068.
Append the next digit (8) from the dividend to 95 and continue with: 958 / 139

On to step 8:
139 can be fit into 958 6 times, resulting in a remainder of 124.
The number 6 becomes the next digit in our result. 
Result so far: 170076.0
Deduct 834 from 958 and we're left with 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

On to step 9:
The number 139 fits into 1240 8 times, leaving a remainder of 128.
The number 8 becomes the next digit in our result. 
Result so far: 170076.8
If we take 1112 away from 1240, we end up with 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Moving on to step 10:
If we divide 1280 by 139, we get 9 and a remainder of 29.
Use 9 as the next digit of our solution. 
Result so far: 170076.89
If we take 1251 away from 1280, we end up with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Let's proceed to step 11:
If we divide 290 by 139, we get 2 and a remainder of 12.
Record the quotient 2 as the next digit in the result. 
Result so far: 170076.892
The remainder is 12 after subtracting 278 from 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 12:
When dividing 120 by 139, we get 0 with a remainder of 120.
Use 0 as the next digit of our solution. 
Result so far: 170076.892
Deduct 0 from 120 and we're left with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

On to step 13:
1200 divided by 139 is 8 with a remainder of 88.
Put 8 as the next digit of the answer. 
Result so far: 170076.89208
Deduct 1112 from 1200 and we're left with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Step 14:
139 can be fit into 880 6 times, resulting in a remainder of 46.
Put 6 as the next digit of the answer. 
Result so far: 170076.892086
The remainder is 46 after subtracting 834 from 880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Moving on to step 15:
139 goes into 460 3 times with a remainder of 43.
The number 3 becomes the next digit in our result. 
Result so far: 170076.8920863
Deduct 417 from 460 and we're left with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Going ahead to step 16:
The number 139 fits into 430 3 times, leaving a remainder of 13.
Write down 3 as next digit of the result. 
Result so far: 170076.89208633
Deduct 417 from 430 and we're left with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

The final result is 170076.89208633 with a remainder of 1.3e-08.
