10259020 divided by 138 
Our goal is to divide 10259020 by 138.

Advancing to step 1:
1 divided by 138 is 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Bring next digit (0) of the dividend behind the 1 and repeat the process: 10 / 138

Going ahead to step 2:
138 goes into 10 0 times with a remainder of 10.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 10 after subtracting 0 from 10.
Take the next digit (2) from the dividend and append it to 10, then repeat: 102 / 138

Let's proceed to step 3:
138 can be fit into 102 0 times, resulting in a remainder of 102.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 102, we end up with 102.
Take the next digit (5) from the dividend and append it to 102, then repeat: 1025 / 138

Step 4:
138 can be fit into 1025 7 times, resulting in a remainder of 59.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Deduct 966 from 1025 and we're left with 59.
Bring next digit (9) of the dividend behind the 59 and repeat the process: 599 / 138

On to step 5:
If we divide 599 by 138, we get 4 and a remainder of 47.
Record the quotient 4 as the next digit in the result. 
Result so far: 74.0
The remainder is 47 after subtracting 552 from 599.
Take the next digit (0) from the dividend and append it to 47, then repeat: 470 / 138

Step 6:
138 goes into 470 3 times with a remainder of 56.
The next digit of our result is 3. 
Result so far: 743.0
Subtracting 414 from 470 leaves us with 56.
Bring next digit (2) of the dividend behind the 56 and repeat the process: 562 / 138

Step 7:
138 goes into 562 4 times with a remainder of 10.
Use 4 as the next digit of our solution. 
Result so far: 7434.0
If we subtract 552 from 562, we get 10.
Append the next digit (0) from the dividend to 10 and continue with: 100 / 138

Let's proceed to step 8:
138 goes into 100 0 times with a remainder of 100.
The number 0 becomes the next digit in our result. 
Result so far: 74340.0
The remainder is 100 after subtracting 0 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Let's proceed to step 9:
138 goes into 1000 7 times with a remainder of 34.
Use 7 as the next digit of our solution. 
Result so far: 74340.7
Subtract 966 from 1000 to get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 10:
138 can be fit into 340 2 times, resulting in a remainder of 64.
Use 2 as the next digit of our solution. 
Result so far: 74340.72
The remainder is 64 after subtracting 276 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Going ahead to step 11:
The number 138 fits into 640 4 times, leaving a remainder of 88.
The number 4 becomes the next digit in our result. 
Result so far: 74340.724
The remainder is 88 after subtracting 552 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Let's proceed to step 12:
880 divided by 138 is 6 with a remainder of 52.
Put 6 as the next digit of the answer. 
Result so far: 74340.7246
Deduct 828 from 880 and we're left 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.

Advancing to step 13:
138 goes into 520 3 times with a remainder of 106.
Record the quotient 3 as the next digit in the result. 
Result so far: 74340.72463
Deduct 414 from 520 and we're left with 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Going ahead to step 14:
138 can be fit into 1060 7 times, resulting in a remainder of 94.
Record the quotient 7 as the next digit in the result. 
Result so far: 74340.724637
Subtracting 966 from 1060 leaves us with 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Step 15:
If we divide 940 by 138, we get 6 and a remainder of 112.
Record the quotient 6 as the next digit in the result. 
Result so far: 74340.7246376
Deduct 828 from 940 and we're left with 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

On to step 16:
The number 138 fits into 1120 8 times, leaving a remainder of 16.
Record the quotient 8 as the next digit in the result. 
Result so far: 74340.72463768
If we take 1104 away from 1120, we end up 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.

In conclusion, the division gives 74340.72463768 with a balance of 1.6e-08.
