We look at the division of 12223708 by 138 
We want to divide 12223708 by 138.

Step 1:
If we divide 1 by 138, we get 0 and a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 138

Moving on to step 2:
The number 138 fits into 12 0 times, leaving a remainder of 12.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 12, we get 12.
Take the next digit (2) from the dividend and append it to 12, then repeat: 122 / 138

Step 3:
138 goes into 122 0 times with a remainder of 122.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 122 leaves us with 122.
Fetch the next digit (2) from the dividend, attach it to 122 and continue: 1222 / 138

Moving on to step 4:
If we divide 1222 by 138, we get 8 and a remainder of 118.
Write down 8 as next digit of the result. 
Result so far: 8.0
Subtract 1104 from 1222 to get 118.
Append the next digit (3) from the dividend to 118 and continue with: 1183 / 138

Going ahead to step 5:
138 can be fit into 1183 8 times, resulting in a remainder of 79.
The number 8 becomes the next digit in our result. 
Result so far: 88.0
Deduct 1104 from 1183 and we're left with 79.
Take the next digit (7) from the dividend and append it to 79, then repeat: 797 / 138

On to step 6:
If we divide 797 by 138, we get 5 and a remainder of 107.
Use 5 as the next digit of our solution. 
Result so far: 885.0
Deduct 690 from 797 and we're left with 107.
Include the next digit (0) from the dividend after 107, then repeat: 1070 / 138

Going ahead to step 7:
The number 138 fits into 1070 7 times, leaving a remainder of 104.
The next digit of our result is 7. 
Result so far: 8857.0
Subtracting 966 from 1070 leaves us with 104.
Grab the next digit (8) from the dividend, add it to 104, then carry on: 1048 / 138

Step 8:
138 can be fit into 1048 7 times, resulting in a remainder of 82.
The number 7 becomes the next digit in our result. 
Result so far: 88577.0
If we subtract 966 from 1048, we get 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Going ahead to step 9:
138 goes into 820 5 times with a remainder of 130.
Use 5 as the next digit of our solution. 
Result so far: 88577.5
Subtract 690 from 820 to get 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Going ahead to step 10:
The number 138 fits into 1300 9 times, leaving a remainder of 58.
Record the quotient 9 as the next digit in the result. 
Result so far: 88577.59
Deduct 1242 from 1300 and we're left with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Let's proceed to step 11:
580 divided by 138 is 4 with a remainder of 28.
The number 4 becomes the next digit in our result. 
Result so far: 88577.594
The remainder is 28 after subtracting 552 from 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 12:
280 divided by 138 is 2 with a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 88577.5942
If we subtract 276 from 280, we 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.

On to step 13:
If we divide 40 by 138, we get 0 and a remainder of 40.
The next digit of our result is 0. 
Result so far: 88577.5942
Subtract 0 from 40 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 14:
138 can be fit into 400 2 times, resulting in a remainder of 124.
Put 2 as the next digit of the answer. 
Result so far: 88577.594202
If we subtract 276 from 400, we get 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

Going ahead to step 15:
When dividing 1240 by 138, we get 8 with a remainder of 136.
Write down 8 as next digit of the result. 
Result so far: 88577.5942028
Deduct 1104 from 1240 and we're left with 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

On to step 16:
The number 138 fits into 1360 9 times, leaving a remainder of 118.
Put 9 as the next digit of the answer. 
Result so far: 88577.59420289
Subtract 1242 from 1360 to get 118.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

Our division results in 88577.59420289 with a remaining 1.18e-07.
