We look at the division of 7996198 by 138 
We want to divide 7996198 by 138.

Step 1:
138 goes into 7 0 times with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Take the next digit (9) from the dividend and append it to 7, then repeat: 79 / 138

Let's proceed to step 2:
When dividing 79 by 138, we get 0 with a remainder of 79.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 79 after subtracting 0 from 79.
Take the next digit (9) from the dividend and append it to 79, then repeat: 799 / 138

Going ahead to step 3:
799 divided by 138 is 5 with a remainder of 109.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Subtract 690 from 799 to get 109.
Grab the next digit (6) from the dividend, add it to 109, then carry on: 1096 / 138

Going ahead to step 4:
1096 divided by 138 is 7 with a remainder of 130.
Record the quotient 7 as the next digit in the result. 
Result so far: 57.0
Subtract 966 from 1096 to get 130.
Grab the next digit (1) from the dividend, add it to 130, then carry on: 1301 / 138

Moving on to step 5:
138 goes into 1301 9 times with a remainder of 59.
Put 9 as the next digit of the answer. 
Result so far: 579.0
Deduct 1242 from 1301 and we're left with 59.
Include the next digit (9) from the dividend after 59, then repeat: 599 / 138

Step 6:
138 can be fit into 599 4 times, resulting in a remainder of 47.
Use 4 as the next digit of our solution. 
Result so far: 5794.0
The remainder is 47 after subtracting 552 from 599.
Bring next digit (8) of the dividend behind the 47 and repeat the process: 478 / 138

Moving on to step 7:
138 can be fit into 478 3 times, resulting in a remainder of 64.
The number 3 becomes the next digit in our result. 
Result so far: 57943.0
Subtracting 414 from 478 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Let's proceed to step 8:
640 divided by 138 is 4 with a remainder of 88.
Use 4 as the next digit of our solution. 
Result so far: 57943.4
If we take 552 away from 640, we end up 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 9:
138 can be fit into 880 6 times, resulting in a remainder of 52.
Write down 6 as next digit of the result. 
Result so far: 57943.46
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.

Moving on to step 10:
138 can be fit into 520 3 times, resulting in a remainder of 106.
The next digit of our result is 3. 
Result so far: 57943.463
If we take 414 away from 520, we end up 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.

On to step 11:
If we divide 1060 by 138, we get 7 and a remainder of 94.
The number 7 becomes the next digit in our result. 
Result so far: 57943.4637
If we subtract 966 from 1060, we get 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Going ahead to step 12:
The number 138 fits into 940 6 times, leaving a remainder of 112.
The number 6 becomes the next digit in our result. 
Result so far: 57943.46376
If we take 828 away from 940, we end up 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 13:
If we divide 1120 by 138, we get 8 and a remainder of 16.
Write down 8 as next digit of the result. 
Result so far: 57943.463768
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.

Let's proceed to step 14:
The number 138 fits into 160 1 times, leaving a remainder of 22.
Use 1 as the next digit of our solution. 
Result so far: 57943.4637681
Subtract 138 from 160 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 15:
If we divide 220 by 138, we get 1 and a remainder of 82.
Write down 1 as next digit of the result. 
Result so far: 57943.46376811
If we subtract 138 from 220, 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.

The final outcome is 57943.46376811, with a leftover of 8.2e-08.
