7929954 ÷ 138 
Our goal is to divide 7929954 by 138.

On to step 1:
When dividing 7 by 138, we get 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Take the next digit (9) from the dividend and append it to 7, then repeat: 79 / 138

Step 2:
138 can be fit into 79 0 times, resulting in a remainder of 79.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 79 and we're left with 79.
Bring next digit (2) of the dividend behind the 79 and repeat the process: 792 / 138

Moving on to step 3:
When dividing 792 by 138, we get 5 with a remainder of 102.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
If we take 690 away from 792, we end up with 102.
Fetch the next digit (9) from the dividend, attach it to 102 and continue: 1029 / 138

Let's proceed to step 4:
If we divide 1029 by 138, we get 7 and a remainder of 63.
Put 7 as the next digit of the answer. 
Result so far: 57.0
Subtract 966 from 1029 to get 63.
Include the next digit (9) from the dividend after 63, then repeat: 639 / 138

Moving on to step 5:
The number 138 fits into 639 4 times, leaving a remainder of 87.
The number 4 becomes the next digit in our result. 
Result so far: 574.0
The remainder is 87 after subtracting 552 from 639.
Include the next digit (5) from the dividend after 87, then repeat: 875 / 138

On to step 6:
The number 138 fits into 875 6 times, leaving a remainder of 47.
The next digit of our result is 6. 
Result so far: 5746.0
The remainder is 47 after subtracting 828 from 875.
Include the next digit (4) from the dividend after 47, then repeat: 474 / 138

Moving on to step 7:
When dividing 474 by 138, we get 3 with a remainder of 60.
Use 3 as the next digit of our solution. 
Result so far: 57463.0
The remainder is 60 after subtracting 414 from 474.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 8:
When dividing 600 by 138, we get 4 with a remainder of 48.
The number 4 becomes the next digit in our result. 
Result so far: 57463.4
Subtracting 552 from 600 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Going ahead to step 9:
138 goes into 480 3 times with a remainder of 66.
Put 3 as the next digit of the answer. 
Result so far: 57463.43
The remainder is 66 after subtracting 414 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Going ahead to step 10:
138 goes into 660 4 times with a remainder of 108.
Put 4 as the next digit of the answer. 
Result so far: 57463.434
Subtract 552 from 660 to get 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Moving on to step 11:
1080 divided by 138 is 7 with a remainder of 114.
The number 7 becomes the next digit in our result. 
Result so far: 57463.4347
The remainder is 114 after subtracting 966 from 1080.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

Step 12:
138 goes into 1140 8 times with a remainder of 36.
Write down 8 as next digit of the result. 
Result so far: 57463.43478
Deduct 1104 from 1140 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 13:
360 divided by 138 is 2 with a remainder of 84.
Record the quotient 2 as the next digit in the result. 
Result so far: 57463.434782
Subtract 276 from 360 to get 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Going ahead to step 14:
When dividing 840 by 138, we get 6 with a remainder of 12.
Record the quotient 6 as the next digit in the result. 
Result so far: 57463.4347826
Subtracting 828 from 840 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 15:
138 goes into 120 0 times with a remainder of 120.
Put 0 as the next digit of the answer. 
Result so far: 57463.4347826
If we take 0 away from 120, we end up 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.

The final result is 57463.4347826 with a remainder of 1.2e-07.
