We look at the division of 75660143 by 138 
We want to figure out the number of times 75660143 can be divided by 138.

On to step 1:
When dividing 7 by 138, we get 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Take the next digit (5) from the dividend and append it to 7, then repeat: 75 / 138

Going ahead to step 2:
138 goes into 75 0 times with a remainder of 75.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 75, we get 75.
Include the next digit (6) from the dividend after 75, then repeat: 756 / 138

Let's proceed to step 3:
756 divided by 138 is 5 with a remainder of 66.
The next digit of our result is 5. 
Result so far: 5.0
The remainder is 66 after subtracting 690 from 756.
Take the next digit (6) from the dividend and append it to 66, then repeat: 666 / 138

Moving on to step 4:
The number 138 fits into 666 4 times, leaving a remainder of 114.
Record the quotient 4 as the next digit in the result. 
Result so far: 54.0
The remainder is 114 after subtracting 552 from 666.
Append the next digit (0) from the dividend to 114 and continue with: 1140 / 138

Advancing to step 5:
The number 138 fits into 1140 8 times, leaving a remainder of 36.
Record the quotient 8 as the next digit in the result. 
Result so far: 548.0
Deduct 1104 from 1140 and we're left with 36.
Include the next digit (1) from the dividend after 36, then repeat: 361 / 138

Advancing to step 6:
If we divide 361 by 138, we get 2 and a remainder of 85.
The number 2 becomes the next digit in our result. 
Result so far: 5482.0
Subtract 276 from 361 to get 85.
Grab the next digit (4) from the dividend, add it to 85, then carry on: 854 / 138

Let's proceed to step 7:
854 divided by 138 is 6 with a remainder of 26.
Use 6 as the next digit of our solution. 
Result so far: 54826.0
The remainder is 26 after subtracting 828 from 854.
Bring next digit (3) of the dividend behind the 26 and repeat the process: 263 / 138

Advancing to step 8:
When dividing 263 by 138, we get 1 with a remainder of 125.
The number 1 becomes the next digit in our result. 
Result so far: 548261.0
The remainder is 125 after subtracting 138 from 263.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Step 9:
138 goes into 1250 9 times with a remainder of 8.
Write down 9 as next digit of the result. 
Result so far: 548261.9
The remainder is 8 after subtracting 1242 from 1250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 10:
If we divide 80 by 138, we get 0 and a remainder of 80.
Record the quotient 0 as the next digit in the result. 
Result so far: 548261.9
Deduct 0 from 80 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

On to step 11:
138 can be fit into 800 5 times, resulting in a remainder of 110.
Record the quotient 5 as the next digit in the result. 
Result so far: 548261.905
Subtracting 690 from 800 leaves us with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Going ahead to step 12:
When dividing 1100 by 138, we get 7 with a remainder of 134.
The next digit of our result is 7. 
Result so far: 548261.9057
If we subtract 966 from 1100, we get 134.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

Let's proceed to step 13:
138 goes into 1340 9 times with a remainder of 98.
The number 9 becomes the next digit in our result. 
Result so far: 548261.90579
Subtract 1242 from 1340 to get 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

On to step 14:
138 can be fit into 980 7 times, resulting in a remainder of 14.
The number 7 becomes the next digit in our result. 
Result so far: 548261.905797
Subtract 966 from 980 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 15:
The number 138 fits into 140 1 times, leaving a remainder of 2.
The next digit of our result is 1. 
Result so far: 548261.9057971
If we subtract 138 from 140, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 16:
The number 138 fits into 20 0 times, leaving a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 548261.9057971
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

In conclusion, the division gives 548261.9057971 with a balance of 2e-08.
