We're dividing 75151085 by 138 
Let's see how many times 138 fits into 75151085.

Step 1:
When dividing 7 by 138, we get 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Append the next digit (5) from the dividend to 7 and continue with: 75 / 138

Let's proceed to step 2:
138 can be fit into 75 0 times, resulting in a remainder of 75.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 75, we end up with 75.
Include the next digit (1) from the dividend after 75, then repeat: 751 / 138

Let's proceed to step 3:
When dividing 751 by 138, we get 5 with a remainder of 61.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Subtract 690 from 751 to get 61.
Grab the next digit (5) from the dividend, add it to 61, then carry on: 615 / 138

Step 4:
138 can be fit into 615 4 times, resulting in a remainder of 63.
Put 4 as the next digit of the answer. 
Result so far: 54.0
The remainder is 63 after subtracting 552 from 615.
Include the next digit (1) from the dividend after 63, then repeat: 631 / 138

Let's proceed to step 5:
138 can be fit into 631 4 times, resulting in a remainder of 79.
Put 4 as the next digit of the answer. 
Result so far: 544.0
Subtract 552 from 631 to get 79.
Include the next digit (0) from the dividend after 79, then repeat: 790 / 138

Going ahead to step 6:
138 goes into 790 5 times with a remainder of 100.
Use 5 as the next digit of our solution. 
Result so far: 5445.0
If we take 690 away from 790, we end up with 100.
Append the next digit (8) from the dividend to 100 and continue with: 1008 / 138

Moving on to step 7:
When dividing 1008 by 138, we get 7 with a remainder of 42.
Write down 7 as next digit of the result. 
Result so far: 54457.0
The remainder is 42 after subtracting 966 from 1008.
Append the next digit (5) from the dividend to 42 and continue with: 425 / 138

Moving on to step 8:
The number 138 fits into 425 3 times, leaving a remainder of 11.
The next digit of our result is 3. 
Result so far: 544573.0
If we subtract 414 from 425, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 9:
138 can be fit into 110 0 times, resulting in a remainder of 110.
The next digit of our result is 0. 
Result so far: 544573.0
Subtract 0 from 110 to get 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Step 10:
138 can be fit into 1100 7 times, resulting in a remainder of 134.
Put 7 as the next digit of the answer. 
Result so far: 544573.07
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 11:
138 can be fit into 1340 9 times, resulting in a remainder of 98.
Use 9 as the next digit of our solution. 
Result so far: 544573.079
If we subtract 1242 from 1340, we 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 12:
138 can be fit into 980 7 times, resulting in a remainder of 14.
Put 7 as the next digit of the answer. 
Result so far: 544573.0797
The remainder is 14 after subtracting 966 from 980.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 13:
138 goes into 140 1 times with a remainder of 2.
Use 1 as the next digit of our solution. 
Result so far: 544573.07971
The remainder is 2 after subtracting 138 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 14:
When dividing 20 by 138, we get 0 with a remainder of 20.
The next digit of our result is 0. 
Result so far: 544573.07971
Subtracting 0 from 20 leaves us 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.

Advancing to step 15:
138 goes into 200 1 times with a remainder of 62.
Use 1 as the next digit of our solution. 
Result so far: 544573.0797101
If we take 138 away from 200, we end up with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

On to step 16:
138 goes into 620 4 times with a remainder of 68.
The number 4 becomes the next digit in our result. 
Result so far: 544573.07971014
Deduct 552 from 620 and we're left with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

The final outcome is 544573.07971014, with a leftover of 6.8e-08.
