We look at the division of 10520 by 76 
Our goal is to divide 10520 by 76.

Advancing to step 1:
76 goes into 1 0 times with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Append the next digit (0) from the dividend to 1 and continue with: 10 / 76

Advancing to step 2:
The number 76 fits into 10 0 times, leaving a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 10 leaves us with 10.
Take the next digit (5) from the dividend and append it to 10, then repeat: 105 / 76

Advancing to step 3:
76 can be fit into 105 1 times, resulting in a remainder of 29.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 76 from 105, we get 29.
Fetch the next digit (2) from the dividend, attach it to 29 and continue: 292 / 76

Let's proceed to step 4:
If we divide 292 by 76, we get 3 and a remainder of 64.
Put 3 as the next digit of the answer. 
Result so far: 13.0
The remainder is 64 after subtracting 228 from 292.
Append the next digit (0) from the dividend to 64 and continue with: 640 / 76

Let's proceed to step 5:
76 can be fit into 640 8 times, resulting in a remainder of 32.
The number 8 becomes the next digit in our result. 
Result so far: 138.0
If we subtract 608 from 640, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 6:
76 goes into 320 4 times with a remainder of 16.
Record the quotient 4 as the next digit in the result. 
Result so far: 138.4
Subtracting 304 from 320 leaves us 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.

Going ahead to step 7:
The number 76 fits into 160 2 times, leaving a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 138.42
Subtracting 152 from 160 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 8:
80 divided by 76 is 1 with a remainder of 4.
The next digit of our result is 1. 
Result so far: 138.421
Deduct 76 from 80 and we're left with 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 9:
If we divide 40 by 76, we get 0 and a remainder of 40.
The next digit of our result is 0. 
Result so far: 138.421
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.

Let's proceed to step 10:
When dividing 400 by 76, we get 5 with a remainder of 20.
The number 5 becomes the next digit in our result. 
Result so far: 138.42105
Subtracting 380 from 400 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.

Moving on to step 11:
The number 76 fits into 200 2 times, leaving a remainder of 48.
Write down 2 as next digit of the result. 
Result so far: 138.421052
Deduct 152 from 200 and we're left 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.

Step 12:
76 goes into 480 6 times with a remainder of 24.
Put 6 as the next digit of the answer. 
Result so far: 138.4210526
The remainder is 24 after subtracting 456 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 13:
When dividing 240 by 76, we get 3 with a remainder of 12.
The next digit of our result is 3. 
Result so far: 138.42105263
If we take 228 away from 240, we end up 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.

Our division results in 138.42105263 with a remaining 1.2e-08.
