We look at the division of 76720454 by 538 
We're looking to find how many times 538 goes into 76720454.

Step 1:
538 goes into 7 0 times with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Bring next digit (6) of the dividend behind the 7 and repeat the process: 76 / 538

Moving on to step 2:
538 goes into 76 0 times with a remainder of 76.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 76, we get 76.
Take the next digit (7) from the dividend and append it to 76, then repeat: 767 / 538

Step 3:
538 can be fit into 767 1 times, resulting in a remainder of 229.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 538 from 767 to get 229.
Take the next digit (2) from the dividend and append it to 229, then repeat: 2292 / 538

Step 4:
If we divide 2292 by 538, we get 4 and a remainder of 140.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
If we take 2152 away from 2292, we end up with 140.
Bring next digit (0) of the dividend behind the 140 and repeat the process: 1400 / 538

Going ahead to step 5:
538 can be fit into 1400 2 times, resulting in a remainder of 324.
The number 2 becomes the next digit in our result. 
Result so far: 142.0
If we subtract 1076 from 1400, we get 324.
Fetch the next digit (4) from the dividend, attach it to 324 and continue: 3244 / 538

On to step 6:
The number 538 fits into 3244 6 times, leaving a remainder of 16.
Record the quotient 6 as the next digit in the result. 
Result so far: 1426.0
The remainder is 16 after subtracting 3228 from 3244.
Take the next digit (5) from the dividend and append it to 16, then repeat: 165 / 538

Moving on to step 7:
The number 538 fits into 165 0 times, leaving a remainder of 165.
Use 0 as the next digit of our solution. 
Result so far: 14260.0
Deduct 0 from 165 and we're left with 165.
Grab the next digit (4) from the dividend, add it to 165, then carry on: 1654 / 538

On to step 8:
538 goes into 1654 3 times with a remainder of 40.
The number 3 becomes the next digit in our result. 
Result so far: 142603.0
The remainder is 40 after subtracting 1614 from 1654.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 9:
The number 538 fits into 400 0 times, leaving a remainder of 400.
The number 0 becomes the next digit in our result. 
Result so far: 142603.0
The remainder is 400 after subtracting 0 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Advancing to step 10:
538 goes into 4000 7 times with a remainder of 234.
Write down 7 as next digit of the result. 
Result so far: 142603.07
Subtract 3766 from 4000 to get 234.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2340, and continue the process.

Going ahead to step 11:
538 can be fit into 2340 4 times, resulting in a remainder of 188.
Write down 4 as next digit of the result. 
Result so far: 142603.074
The remainder is 188 after subtracting 2152 from 2340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

Step 12:
If we divide 1880 by 538, we get 3 and a remainder of 266.
Put 3 as the next digit of the answer. 
Result so far: 142603.0743
The remainder is 266 after subtracting 1614 from 1880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2660, and continue the process.

Moving on to step 13:
2660 divided by 538 is 4 with a remainder of 508.
Put 4 as the next digit of the answer. 
Result so far: 142603.07434
Subtract 2152 from 2660 to get 508.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5080, and continue the process.

Step 14:
When dividing 5080 by 538, we get 9 with a remainder of 238.
Record the quotient 9 as the next digit in the result. 
Result so far: 142603.074349
Deduct 4842 from 5080 and we're left with 238.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2380, and continue the process.

Moving on to step 15:
The number 538 fits into 2380 4 times, leaving a remainder of 228.
Record the quotient 4 as the next digit in the result. 
Result so far: 142603.0743494
If we subtract 2152 from 2380, we get 228.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2280, and continue the process.

Moving on to step 16:
If we divide 2280 by 538, we get 4 and a remainder of 128.
Write down 4 as next digit of the result. 
Result so far: 142603.07434944
If we take 2152 away from 2280, we end up with 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

In conclusion, the division gives 142603.07434944 with a balance of 1.28e-07.
