We look at the division of 76749520 by 550 
Let's see how many times 550 fits into 76749520.

Advancing to step 1:
When dividing 7 by 550, we get 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Grab the next digit (6) from the dividend, add it to 7, then carry on: 76 / 550

On to step 2:
When dividing 76 by 550, we get 0 with a remainder of 76.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 76, we end up with 76.
Take the next digit (7) from the dividend and append it to 76, then repeat: 767 / 550

Advancing to step 3:
767 divided by 550 is 1 with a remainder of 217.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 550 from 767 to get 217.
Fetch the next digit (4) from the dividend, attach it to 217 and continue: 2174 / 550

Going ahead to step 4:
If we divide 2174 by 550, we get 3 and a remainder of 524.
Use 3 as the next digit of our solution. 
Result so far: 13.0
If we subtract 1650 from 2174, we get 524.
Bring next digit (9) of the dividend behind the 524 and repeat the process: 5249 / 550

Moving on to step 5:
5249 divided by 550 is 9 with a remainder of 299.
Record the quotient 9 as the next digit in the result. 
Result so far: 139.0
Subtracting 4950 from 5249 leaves us with 299.
Append the next digit (5) from the dividend to 299 and continue with: 2995 / 550

Moving on to step 6:
The number 550 fits into 2995 5 times, leaving a remainder of 245.
The number 5 becomes the next digit in our result. 
Result so far: 1395.0
Subtracting 2750 from 2995 leaves us with 245.
Include the next digit (2) from the dividend after 245, then repeat: 2452 / 550

On to step 7:
550 can be fit into 2452 4 times, resulting in a remainder of 252.
Use 4 as the next digit of our solution. 
Result so far: 13954.0
Deduct 2200 from 2452 and we're left with 252.
Bring next digit (0) of the dividend behind the 252 and repeat the process: 2520 / 550

Moving on to step 8:
550 can be fit into 2520 4 times, resulting in a remainder of 320.
Put 4 as the next digit of the answer. 
Result so far: 139544.0
Subtract 2200 from 2520 to get 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Going ahead to step 9:
If we divide 3200 by 550, we get 5 and a remainder of 450.
Write down 5 as next digit of the result. 
Result so far: 139544.5
The remainder is 450 after subtracting 2750 from 3200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

Advancing to step 10:
If we divide 4500 by 550, we get 8 and a remainder of 100.
The next digit of our result is 8. 
Result so far: 139544.58
If we subtract 4400 from 4500, we get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Step 11:
550 can be fit into 1000 1 times, resulting in a remainder of 450.
Use 1 as the next digit of our solution. 
Result so far: 139544.581
If we subtract 550 from 1000, we get 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

Moving on to step 12:
550 can be fit into 4500 8 times, resulting in a remainder of 100.
Put 8 as the next digit of the answer. 
Result so far: 139544.5818
Subtracting 4400 from 4500 leaves us with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

On to step 13:
1000 divided by 550 is 1 with a remainder of 450.
The number 1 becomes the next digit in our result. 
Result so far: 139544.58181
The remainder is 450 after subtracting 550 from 1000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

Advancing to step 14:
550 can be fit into 4500 8 times, resulting in a remainder of 100.
Put 8 as the next digit of the answer. 
Result so far: 139544.581818
If we subtract 4400 from 4500, we get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

On to step 15:
When dividing 1000 by 550, we get 1 with a remainder of 450.
Write down 1 as next digit of the result. 
Result so far: 139544.5818181
Subtract 550 from 1000 to get 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

Step 16:
4500 divided by 550 is 8 with a remainder of 100.
Use 8 as the next digit of our solution. 
Result so far: 139544.58181818
If we take 4400 away from 4500, we end up with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

The final outcome is 139544.58181818, with a leftover of 1e-07.
