Let's divide 77545111 by 437
We're looking to find how many times 437 goes into 77545111.

Going ahead to step 1:
The number 437 fits into 7 0 times, leaving a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Bring next digit (7) of the dividend behind the 7 and repeat the process: 77 / 437

Going ahead to step 2:
The number 437 fits into 77 0 times, leaving a remainder of 77.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 77, we end up with 77.
Include the next digit (5) from the dividend after 77, then repeat: 775 / 437

On to step 3:
437 goes into 775 1 times with a remainder of 338.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 437 from 775 to get 338.
Take the next digit (4) from the dividend and append it to 338, then repeat: 3384 / 437

Advancing to step 4:
437 can be fit into 3384 7 times, resulting in a remainder of 325.
Write down 7 as next digit of the result. 
Result so far: 17.0
The remainder is 325 after subtracting 3059 from 3384.
Grab the next digit (5) from the dividend, add it to 325, then carry on: 3255 / 437

On to step 5:
The number 437 fits into 3255 7 times, leaving a remainder of 196.
The next digit of our result is 7. 
Result so far: 177.0
Subtracting 3059 from 3255 leaves us with 196.
Grab the next digit (1) from the dividend, add it to 196, then carry on: 1961 / 437

Going ahead to step 6:
1961 divided by 437 is 4 with a remainder of 213.
The next digit of our result is 4. 
Result so far: 1774.0
If we take 1748 away from 1961, we end up with 213.
Bring next digit (1) of the dividend behind the 213 and repeat the process: 2131 / 437

Step 7:
437 can be fit into 2131 4 times, resulting in a remainder of 383.
Record the quotient 4 as the next digit in the result. 
Result so far: 17744.0
Deduct 1748 from 2131 and we're left with 383.
Grab the next digit (1) from the dividend, add it to 383, then carry on: 3831 / 437

Going ahead to step 8:
3831 divided by 437 is 8 with a remainder of 335.
The number 8 becomes the next digit in our result. 
Result so far: 177448.0
If we take 3496 away from 3831, we end up with 335.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3350, and continue the process.

Moving on to step 9:
The number 437 fits into 3350 7 times, leaving a remainder of 291.
The next digit of our result is 7. 
Result so far: 177448.7
Deduct 3059 from 3350 and we're left with 291.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2910, and continue the process.

Step 10:
2910 divided by 437 is 6 with a remainder of 288.
Put 6 as the next digit of the answer. 
Result so far: 177448.76
Subtracting 2622 from 2910 leaves us with 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

On to step 11:
The number 437 fits into 2880 6 times, leaving a remainder of 258.
The number 6 becomes the next digit in our result. 
Result so far: 177448.766
Subtracting 2622 from 2880 leaves us with 258.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2580, and continue the process.

Our division results in 177448.766 with a remaining 0.0258.
