54501438 ÷ 764 
We want to figure out the number of times 54501438 can be divided by 764.

Let's proceed to step 1:
When dividing 5 by 764, we get 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Take the next digit (4) from the dividend and append it to 5, then repeat: 54 / 764

Step 2:
764 can be fit into 54 0 times, resulting in a remainder of 54.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 54 leaves us with 54.
Append the next digit (5) from the dividend to 54 and continue with: 545 / 764

Going ahead to step 3:
When dividing 545 by 764, we get 0 with a remainder of 545.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 545 to get 545.
Append the next digit (0) from the dividend to 545 and continue with: 5450 / 764

Advancing to step 4:
When dividing 5450 by 764, we get 7 with a remainder of 102.
Put 7 as the next digit of the answer. 
Result so far: 7.0
The remainder is 102 after subtracting 5348 from 5450.
Bring next digit (1) of the dividend behind the 102 and repeat the process: 1021 / 764

Advancing to step 5:
If we divide 1021 by 764, we get 1 and a remainder of 257.
Use 1 as the next digit of our solution. 
Result so far: 71.0
Subtracting 764 from 1021 leaves us with 257.
Append the next digit (4) from the dividend to 257 and continue with: 2574 / 764

Going ahead to step 6:
764 can be fit into 2574 3 times, resulting in a remainder of 282.
Record the quotient 3 as the next digit in the result. 
Result so far: 713.0
Subtract 2292 from 2574 to get 282.
Grab the next digit (3) from the dividend, add it to 282, then carry on: 2823 / 764

On to step 7:
2823 divided by 764 is 3 with a remainder of 531.
Use 3 as the next digit of our solution. 
Result so far: 7133.0
The remainder is 531 after subtracting 2292 from 2823.
Bring next digit (8) of the dividend behind the 531 and repeat the process: 5318 / 764

Let's proceed to step 8:
764 goes into 5318 6 times with a remainder of 734.
The next digit of our result is 6. 
Result so far: 71336.0
Deduct 4584 from 5318 and we're left with 734.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7340, and continue the process.

Let's proceed to step 9:
764 goes into 7340 9 times with a remainder of 464.
The number 9 becomes the next digit in our result. 
Result so far: 71336.9
Deduct 6876 from 7340 and we're left with 464.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4640, and continue the process.

Moving on to step 10:
764 goes into 4640 6 times with a remainder of 56.
The next digit of our result is 6. 
Result so far: 71336.96
The remainder is 56 after subtracting 4584 from 4640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Moving on to step 11:
560 divided by 764 is 0 with a remainder of 560.
Put 0 as the next digit of the answer. 
Result so far: 71336.96
Subtracting 0 from 560 leaves us with 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Step 12:
The number 764 fits into 5600 7 times, leaving a remainder of 252.
Use 7 as the next digit of our solution. 
Result so far: 71336.9607
The remainder is 252 after subtracting 5348 from 5600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

Let's proceed to step 13:
2520 divided by 764 is 3 with a remainder of 228.
Use 3 as the next digit of our solution. 
Result so far: 71336.96073
The remainder is 228 after subtracting 2292 from 2520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2280, and continue the process.

On to step 14:
When dividing 2280 by 764, we get 2 with a remainder of 752.
The next digit of our result is 2. 
Result so far: 71336.960732
The remainder is 752 after subtracting 1528 from 2280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7520, and continue the process.

Let's proceed to step 15:
764 can be fit into 7520 9 times, resulting in a remainder of 644.
The number 9 becomes the next digit in our result. 
Result so far: 71336.9607329
The remainder is 644 after subtracting 6876 from 7520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6440, and continue the process.

Moving on to step 16:
6440 divided by 764 is 8 with a remainder of 328.
Put 8 as the next digit of the answer. 
Result so far: 71336.96073298
If we subtract 6112 from 6440, we get 328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

The final outcome is 71336.96073298, with a leftover of 3.28e-07.
