75720883 ÷ 521 
We want to divide 75720883 by 521.

Going ahead to step 1:
521 goes into 7 0 times with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Grab the next digit (5) from the dividend, add it to 7, then carry on: 75 / 521

Let's proceed to step 2:
If we divide 75 by 521, we get 0 and a remainder of 75.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 75 leaves us with 75.
Append the next digit (7) from the dividend to 75 and continue with: 757 / 521

Let's proceed to step 3:
When dividing 757 by 521, we get 1 with a remainder of 236.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 236 after subtracting 521 from 757.
Include the next digit (2) from the dividend after 236, then repeat: 2362 / 521

Let's proceed to step 4:
521 goes into 2362 4 times with a remainder of 278.
The next digit of our result is 4. 
Result so far: 14.0
Deduct 2084 from 2362 and we're left with 278.
Take the next digit (0) from the dividend and append it to 278, then repeat: 2780 / 521

Moving on to step 5:
521 goes into 2780 5 times with a remainder of 175.
Record the quotient 5 as the next digit in the result. 
Result so far: 145.0
Subtract 2605 from 2780 to get 175.
Include the next digit (8) from the dividend after 175, then repeat: 1758 / 521

Step 6:
If we divide 1758 by 521, we get 3 and a remainder of 195.
Record the quotient 3 as the next digit in the result. 
Result so far: 1453.0
The remainder is 195 after subtracting 1563 from 1758.
Include the next digit (8) from the dividend after 195, then repeat: 1958 / 521

Moving on to step 7:
The number 521 fits into 1958 3 times, leaving a remainder of 395.
Record the quotient 3 as the next digit in the result. 
Result so far: 14533.0
The remainder is 395 after subtracting 1563 from 1958.
Grab the next digit (3) from the dividend, add it to 395, then carry on: 3953 / 521

Let's proceed to step 8:
521 goes into 3953 7 times with a remainder of 306.
Record the quotient 7 as the next digit in the result. 
Result so far: 145337.0
Subtracting 3647 from 3953 leaves us with 306.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3060, and continue the process.

Going ahead to step 9:
3060 divided by 521 is 5 with a remainder of 455.
Write down 5 as next digit of the result. 
Result so far: 145337.5
Subtract 2605 from 3060 to get 455.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4550, and continue the process.

Going ahead to step 10:
521 can be fit into 4550 8 times, resulting in a remainder of 382.
Put 8 as the next digit of the answer. 
Result so far: 145337.58
If we take 4168 away from 4550, we end up with 382.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3820, and continue the process.

Advancing to step 11:
The number 521 fits into 3820 7 times, leaving a remainder of 173.
Use 7 as the next digit of our solution. 
Result so far: 145337.587
If we take 3647 away from 3820, we end up with 173.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1730, and continue the process.

Going ahead to step 12:
1730 divided by 521 is 3 with a remainder of 167.
Put 3 as the next digit of the answer. 
Result so far: 145337.5873
If we take 1563 away from 1730, we end up with 167.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1670, and continue the process.

Advancing to step 13:
1670 divided by 521 is 3 with a remainder of 107.
Write down 3 as next digit of the result. 
Result so far: 145337.58733
If we take 1563 away from 1670, we end up with 107.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1070, and continue the process.

The quotient of the division is 145337.58733, and the remainder is 0.000107.
