We look at the division of 76866927 by 521 
We want to divide 76866927 by 521.

On to step 1:
521 goes into 7 0 times with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Append the next digit (6) from the dividend to 7 and continue with: 76 / 521

Going ahead to step 2:
The number 521 fits into 76 0 times, leaving a remainder of 76.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 76 leaves us with 76.
Fetch the next digit (8) from the dividend, attach it to 76 and continue: 768 / 521

On to step 3:
521 can be fit into 768 1 times, resulting in a remainder of 247.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 521 from 768, we get 247.
Fetch the next digit (6) from the dividend, attach it to 247 and continue: 2476 / 521

Moving on to step 4:
521 can be fit into 2476 4 times, resulting in a remainder of 392.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
Deduct 2084 from 2476 and we're left with 392.
Fetch the next digit (6) from the dividend, attach it to 392 and continue: 3926 / 521

Step 5:
521 goes into 3926 7 times with a remainder of 279.
Put 7 as the next digit of the answer. 
Result so far: 147.0
If we take 3647 away from 3926, we end up with 279.
Take the next digit (9) from the dividend and append it to 279, then repeat: 2799 / 521

On to step 6:
When dividing 2799 by 521, we get 5 with a remainder of 194.
Use 5 as the next digit of our solution. 
Result so far: 1475.0
If we subtract 2605 from 2799, we get 194.
Grab the next digit (2) from the dividend, add it to 194, then carry on: 1942 / 521

On to step 7:
When dividing 1942 by 521, we get 3 with a remainder of 379.
Put 3 as the next digit of the answer. 
Result so far: 14753.0
The remainder is 379 after subtracting 1563 from 1942.
Take the next digit (7) from the dividend and append it to 379, then repeat: 3797 / 521

Moving on to step 8:
3797 divided by 521 is 7 with a remainder of 150.
Record the quotient 7 as the next digit in the result. 
Result so far: 147537.0
Subtract 3647 from 3797 to get 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Going ahead to step 9:
The number 521 fits into 1500 2 times, leaving a remainder of 458.
The number 2 becomes the next digit in our result. 
Result so far: 147537.2
Subtracting 1042 from 1500 leaves us with 458.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4580, and continue the process.

Let's proceed to step 10:
When dividing 4580 by 521, we get 8 with a remainder of 412.
The next digit of our result is 8. 
Result so far: 147537.28
If we subtract 4168 from 4580, we get 412.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4120, and continue the process.

Moving on to step 11:
When dividing 4120 by 521, we get 7 with a remainder of 473.
Put 7 as the next digit of the answer. 
Result so far: 147537.287
If we subtract 3647 from 4120, we get 473.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4730, and continue the process.

Going ahead to step 12:
521 can be fit into 4730 9 times, resulting in a remainder of 41.
Record the quotient 9 as the next digit in the result. 
Result so far: 147537.2879
Subtract 4689 from 4730 to get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Advancing to step 13:
If we divide 410 by 521, we get 0 and a remainder of 410.
Put 0 as the next digit of the answer. 
Result so far: 147537.2879
Subtracting 0 from 410 leaves us with 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4100, and continue the process.

Going ahead to step 14:
When dividing 4100 by 521, we get 7 with a remainder of 453.
The next digit of our result is 7. 
Result so far: 147537.287907
Subtract 3647 from 4100 to get 453.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4530, and continue the process.

Advancing to step 15:
If we divide 4530 by 521, we get 8 and a remainder of 362.
Put 8 as the next digit of the answer. 
Result so far: 147537.2879078
If we subtract 4168 from 4530, we get 362.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3620, and continue the process.

Let's proceed to step 16:
When dividing 3620 by 521, we get 6 with a remainder of 494.
Use 6 as the next digit of our solution. 
Result so far: 147537.28790786
Subtract 3126 from 3620 to get 494.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4940, and continue the process.

The quotient of the division is 147537.28790786, and the remainder is 4.94e-07.
