We're dividing 80113674 by 521 
We want to figure out the number of times 80113674 can be divided by 521.

Moving on to step 1:
The number 521 fits into 8 0 times, leaving a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Bring next digit (0) of the dividend behind the 8 and repeat the process: 80 / 521

Let's proceed to step 2:
80 divided by 521 is 0 with a remainder of 80.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 80 leaves us with 80.
Include the next digit (1) from the dividend after 80, then repeat: 801 / 521

Step 3:
801 divided by 521 is 1 with a remainder of 280.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 521 from 801, we get 280.
Grab the next digit (1) from the dividend, add it to 280, then carry on: 2801 / 521

Moving on to step 4:
The number 521 fits into 2801 5 times, leaving a remainder of 196.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
Subtracting 2605 from 2801 leaves us with 196.
Fetch the next digit (3) from the dividend, attach it to 196 and continue: 1963 / 521

Moving on to step 5:
The number 521 fits into 1963 3 times, leaving a remainder of 400.
Put 3 as the next digit of the answer. 
Result so far: 153.0
Deduct 1563 from 1963 and we're left with 400.
Grab the next digit (6) from the dividend, add it to 400, then carry on: 4006 / 521

Advancing to step 6:
When dividing 4006 by 521, we get 7 with a remainder of 359.
Write down 7 as next digit of the result. 
Result so far: 1537.0
The remainder is 359 after subtracting 3647 from 4006.
Append the next digit (7) from the dividend to 359 and continue with: 3597 / 521

On to step 7:
The number 521 fits into 3597 6 times, leaving a remainder of 471.
The number 6 becomes the next digit in our result. 
Result so far: 15376.0
Deduct 3126 from 3597 and we're left with 471.
Fetch the next digit (4) from the dividend, attach it to 471 and continue: 4714 / 521

Moving on to step 8:
4714 divided by 521 is 9 with a remainder of 25.
The next digit of our result is 9. 
Result so far: 153769.0
Subtracting 4689 from 4714 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Going ahead to step 9:
521 goes into 250 0 times with a remainder of 250.
Record the quotient 0 as the next digit in the result. 
Result so far: 153769.0
Subtracting 0 from 250 leaves us with 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

On to step 10:
When dividing 2500 by 521, we get 4 with a remainder of 416.
The number 4 becomes the next digit in our result. 
Result so far: 153769.04
If we take 2084 away from 2500, we end up with 416.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

Step 11:
When dividing 4160 by 521, we get 7 with a remainder of 513.
Put 7 as the next digit of the answer. 
Result so far: 153769.047
The remainder is 513 after subtracting 3647 from 4160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5130, and continue the process.

On to step 12:
5130 divided by 521 is 9 with a remainder of 441.
The next digit of our result is 9. 
Result so far: 153769.0479
If we take 4689 away from 5130, we end up with 441.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4410, and continue the process.

Let's proceed to step 13:
521 can be fit into 4410 8 times, resulting in a remainder of 242.
The number 8 becomes the next digit in our result. 
Result so far: 153769.04798
If we subtract 4168 from 4410, we get 242.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2420, and continue the process.

On to step 14:
When dividing 2420 by 521, we get 4 with a remainder of 336.
Put 4 as the next digit of the answer. 
Result so far: 153769.047984
Subtract 2084 from 2420 to get 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

Step 15:
521 goes into 3360 6 times with a remainder of 234.
The next digit of our result is 6. 
Result so far: 153769.0479846
If we subtract 3126 from 3360, we get 234.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2340, and continue the process.

Advancing to step 16:
2340 divided by 521 is 4 with a remainder of 256.
Use 4 as the next digit of our solution. 
Result so far: 153769.04798464
Deduct 2084 from 2340 and we're left with 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

The final outcome is 153769.04798464, with a leftover of 2.56e-07.
