We're dividing 80021961 by 507 
We want to divide 80021961 by 507.

Moving on to step 1:
If we divide 8 by 507, we get 0 and a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Fetch the next digit (0) from the dividend, attach it to 8 and continue: 80 / 507

Moving on to step 2:
The number 507 fits into 80 0 times, leaving a remainder of 80.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 80 leaves us with 80.
Grab the next digit (0) from the dividend, add it to 80, then carry on: 800 / 507

Going ahead to step 3:
507 can be fit into 800 1 times, resulting in a remainder of 293.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 507 from 800 and we're left with 293.
Grab the next digit (2) from the dividend, add it to 293, then carry on: 2932 / 507

Going ahead to step 4:
When dividing 2932 by 507, we get 5 with a remainder of 397.
Write down 5 as next digit of the result. 
Result so far: 15.0
If we take 2535 away from 2932, we end up with 397.
Bring next digit (1) of the dividend behind the 397 and repeat the process: 3971 / 507

Step 5:
The number 507 fits into 3971 7 times, leaving a remainder of 422.
The number 7 becomes the next digit in our result. 
Result so far: 157.0
Subtracting 3549 from 3971 leaves us with 422.
Include the next digit (9) from the dividend after 422, then repeat: 4229 / 507

On to step 6:
The number 507 fits into 4229 8 times, leaving a remainder of 173.
Record the quotient 8 as the next digit in the result. 
Result so far: 1578.0
If we take 4056 away from 4229, we end up with 173.
Append the next digit (6) from the dividend to 173 and continue with: 1736 / 507

Going ahead to step 7:
507 can be fit into 1736 3 times, resulting in a remainder of 215.
Write down 3 as next digit of the result. 
Result so far: 15783.0
If we take 1521 away from 1736, we end up with 215.
Include the next digit (1) from the dividend after 215, then repeat: 2151 / 507

Going ahead to step 8:
507 goes into 2151 4 times with a remainder of 123.
The number 4 becomes the next digit in our result. 
Result so far: 157834.0
If we take 2028 away from 2151, we end up with 123.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1230, and continue the process.

Going ahead to step 9:
507 goes into 1230 2 times with a remainder of 216.
Record the quotient 2 as the next digit in the result. 
Result so far: 157834.2
If we take 1014 away from 1230, we end up with 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

Going ahead to step 10:
If we divide 2160 by 507, we get 4 and a remainder of 132.
The next digit of our result is 4. 
Result so far: 157834.24
Deduct 2028 from 2160 and we're left with 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Going ahead to step 11:
507 can be fit into 1320 2 times, resulting in a remainder of 306.
Use 2 as the next digit of our solution. 
Result so far: 157834.242
Subtracting 1014 from 1320 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.

Moving on to step 12:
If we divide 3060 by 507, we get 6 and a remainder of 18.
The next digit of our result is 6. 
Result so far: 157834.2426
If we subtract 3042 from 3060, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 13:
The number 507 fits into 180 0 times, leaving a remainder of 180.
The number 0 becomes the next digit in our result. 
Result so far: 157834.2426
If we take 0 away from 180, we end up with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Step 14:
When dividing 1800 by 507, we get 3 with a remainder of 279.
Write down 3 as next digit of the result. 
Result so far: 157834.242603
Subtracting 1521 from 1800 leaves us with 279.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2790, and continue the process.

Moving on to step 15:
507 goes into 2790 5 times with a remainder of 255.
Write down 5 as next digit of the result. 
Result so far: 157834.2426035
Subtracting 2535 from 2790 leaves us with 255.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2550, and continue the process.

Moving on to step 16:
507 can be fit into 2550 5 times, resulting in a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 157834.24260355
Subtract 2535 from 2550 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

The final outcome is 157834.24260355, with a leftover of 1.5e-08.
