80861248 divided by 421 
Let's see how many times 421 fits into 80861248.

Advancing to step 1:
When dividing 8 by 421, we get 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Take the next digit (0) from the dividend and append it to 8, then repeat: 80 / 421

Step 2:
If we divide 80 by 421, we get 0 and a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 80 leaves us with 80.
Grab the next digit (8) from the dividend, add it to 80, then carry on: 808 / 421

Let's proceed to step 3:
When dividing 808 by 421, we get 1 with a remainder of 387.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 421 from 808, we get 387.
Fetch the next digit (6) from the dividend, attach it to 387 and continue: 3876 / 421

Let's proceed to step 4:
When dividing 3876 by 421, we get 9 with a remainder of 87.
Put 9 as the next digit of the answer. 
Result so far: 19.0
Subtracting 3789 from 3876 leaves us with 87.
Include the next digit (1) from the dividend after 87, then repeat: 871 / 421

Let's proceed to step 5:
421 goes into 871 2 times with a remainder of 29.
Record the quotient 2 as the next digit in the result. 
Result so far: 192.0
The remainder is 29 after subtracting 842 from 871.
Fetch the next digit (2) from the dividend, attach it to 29 and continue: 292 / 421

Let's proceed to step 6:
421 goes into 292 0 times with a remainder of 292.
Put 0 as the next digit of the answer. 
Result so far: 1920.0
If we subtract 0 from 292, we get 292.
Grab the next digit (4) from the dividend, add it to 292, then carry on: 2924 / 421

Let's proceed to step 7:
421 can be fit into 2924 6 times, resulting in a remainder of 398.
Use 6 as the next digit of our solution. 
Result so far: 19206.0
Subtract 2526 from 2924 to get 398.
Bring next digit (8) of the dividend behind the 398 and repeat the process: 3988 / 421

Step 8:
The number 421 fits into 3988 9 times, leaving a remainder of 199.
Write down 9 as next digit of the result. 
Result so far: 192069.0
Subtracting 3789 from 3988 leaves us with 199.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1990, and continue the process.

On to step 9:
When dividing 1990 by 421, we get 4 with a remainder of 306.
Put 4 as the next digit of the answer. 
Result so far: 192069.4
Subtract 1684 from 1990 to get 306.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3060, and continue the process.

Advancing to step 10:
The number 421 fits into 3060 7 times, leaving a remainder of 113.
Record the quotient 7 as the next digit in the result. 
Result so far: 192069.47
If we subtract 2947 from 3060, we get 113.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1130, and continue the process.

Let's proceed to step 11:
421 can be fit into 1130 2 times, resulting in a remainder of 288.
The number 2 becomes the next digit in our result. 
Result so far: 192069.472
Deduct 842 from 1130 and we're left with 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

Going ahead to step 12:
If we divide 2880 by 421, we get 6 and a remainder of 354.
Use 6 as the next digit of our solution. 
Result so far: 192069.4726
The remainder is 354 after subtracting 2526 from 2880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3540, and continue the process.

Let's proceed to step 13:
421 can be fit into 3540 8 times, resulting in a remainder of 172.
Record the quotient 8 as the next digit in the result. 
Result so far: 192069.47268
If we take 3368 away from 3540, we end up with 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

Step 14:
1720 divided by 421 is 4 with a remainder of 36.
Write down 4 as next digit of the result. 
Result so far: 192069.472684
If we subtract 1684 from 1720, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 15:
421 can be fit into 360 0 times, resulting in a remainder of 360.
The number 0 becomes the next digit in our result. 
Result so far: 192069.472684
Deduct 0 from 360 and we're left with 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Advancing to step 16:
421 can be fit into 3600 8 times, resulting in a remainder of 232.
Record the quotient 8 as the next digit in the result. 
Result so far: 192069.47268408
If we subtract 3368 from 3600, we get 232.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

The quotient of the division is 192069.47268408, and the remainder is 2.32e-07.
