We're dividing 8374898 by 421 
Let's see how many times 421 fits into 8374898.

Let's proceed to step 1:
8 divided by 421 is 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Take the next digit (3) from the dividend and append it to 8, then repeat: 83 / 421

Advancing to step 2:
421 goes into 83 0 times with a remainder of 83.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 83 to get 83.
Bring next digit (7) of the dividend behind the 83 and repeat the process: 837 / 421

Step 3:
421 can be fit into 837 1 times, resulting in a remainder of 416.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 416 after subtracting 421 from 837.
Bring next digit (4) of the dividend behind the 416 and repeat the process: 4164 / 421

Moving on to step 4:
When dividing 4164 by 421, we get 9 with a remainder of 375.
Write down 9 as next digit of the result. 
Result so far: 19.0
Deduct 3789 from 4164 and we're left with 375.
Include the next digit (8) from the dividend after 375, then repeat: 3758 / 421

Step 5:
421 can be fit into 3758 8 times, resulting in a remainder of 390.
Put 8 as the next digit of the answer. 
Result so far: 198.0
If we take 3368 away from 3758, we end up with 390.
Include the next digit (9) from the dividend after 390, then repeat: 3909 / 421

Going ahead to step 6:
The number 421 fits into 3909 9 times, leaving a remainder of 120.
Put 9 as the next digit of the answer. 
Result so far: 1989.0
If we subtract 3789 from 3909, we get 120.
Grab the next digit (8) from the dividend, add it to 120, then carry on: 1208 / 421

Let's proceed to step 7:
421 goes into 1208 2 times with a remainder of 366.
Use 2 as the next digit of our solution. 
Result so far: 19892.0
Deduct 842 from 1208 and we're left with 366.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3660, and continue the process.

Advancing to step 8:
421 can be fit into 3660 8 times, resulting in a remainder of 292.
Put 8 as the next digit of the answer. 
Result so far: 19892.8
Deduct 3368 from 3660 and we're left with 292.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2920, and continue the process.

Let's proceed to step 9:
The number 421 fits into 2920 6 times, leaving a remainder of 394.
Record the quotient 6 as the next digit in the result. 
Result so far: 19892.86
Deduct 2526 from 2920 and we're left with 394.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3940, and continue the process.

On to step 10:
When dividing 3940 by 421, we get 9 with a remainder of 151.
Record the quotient 9 as the next digit in the result. 
Result so far: 19892.869
If we subtract 3789 from 3940, we get 151.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1510, and continue the process.

On to step 11:
The number 421 fits into 1510 3 times, leaving a remainder of 247.
Write down 3 as next digit of the result. 
Result so far: 19892.8693
Subtract 1263 from 1510 to get 247.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2470, and continue the process.

Going ahead to step 12:
When dividing 2470 by 421, we get 5 with a remainder of 365.
Write down 5 as next digit of the result. 
Result so far: 19892.86935
Subtract 2105 from 2470 to get 365.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3650, and continue the process.

Going ahead to step 13:
The number 421 fits into 3650 8 times, leaving a remainder of 282.
Write down 8 as next digit of the result. 
Result so far: 19892.869358
If we take 3368 away from 3650, we end up with 282.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2820, and continue the process.

Step 14:
If we divide 2820 by 421, we get 6 and a remainder of 294.
Put 6 as the next digit of the answer. 
Result so far: 19892.8693586
The remainder is 294 after subtracting 2526 from 2820.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2940, and continue the process.

Going ahead to step 15:
When dividing 2940 by 421, we get 6 with a remainder of 414.
Use 6 as the next digit of our solution. 
Result so far: 19892.86935866
Subtracting 2526 from 2940 leaves us with 414.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4140, and continue the process.

In conclusion, the division gives 19892.86935866 with a balance of 4.14e-07.
