We're dividing 20342991 by 398 
Let's see how many times 398 fits into 20342991.

Moving on to step 1:
When dividing 2 by 398, we get 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Append the next digit (0) from the dividend to 2 and continue with: 20 / 398

Step 2:
398 can be fit into 20 0 times, resulting in a remainder of 20.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 20 to get 20.
Grab the next digit (3) from the dividend, add it to 20, then carry on: 203 / 398

Moving on to step 3:
The number 398 fits into 203 0 times, leaving a remainder of 203.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 203 to get 203.
Bring next digit (4) of the dividend behind the 203 and repeat the process: 2034 / 398

Moving on to step 4:
If we divide 2034 by 398, we get 5 and a remainder of 44.
Write down 5 as next digit of the result. 
Result so far: 5.0
The remainder is 44 after subtracting 1990 from 2034.
Fetch the next digit (2) from the dividend, attach it to 44 and continue: 442 / 398

Step 5:
398 can be fit into 442 1 times, resulting in a remainder of 44.
The next digit of our result is 1. 
Result so far: 51.0
If we subtract 398 from 442, we get 44.
Include the next digit (9) from the dividend after 44, then repeat: 449 / 398

On to step 6:
When dividing 449 by 398, we get 1 with a remainder of 51.
Record the quotient 1 as the next digit in the result. 
Result so far: 511.0
The remainder is 51 after subtracting 398 from 449.
Fetch the next digit (9) from the dividend, attach it to 51 and continue: 519 / 398

Moving on to step 7:
When dividing 519 by 398, we get 1 with a remainder of 121.
Use 1 as the next digit of our solution. 
Result so far: 5111.0
Subtract 398 from 519 to get 121.
Append the next digit (1) from the dividend to 121 and continue with: 1211 / 398

Going ahead to step 8:
When dividing 1211 by 398, we get 3 with a remainder of 17.
Record the quotient 3 as the next digit in the result. 
Result so far: 51113.0
Deduct 1194 from 1211 and we're left with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Moving on to step 9:
When dividing 170 by 398, we get 0 with a remainder of 170.
Use 0 as the next digit of our solution. 
Result so far: 51113.0
If we take 0 away from 170, we end up with 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

On to step 10:
The number 398 fits into 1700 4 times, leaving a remainder of 108.
The next digit of our result is 4. 
Result so far: 51113.04
The remainder is 108 after subtracting 1592 from 1700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Going ahead to step 11:
The number 398 fits into 1080 2 times, leaving a remainder of 284.
Write down 2 as next digit of the result. 
Result so far: 51113.042
The remainder is 284 after subtracting 796 from 1080.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2840, and continue the process.

Moving on to step 12:
The number 398 fits into 2840 7 times, leaving a remainder of 54.
Write down 7 as next digit of the result. 
Result so far: 51113.0427
The remainder is 54 after subtracting 2786 from 2840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Let's proceed to step 13:
If we divide 540 by 398, we get 1 and a remainder of 142.
Write down 1 as next digit of the result. 
Result so far: 51113.04271
Deduct 398 from 540 and we're left with 142.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1420, and continue the process.

Step 14:
If we divide 1420 by 398, we get 3 and a remainder of 226.
Use 3 as the next digit of our solution. 
Result so far: 51113.042713
Subtracting 1194 from 1420 leaves us with 226.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2260, and continue the process.

Advancing to step 15:
If we divide 2260 by 398, we get 5 and a remainder of 270.
Write down 5 as next digit of the result. 
Result so far: 51113.0427135
Subtract 1990 from 2260 to get 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Advancing to step 16:
When dividing 2700 by 398, we get 6 with a remainder of 312.
Record the quotient 6 as the next digit in the result. 
Result so far: 51113.04271356
Subtract 2388 from 2700 to get 312.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

The quotient of the division is 51113.04271356, and the remainder is 3.12e-07.
