We're dividing 42978716 by 398 
Let's see how many times 398 fits into 42978716.

Moving on to step 1:
If we divide 4 by 398, we get 0 and a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Fetch the next digit (2) from the dividend, attach it to 4 and continue: 42 / 398

Going ahead to step 2:
42 divided by 398 is 0 with a remainder of 42.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 42, we end up with 42.
Bring next digit (9) of the dividend behind the 42 and repeat the process: 429 / 398

Going ahead to step 3:
398 goes into 429 1 times with a remainder of 31.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 398 from 429, we get 31.
Bring next digit (7) of the dividend behind the 31 and repeat the process: 317 / 398

Let's proceed to step 4:
The number 398 fits into 317 0 times, leaving a remainder of 317.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
If we subtract 0 from 317, we get 317.
Take the next digit (8) from the dividend and append it to 317, then repeat: 3178 / 398

Let's proceed to step 5:
398 goes into 3178 7 times with a remainder of 392.
The number 7 becomes the next digit in our result. 
Result so far: 107.0
Subtract 2786 from 3178 to get 392.
Grab the next digit (7) from the dividend, add it to 392, then carry on: 3927 / 398

Let's proceed to step 6:
398 goes into 3927 9 times with a remainder of 345.
Put 9 as the next digit of the answer. 
Result so far: 1079.0
Subtract 3582 from 3927 to get 345.
Include the next digit (1) from the dividend after 345, then repeat: 3451 / 398

Going ahead to step 7:
When dividing 3451 by 398, we get 8 with a remainder of 267.
The number 8 becomes the next digit in our result. 
Result so far: 10798.0
If we take 3184 away from 3451, we end up with 267.
Include the next digit (6) from the dividend after 267, then repeat: 2676 / 398

Step 8:
When dividing 2676 by 398, we get 6 with a remainder of 288.
Write down 6 as next digit of the result. 
Result so far: 107986.0
The remainder is 288 after subtracting 2388 from 2676.
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 9:
2880 divided by 398 is 7 with a remainder of 94.
Use 7 as the next digit of our solution. 
Result so far: 107986.7
The remainder is 94 after subtracting 2786 from 2880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Let's proceed to step 10:
940 divided by 398 is 2 with a remainder of 144.
The number 2 becomes the next digit in our result. 
Result so far: 107986.72
If we subtract 796 from 940, we get 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Let's proceed to step 11:
1440 divided by 398 is 3 with a remainder of 246.
The number 3 becomes the next digit in our result. 
Result so far: 107986.723
If we take 1194 away from 1440, we end up with 246.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2460, and continue the process.

On to step 12:
398 can be fit into 2460 6 times, resulting in a remainder of 72.
Put 6 as the next digit of the answer. 
Result so far: 107986.7236
If we subtract 2388 from 2460, we get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Let's proceed to step 13:
When dividing 720 by 398, we get 1 with a remainder of 322.
Record the quotient 1 as the next digit in the result. 
Result so far: 107986.72361
Subtracting 398 from 720 leaves us with 322.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3220, and continue the process.

Step 14:
3220 divided by 398 is 8 with a remainder of 36.
Put 8 as the next digit of the answer. 
Result so far: 107986.723618
Subtracting 3184 from 3220 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 15:
398 can be fit into 360 0 times, resulting in a remainder of 360.
The next digit of our result is 0. 
Result so far: 107986.723618
If we subtract 0 from 360, we get 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Going ahead to step 16:
When dividing 3600 by 398, we get 9 with a remainder of 18.
The number 9 becomes the next digit in our result. 
Result so far: 107986.72361809
If we subtract 3582 from 3600, 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.

In conclusion, the division gives 107986.72361809 with a balance of 1.8e-08.
