Let's divide 84890428 by 398
Our goal is to divide 84890428 by 398.

Let's proceed to step 1:
398 goes into 8 0 times with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Fetch the next digit (4) from the dividend, attach it to 8 and continue: 84 / 398

On to step 2:
398 goes into 84 0 times with a remainder of 84.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 84 to get 84.
Take the next digit (8) from the dividend and append it to 84, then repeat: 848 / 398

Let's proceed to step 3:
398 goes into 848 2 times with a remainder of 52.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtracting 796 from 848 leaves us with 52.
Fetch the next digit (9) from the dividend, attach it to 52 and continue: 529 / 398

On to step 4:
398 goes into 529 1 times with a remainder of 131.
Write down 1 as next digit of the result. 
Result so far: 21.0
Subtracting 398 from 529 leaves us with 131.
Grab the next digit (0) from the dividend, add it to 131, then carry on: 1310 / 398

On to step 5:
398 goes into 1310 3 times with a remainder of 116.
Put 3 as the next digit of the answer. 
Result so far: 213.0
If we subtract 1194 from 1310, we get 116.
Append the next digit (4) from the dividend to 116 and continue with: 1164 / 398

Advancing to step 6:
When dividing 1164 by 398, we get 2 with a remainder of 368.
Record the quotient 2 as the next digit in the result. 
Result so far: 2132.0
Subtracting 796 from 1164 leaves us with 368.
Fetch the next digit (2) from the dividend, attach it to 368 and continue: 3682 / 398

Step 7:
When dividing 3682 by 398, we get 9 with a remainder of 100.
The number 9 becomes the next digit in our result. 
Result so far: 21329.0
Deduct 3582 from 3682 and we're left with 100.
Append the next digit (8) from the dividend to 100 and continue with: 1008 / 398

Advancing to step 8:
If we divide 1008 by 398, we get 2 and a remainder of 212.
The next digit of our result is 2. 
Result so far: 213292.0
If we take 796 away from 1008, we end up with 212.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

On to step 9:
When dividing 2120 by 398, we get 5 with a remainder of 130.
Put 5 as the next digit of the answer. 
Result so far: 213292.5
Subtract 1990 from 2120 to get 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Step 10:
If we divide 1300 by 398, we get 3 and a remainder of 106.
Put 3 as the next digit of the answer. 
Result so far: 213292.53
Subtract 1194 from 1300 to get 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Moving on to step 11:
398 goes into 1060 2 times with a remainder of 264.
The number 2 becomes the next digit in our result. 
Result so far: 213292.532
If we subtract 796 from 1060, we get 264.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

Step 12:
The number 398 fits into 2640 6 times, leaving a remainder of 252.
Use 6 as the next digit of our solution. 
Result so far: 213292.5326
Subtract 2388 from 2640 to get 252.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

Going ahead to step 13:
398 goes into 2520 6 times with a remainder of 132.
The number 6 becomes the next digit in our result. 
Result so far: 213292.53266
If we subtract 2388 from 2520, we get 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

The final result is 213292.53266 with a remainder of 0.000132.
