398158 ÷ 53 
Let's see how many times 53 fits into 398158.

Let's proceed to step 1:
3 divided by 53 is 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Include the next digit (9) from the dividend after 3, then repeat: 39 / 53

On to step 2:
39 divided by 53 is 0 with a remainder of 39.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 39 after subtracting 0 from 39.
Bring next digit (8) of the dividend behind the 39 and repeat the process: 398 / 53

On to step 3:
The number 53 fits into 398 7 times, leaving a remainder of 27.
Write down 7 as next digit of the result. 
Result so far: 7.0
The remainder is 27 after subtracting 371 from 398.
Append the next digit (1) from the dividend to 27 and continue with: 271 / 53

Moving on to step 4:
If we divide 271 by 53, we get 5 and a remainder of 6.
The number 5 becomes the next digit in our result. 
Result so far: 75.0
Subtracting 265 from 271 leaves us with 6.
Take the next digit (5) from the dividend and append it to 6, then repeat: 65 / 53

On to step 5:
53 goes into 65 1 times with a remainder of 12.
The next digit of our result is 1. 
Result so far: 751.0
If we take 53 away from 65, we end up with 12.
Grab the next digit (8) from the dividend, add it to 12, then carry on: 128 / 53

Let's proceed to step 6:
If we divide 128 by 53, we get 2 and a remainder of 22.
Record the quotient 2 as the next digit in the result. 
Result so far: 7512.0
If we subtract 106 from 128, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 7:
When dividing 220 by 53, we get 4 with a remainder of 8.
The next digit of our result is 4. 
Result so far: 7512.4
Deduct 212 from 220 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 8:
When dividing 80 by 53, we get 1 with a remainder of 27.
Record the quotient 1 as the next digit in the result. 
Result so far: 7512.41
Deduct 53 from 80 and we're left with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Moving on to step 9:
53 goes into 270 5 times with a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 7512.415
If we take 265 away from 270, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 10:
50 divided by 53 is 0 with a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 7512.415
Subtract 0 from 50 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 11:
500 divided by 53 is 9 with a remainder of 23.
Put 9 as the next digit of the answer. 
Result so far: 7512.41509
The remainder is 23 after subtracting 477 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Moving on to step 12:
When dividing 230 by 53, we get 4 with a remainder of 18.
Put 4 as the next digit of the answer. 
Result so far: 7512.415094
Subtract 212 from 230 to 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.

Advancing to step 13:
The number 53 fits into 180 3 times, leaving a remainder of 21.
Put 3 as the next digit of the answer. 
Result so far: 7512.4150943
If we take 159 away from 180, we end up with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Step 14:
If we divide 210 by 53, we get 3 and a remainder of 51.
Record the quotient 3 as the next digit in the result. 
Result so far: 7512.41509433
Deduct 159 from 210 and we're left with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

The final result is 7512.41509433 with a remainder of 5.1e-08.
