We're dividing 52170049 by 398 
We want to divide 52170049 by 398.

On to step 1:
5 divided by 398 is 0 with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Append the next digit (2) from the dividend to 5 and continue with: 52 / 398

Moving on to step 2:
The number 398 fits into 52 0 times, leaving a remainder of 52.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 52 and we're left with 52.
Include the next digit (1) from the dividend after 52, then repeat: 521 / 398

Moving on to step 3:
When dividing 521 by 398, we get 1 with a remainder of 123.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 398 from 521 to get 123.
Grab the next digit (7) from the dividend, add it to 123, then carry on: 1237 / 398

Going ahead to step 4:
398 goes into 1237 3 times with a remainder of 43.
Write down 3 as next digit of the result. 
Result so far: 13.0
If we take 1194 away from 1237, we end up with 43.
Fetch the next digit (0) from the dividend, attach it to 43 and continue: 430 / 398

Moving on to step 5:
If we divide 430 by 398, we get 1 and a remainder of 32.
Record the quotient 1 as the next digit in the result. 
Result so far: 131.0
If we take 398 away from 430, we end up with 32.
Grab the next digit (0) from the dividend, add it to 32, then carry on: 320 / 398

Step 6:
398 goes into 320 0 times with a remainder of 320.
Use 0 as the next digit of our solution. 
Result so far: 1310.0
Deduct 0 from 320 and we're left with 320.
Append the next digit (4) from the dividend to 320 and continue with: 3204 / 398

On to step 7:
The number 398 fits into 3204 8 times, leaving a remainder of 20.
The next digit of our result is 8. 
Result so far: 13108.0
If we subtract 3184 from 3204, we get 20.
Append the next digit (9) from the dividend to 20 and continue with: 209 / 398

Let's proceed to step 8:
209 divided by 398 is 0 with a remainder of 209.
Use 0 as the next digit of our solution. 
Result so far: 131080.0
If we take 0 away from 209, we end up with 209.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2090, and continue the process.

On to step 9:
398 can be fit into 2090 5 times, resulting in a remainder of 100.
The next digit of our result is 5. 
Result so far: 131080.5
Subtract 1990 from 2090 to get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

On to step 10:
1000 divided by 398 is 2 with a remainder of 204.
The next digit of our result is 2. 
Result so far: 131080.52
Deduct 796 from 1000 and we're left with 204.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

Going ahead to step 11:
When dividing 2040 by 398, we get 5 with a remainder of 50.
The number 5 becomes the next digit in our result. 
Result so far: 131080.525
Subtracting 1990 from 2040 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 12:
398 can be fit into 500 1 times, resulting in a remainder of 102.
The next digit of our result is 1. 
Result so far: 131080.5251
If we take 398 away from 500, we end up with 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

Going ahead to step 13:
398 can be fit into 1020 2 times, resulting in a remainder of 224.
Record the quotient 2 as the next digit in the result. 
Result so far: 131080.52512
Subtracting 796 from 1020 leaves us with 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

Going ahead to step 14:
2240 divided by 398 is 5 with a remainder of 250.
Write down 5 as next digit of the result. 
Result so far: 131080.525125
If we take 1990 away from 2240, we end up with 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Let's proceed to step 15:
2500 divided by 398 is 6 with a remainder of 112.
The number 6 becomes the next digit in our result. 
Result so far: 131080.5251256
Subtract 2388 from 2500 to get 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Step 16:
1120 divided by 398 is 2 with a remainder of 324.
Put 2 as the next digit of the answer. 
Result so far: 131080.52512562
Subtract 796 from 1120 to get 324.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3240, and continue the process.

The quotient of the division is 131080.52512562, and the remainder is 3.24e-07.
