53363693 divided by 398 
Our goal is to divide 53363693 by 398.

Step 1:
The number 398 fits into 5 0 times, leaving a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Bring next digit (3) of the dividend behind the 5 and repeat the process: 53 / 398

Moving on to step 2:
398 goes into 53 0 times with a remainder of 53.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 53 leaves us with 53.
Include the next digit (3) from the dividend after 53, then repeat: 533 / 398

Let's proceed to step 3:
398 goes into 533 1 times with a remainder of 135.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 398 from 533 to get 135.
Fetch the next digit (6) from the dividend, attach it to 135 and continue: 1356 / 398

Going ahead to step 4:
398 can be fit into 1356 3 times, resulting in a remainder of 162.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
Subtract 1194 from 1356 to get 162.
Grab the next digit (3) from the dividend, add it to 162, then carry on: 1623 / 398

Step 5:
398 goes into 1623 4 times with a remainder of 31.
Use 4 as the next digit of our solution. 
Result so far: 134.0
The remainder is 31 after subtracting 1592 from 1623.
Grab the next digit (6) from the dividend, add it to 31, then carry on: 316 / 398

Advancing to step 6:
398 can be fit into 316 0 times, resulting in a remainder of 316.
The next digit of our result is 0. 
Result so far: 1340.0
Subtract 0 from 316 to get 316.
Take the next digit (9) from the dividend and append it to 316, then repeat: 3169 / 398

Step 7:
398 can be fit into 3169 7 times, resulting in a remainder of 383.
Use 7 as the next digit of our solution. 
Result so far: 13407.0
Deduct 2786 from 3169 and we're left with 383.
Include the next digit (3) from the dividend after 383, then repeat: 3833 / 398

Step 8:
3833 divided by 398 is 9 with a remainder of 251.
Use 9 as the next digit of our solution. 
Result so far: 134079.0
Deduct 3582 from 3833 and we're left with 251.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2510, and continue the process.

Let's proceed to step 9:
The number 398 fits into 2510 6 times, leaving a remainder of 122.
Write down 6 as next digit of the result. 
Result so far: 134079.6
Subtract 2388 from 2510 to get 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

On to step 10:
When dividing 1220 by 398, we get 3 with a remainder of 26.
Put 3 as the next digit of the answer. 
Result so far: 134079.63
If we subtract 1194 from 1220, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Moving on to step 11:
When dividing 260 by 398, we get 0 with a remainder of 260.
Record the quotient 0 as the next digit in the result. 
Result so far: 134079.63
Subtracting 0 from 260 leaves us with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Let's proceed to step 12:
398 goes into 2600 6 times with a remainder of 212.
The number 6 becomes the next digit in our result. 
Result so far: 134079.6306
Deduct 2388 from 2600 and we're left 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.

Advancing to step 13:
398 can be fit into 2120 5 times, resulting in a remainder of 130.
The number 5 becomes the next digit in our result. 
Result so far: 134079.63065
Subtracting 1990 from 2120 leaves us with 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 14:
398 can be fit into 1300 3 times, resulting in a remainder of 106.
Record the quotient 3 as the next digit in the result. 
Result so far: 134079.630653
The remainder is 106 after subtracting 1194 from 1300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Going ahead to step 15:
398 can be fit into 1060 2 times, resulting in a remainder of 264.
The next digit of our result is 2. 
Result so far: 134079.6306532
Deduct 796 from 1060 and we're left with 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 16:
398 goes into 2640 6 times with a remainder of 252.
Put 6 as the next digit of the answer. 
Result so far: 134079.63065326
The remainder is 252 after subtracting 2388 from 2640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

The final outcome is 134079.63065326, with a leftover of 2.52e-07.
