We're dividing 20263857 by 437 
We want to divide 20263857 by 437.

Advancing to step 1:
The number 437 fits into 2 0 times, leaving a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Grab the next digit (0) from the dividend, add it to 2, then carry on: 20 / 437

Moving on to step 2:
20 divided by 437 is 0 with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 20 to get 20.
Include the next digit (2) from the dividend after 20, then repeat: 202 / 437

Advancing to step 3:
The number 437 fits into 202 0 times, leaving a remainder of 202.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 202 leaves us with 202.
Append the next digit (6) from the dividend to 202 and continue with: 2026 / 437

Going ahead to step 4:
2026 divided by 437 is 4 with a remainder of 278.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
The remainder is 278 after subtracting 1748 from 2026.
Include the next digit (3) from the dividend after 278, then repeat: 2783 / 437

Let's proceed to step 5:
If we divide 2783 by 437, we get 6 and a remainder of 161.
Record the quotient 6 as the next digit in the result. 
Result so far: 46.0
If we take 2622 away from 2783, we end up with 161.
Include the next digit (8) from the dividend after 161, then repeat: 1618 / 437

Let's proceed to step 6:
437 can be fit into 1618 3 times, resulting in a remainder of 307.
Use 3 as the next digit of our solution. 
Result so far: 463.0
If we take 1311 away from 1618, we end up with 307.
Take the next digit (5) from the dividend and append it to 307, then repeat: 3075 / 437

Step 7:
The number 437 fits into 3075 7 times, leaving a remainder of 16.
Record the quotient 7 as the next digit in the result. 
Result so far: 4637.0
Deduct 3059 from 3075 and we're left with 16.
Fetch the next digit (7) from the dividend, attach it to 16 and continue: 167 / 437

Advancing to step 8:
167 divided by 437 is 0 with a remainder of 167.
Use 0 as the next digit of our solution. 
Result so far: 46370.0
Subtract 0 from 167 to get 167.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1670, and continue the process.

Moving on to step 9:
If we divide 1670 by 437, we get 3 and a remainder of 359.
The number 3 becomes the next digit in our result. 
Result so far: 46370.3
If we take 1311 away from 1670, we end up with 359.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3590, and continue the process.

Advancing to step 10:
If we divide 3590 by 437, we get 8 and a remainder of 94.
The number 8 becomes the next digit in our result. 
Result so far: 46370.38
If we take 3496 away from 3590, we end up with 94.
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 11:
940 divided by 437 is 2 with a remainder of 66.
Write down 2 as next digit of the result. 
Result so far: 46370.382
Subtracting 874 from 940 leaves us with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Going ahead to step 12:
437 goes into 660 1 times with a remainder of 223.
The next digit of our result is 1. 
Result so far: 46370.3821
If we subtract 437 from 660, we get 223.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2230, and continue the process.

Let's proceed to step 13:
If we divide 2230 by 437, we get 5 and a remainder of 45.
The next digit of our result is 5. 
Result so far: 46370.38215
If we take 2185 away from 2230, we end up with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Step 14:
The number 437 fits into 450 1 times, leaving a remainder of 13.
Record the quotient 1 as the next digit in the result. 
Result so far: 46370.382151
If we subtract 437 from 450, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 15:
130 divided by 437 is 0 with a remainder of 130.
Write down 0 as next digit of the result. 
Result so far: 46370.382151
Subtract 0 from 130 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.

Moving on to step 16:
437 goes into 1300 2 times with a remainder of 426.
Record the quotient 2 as the next digit in the result. 
Result so far: 46370.38215102
Deduct 874 from 1300 and we're left with 426.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4260, and continue the process.

The final outcome is 46370.38215102, with a leftover of 4.26e-07.
