31387888 ÷ 443 
Our goal is to divide 31387888 by 443.

Step 1:
The number 443 fits into 3 0 times, leaving a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Fetch the next digit (1) from the dividend, attach it to 3 and continue: 31 / 443

Let's proceed to step 2:
When dividing 31 by 443, we get 0 with a remainder of 31.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 31 to get 31.
Bring next digit (3) of the dividend behind the 31 and repeat the process: 313 / 443

Let's proceed to step 3:
If we divide 313 by 443, we get 0 and a remainder of 313.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 313 after subtracting 0 from 313.
Include the next digit (8) from the dividend after 313, then repeat: 3138 / 443

Step 4:
3138 divided by 443 is 7 with a remainder of 37.
Write down 7 as next digit of the result. 
Result so far: 7.0
If we take 3101 away from 3138, we end up with 37.
Grab the next digit (7) from the dividend, add it to 37, then carry on: 377 / 443

Step 5:
The number 443 fits into 377 0 times, leaving a remainder of 377.
Use 0 as the next digit of our solution. 
Result so far: 70.0
Deduct 0 from 377 and we're left with 377.
Append the next digit (8) from the dividend to 377 and continue with: 3778 / 443

Let's proceed to step 6:
When dividing 3778 by 443, we get 8 with a remainder of 234.
The number 8 becomes the next digit in our result. 
Result so far: 708.0
Subtract 3544 from 3778 to get 234.
Bring next digit (8) of the dividend behind the 234 and repeat the process: 2348 / 443

Step 7:
If we divide 2348 by 443, we get 5 and a remainder of 133.
Use 5 as the next digit of our solution. 
Result so far: 7085.0
Subtracting 2215 from 2348 leaves us with 133.
Grab the next digit (8) from the dividend, add it to 133, then carry on: 1338 / 443

Step 8:
443 can be fit into 1338 3 times, resulting in a remainder of 9.
The number 3 becomes the next digit in our result. 
Result so far: 70853.0
If we subtract 1329 from 1338, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 9:
When dividing 90 by 443, we get 0 with a remainder of 90.
Write down 0 as next digit of the result. 
Result so far: 70853.0
Subtract 0 from 90 to get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Moving on to step 10:
When dividing 900 by 443, we get 2 with a remainder of 14.
Use 2 as the next digit of our solution. 
Result so far: 70853.02
Subtract 886 from 900 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 11:
140 divided by 443 is 0 with a remainder of 140.
The next digit of our result is 0. 
Result so far: 70853.02
If we subtract 0 from 140, we get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Going ahead to step 12:
443 goes into 1400 3 times with a remainder of 71.
Use 3 as the next digit of our solution. 
Result so far: 70853.0203
Subtract 1329 from 1400 to get 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Moving on to step 13:
443 can be fit into 710 1 times, resulting in a remainder of 267.
The next digit of our result is 1. 
Result so far: 70853.02031
Subtract 443 from 710 to get 267.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2670, and continue the process.

On to step 14:
443 goes into 2670 6 times with a remainder of 12.
Write down 6 as next digit of the result. 
Result so far: 70853.020316
If we subtract 2658 from 2670, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 15:
The number 443 fits into 120 0 times, leaving a remainder of 120.
The number 0 becomes the next digit in our result. 
Result so far: 70853.020316
Subtract 0 from 120 to get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Going ahead to step 16:
When dividing 1200 by 443, we get 2 with a remainder of 314.
Record the quotient 2 as the next digit in the result. 
Result so far: 70853.02031602
If we take 886 away from 1200, we end up with 314.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3140, and continue the process.

The final result is 70853.02031602 with a remainder of 3.14e-07.
