31588353 ÷ 807 
We want to figure out the number of times 31588353 can be divided by 807.

Step 1:
When dividing 3 by 807, we get 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Fetch the next digit (1) from the dividend, attach it to 3 and continue: 31 / 807

Advancing to step 2:
807 goes into 31 0 times with a remainder of 31.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 31 and we're left with 31.
Take the next digit (5) from the dividend and append it to 31, then repeat: 315 / 807

On to step 3:
When dividing 315 by 807, we get 0 with a remainder of 315.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 315 and we're left with 315.
Include the next digit (8) from the dividend after 315, then repeat: 3158 / 807

Going ahead to step 4:
If we divide 3158 by 807, we get 3 and a remainder of 737.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Deduct 2421 from 3158 and we're left with 737.
Include the next digit (8) from the dividend after 737, then repeat: 7378 / 807

Advancing to step 5:
7378 divided by 807 is 9 with a remainder of 115.
Record the quotient 9 as the next digit in the result. 
Result so far: 39.0
If we subtract 7263 from 7378, we get 115.
Include the next digit (3) from the dividend after 115, then repeat: 1153 / 807

Advancing to step 6:
If we divide 1153 by 807, we get 1 and a remainder of 346.
The next digit of our result is 1. 
Result so far: 391.0
If we take 807 away from 1153, we end up with 346.
Bring next digit (5) of the dividend behind the 346 and repeat the process: 3465 / 807

Going ahead to step 7:
3465 divided by 807 is 4 with a remainder of 237.
Put 4 as the next digit of the answer. 
Result so far: 3914.0
Subtracting 3228 from 3465 leaves us with 237.
Fetch the next digit (3) from the dividend, attach it to 237 and continue: 2373 / 807

Let's proceed to step 8:
807 goes into 2373 2 times with a remainder of 759.
Put 2 as the next digit of the answer. 
Result so far: 39142.0
The remainder is 759 after subtracting 1614 from 2373.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7590, and continue the process.

On to step 9:
7590 divided by 807 is 9 with a remainder of 327.
Use 9 as the next digit of our solution. 
Result so far: 39142.9
Subtract 7263 from 7590 to get 327.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3270, and continue the process.

Let's proceed to step 10:
807 can be fit into 3270 4 times, resulting in a remainder of 42.
Put 4 as the next digit of the answer. 
Result so far: 39142.94
Deduct 3228 from 3270 and we're left with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Step 11:
807 can be fit into 420 0 times, resulting in a remainder of 420.
The next digit of our result is 0. 
Result so far: 39142.94
Subtracting 0 from 420 leaves us with 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

Advancing to step 12:
If we divide 4200 by 807, we get 5 and a remainder of 165.
Record the quotient 5 as the next digit in the result. 
Result so far: 39142.9405
Subtracting 4035 from 4200 leaves us with 165.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

Moving on to step 13:
807 can be fit into 1650 2 times, resulting in a remainder of 36.
Put 2 as the next digit of the answer. 
Result so far: 39142.94052
Subtracting 1614 from 1650 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 14:
The number 807 fits into 360 0 times, leaving a remainder of 360.
The number 0 becomes the next digit in our result. 
Result so far: 39142.94052
Subtracting 0 from 360 leaves us with 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Step 15:
If we divide 3600 by 807, we get 4 and a remainder of 372.
The number 4 becomes the next digit in our result. 
Result so far: 39142.9405204
If we subtract 3228 from 3600, we get 372.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3720, and continue the process.

Step 16:
807 goes into 3720 4 times with a remainder of 492.
Use 4 as the next digit of our solution. 
Result so far: 39142.94052044
Subtracting 3228 from 3720 leaves us with 492.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4920, and continue the process.

The final result is 39142.94052044 with a remainder of 4.92e-07.
