We divide 31573507 by 39
Our goal is to divide 31573507 by 39.

On to step 1:
When dividing 3 by 39, we get 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Append the next digit (1) from the dividend to 3 and continue with: 31 / 39

Going ahead to step 2:
When dividing 31 by 39, we get 0 with a remainder of 31.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 31, we get 31.
Take the next digit (5) from the dividend and append it to 31, then repeat: 315 / 39

Step 3:
315 divided by 39 is 8 with a remainder of 3.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
If we subtract 312 from 315, we get 3.
Bring next digit (7) of the dividend behind the 3 and repeat the process: 37 / 39

Step 4:
When dividing 37 by 39, we get 0 with a remainder of 37.
The next digit of our result is 0. 
Result so far: 80.0
Deduct 0 from 37 and we're left with 37.
Grab the next digit (3) from the dividend, add it to 37, then carry on: 373 / 39

On to step 5:
373 divided by 39 is 9 with a remainder of 22.
The number 9 becomes the next digit in our result. 
Result so far: 809.0
Deduct 351 from 373 and we're left with 22.
Grab the next digit (5) from the dividend, add it to 22, then carry on: 225 / 39

On to step 6:
The number 39 fits into 225 5 times, leaving a remainder of 30.
Write down 5 as next digit of the result. 
Result so far: 8095.0
Deduct 195 from 225 and we're left with 30.
Grab the next digit (0) from the dividend, add it to 30, then carry on: 300 / 39

On to step 7:
39 goes into 300 7 times with a remainder of 27.
The number 7 becomes the next digit in our result. 
Result so far: 80957.0
If we take 273 away from 300, we end up with 27.
Append the next digit (7) from the dividend to 27 and continue with: 277 / 39

On to step 8:
When dividing 277 by 39, we get 7 with a remainder of 4.
Use 7 as the next digit of our solution. 
Result so far: 809577.0
If we take 273 away from 277, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 9:
If we divide 40 by 39, we get 1 and a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 809577.1
The remainder is 1 after subtracting 39 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 10:
39 can be fit into 10 0 times, resulting in a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 809577.1
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 11:
39 goes into 100 2 times with a remainder of 22.
The next digit of our result is 2. 
Result so far: 809577.102
If we subtract 78 from 100, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 12:
When dividing 220 by 39, we get 5 with a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 809577.1025
Subtracting 195 from 220 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Step 13:
39 can be fit into 250 6 times, resulting in a remainder of 16.
Put 6 as the next digit of the answer. 
Result so far: 809577.10256
Subtract 234 from 250 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 14:
39 can be fit into 160 4 times, resulting in a remainder of 4.
Put 4 as the next digit of the answer. 
Result so far: 809577.102564
The remainder is 4 after subtracting 156 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 15:
40 divided by 39 is 1 with a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 809577.1025641
If we take 39 away from 40, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 16:
39 can be fit into 10 0 times, resulting in a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 809577.1025641
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

After the division, we end up with 809577.1025641 and a remainder of 1e-08.
