Let's divide 39866069 by 172
We want to figure out the number of times 39866069 can be divided by 172.

Going ahead to step 1:
If we divide 3 by 172, we get 0 and a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 172

Let's proceed to step 2:
172 can be fit into 39 0 times, resulting in a remainder of 39.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 39, we end up with 39.
Take the next digit (8) from the dividend and append it to 39, then repeat: 398 / 172

Step 3:
When dividing 398 by 172, we get 2 with a remainder of 54.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Deduct 344 from 398 and we're left with 54.
Bring next digit (6) of the dividend behind the 54 and repeat the process: 546 / 172

Going ahead to step 4:
546 divided by 172 is 3 with a remainder of 30.
The next digit of our result is 3. 
Result so far: 23.0
If we subtract 516 from 546, we get 30.
Grab the next digit (6) from the dividend, add it to 30, then carry on: 306 / 172

Let's proceed to step 5:
306 divided by 172 is 1 with a remainder of 134.
Use 1 as the next digit of our solution. 
Result so far: 231.0
If we take 172 away from 306, we end up with 134.
Grab the next digit (0) from the dividend, add it to 134, then carry on: 1340 / 172

Moving on to step 6:
When dividing 1340 by 172, we get 7 with a remainder of 136.
Record the quotient 7 as the next digit in the result. 
Result so far: 2317.0
Subtracting 1204 from 1340 leaves us with 136.
Include the next digit (6) from the dividend after 136, then repeat: 1366 / 172

Going ahead to step 7:
If we divide 1366 by 172, we get 7 and a remainder of 162.
Put 7 as the next digit of the answer. 
Result so far: 23177.0
The remainder is 162 after subtracting 1204 from 1366.
Bring next digit (9) of the dividend behind the 162 and repeat the process: 1629 / 172

Moving on to step 8:
The number 172 fits into 1629 9 times, leaving a remainder of 81.
Write down 9 as next digit of the result. 
Result so far: 231779.0
Subtract 1548 from 1629 to get 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

On to step 9:
When dividing 810 by 172, we get 4 with a remainder of 122.
Use 4 as the next digit of our solution. 
Result so far: 231779.4
If we subtract 688 from 810, we 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.

Advancing to step 10:
172 can be fit into 1220 7 times, resulting in a remainder of 16.
Write down 7 as next digit of the result. 
Result so far: 231779.47
If we subtract 1204 from 1220, we 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.

On to step 11:
160 divided by 172 is 0 with a remainder of 160.
Use 0 as the next digit of our solution. 
Result so far: 231779.47
Subtracting 0 from 160 leaves us with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Step 12:
1600 divided by 172 is 9 with a remainder of 52.
The next digit of our result is 9. 
Result so far: 231779.4709
If we take 1548 away from 1600, we end up with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

On to step 13:
172 goes into 520 3 times with a remainder of 4.
Record the quotient 3 as the next digit in the result. 
Result so far: 231779.47093
If we take 516 away from 520, 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.

On to step 14:
172 can be fit into 40 0 times, resulting in a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 231779.47093
If we take 0 away from 40, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 15:
When dividing 400 by 172, we get 2 with a remainder of 56.
Write down 2 as next digit of the result. 
Result so far: 231779.4709302
If we subtract 344 from 400, we get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Advancing to step 16:
The number 172 fits into 560 3 times, leaving a remainder of 44.
The number 3 becomes the next digit in our result. 
Result so far: 231779.47093023
The remainder is 44 after subtracting 516 from 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

In conclusion, the division gives 231779.47093023 with a balance of 4.4e-08.
