We divide 31989388 by 172
We want to figure out the number of times 31989388 can be divided by 172.

Let's proceed to step 1:
When dividing 3 by 172, we get 0 with 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.
Append the next digit (1) from the dividend to 3 and continue with: 31 / 172

Going ahead to step 2:
172 goes into 31 0 times with a remainder of 31.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 31 leaves us with 31.
Fetch the next digit (9) from the dividend, attach it to 31 and continue: 319 / 172

On to step 3:
172 goes into 319 1 times with a remainder of 147.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 147 after subtracting 172 from 319.
Take the next digit (8) from the dividend and append it to 147, then repeat: 1478 / 172

On to step 4:
172 goes into 1478 8 times with a remainder of 102.
Record the quotient 8 as the next digit in the result. 
Result so far: 18.0
The remainder is 102 after subtracting 1376 from 1478.
Grab the next digit (9) from the dividend, add it to 102, then carry on: 1029 / 172

Let's proceed to step 5:
1029 divided by 172 is 5 with a remainder of 169.
Record the quotient 5 as the next digit in the result. 
Result so far: 185.0
Subtracting 860 from 1029 leaves us with 169.
Take the next digit (3) from the dividend and append it to 169, then repeat: 1693 / 172

Going ahead to step 6:
172 goes into 1693 9 times with a remainder of 145.
The number 9 becomes the next digit in our result. 
Result so far: 1859.0
If we take 1548 away from 1693, we end up with 145.
Grab the next digit (8) from the dividend, add it to 145, then carry on: 1458 / 172

Advancing to step 7:
172 goes into 1458 8 times with a remainder of 82.
Write down 8 as next digit of the result. 
Result so far: 18598.0
Deduct 1376 from 1458 and we're left with 82.
Fetch the next digit (8) from the dividend, attach it to 82 and continue: 828 / 172

Let's proceed to step 8:
172 goes into 828 4 times with a remainder of 140.
Use 4 as the next digit of our solution. 
Result so far: 185984.0
If we subtract 688 from 828, 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 9:
When dividing 1400 by 172, we get 8 with a remainder of 24.
Write down 8 as next digit of the result. 
Result so far: 185984.8
The remainder is 24 after subtracting 1376 from 1400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 10:
The number 172 fits into 240 1 times, leaving a remainder of 68.
The number 1 becomes the next digit in our result. 
Result so far: 185984.81
Deduct 172 from 240 and we're left with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Going ahead to step 11:
172 can be fit into 680 3 times, resulting in a remainder of 164.
The next digit of our result is 3. 
Result so far: 185984.813
If we take 516 away from 680, we end up with 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

Moving on to step 12:
The number 172 fits into 1640 9 times, leaving a remainder of 92.
Write down 9 as next digit of the result. 
Result so far: 185984.8139
The remainder is 92 after subtracting 1548 from 1640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Step 13:
If we divide 920 by 172, we get 5 and a remainder of 60.
The number 5 becomes the next digit in our result. 
Result so far: 185984.81395
If we take 860 away from 920, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 14:
The number 172 fits into 600 3 times, leaving a remainder of 84.
Put 3 as the next digit of the answer. 
Result so far: 185984.813953
Deduct 516 from 600 and we're left with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Advancing to step 15:
The number 172 fits into 840 4 times, leaving a remainder of 152.
Use 4 as the next digit of our solution. 
Result so far: 185984.8139534
The remainder is 152 after subtracting 688 from 840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Step 16:
When dividing 1520 by 172, we get 8 with a remainder of 144.
Record the quotient 8 as the next digit in the result. 
Result so far: 185984.81395348
If we take 1376 away from 1520, we end up with 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

The quotient of the division is 185984.81395348, and the remainder is 1.44e-07.
