Let's divide 30691070 by 172
Let's see how many times 172 fits into 30691070.

On to step 1:
172 goes into 3 0 times with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Take the next digit (0) from the dividend and append it to 3, then repeat: 30 / 172

Going ahead to step 2:
When dividing 30 by 172, we get 0 with a remainder of 30.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 30 after subtracting 0 from 30.
Bring next digit (6) of the dividend behind the 30 and repeat the process: 306 / 172

Step 3:
172 goes into 306 1 times with a remainder of 134.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 172 away from 306, we end up with 134.
Grab the next digit (9) from the dividend, add it to 134, then carry on: 1349 / 172

Advancing to step 4:
172 goes into 1349 7 times with a remainder of 145.
Record the quotient 7 as the next digit in the result. 
Result so far: 17.0
Subtract 1204 from 1349 to get 145.
Bring next digit (1) of the dividend behind the 145 and repeat the process: 1451 / 172

Going ahead to step 5:
When dividing 1451 by 172, we get 8 with a remainder of 75.
The next digit of our result is 8. 
Result so far: 178.0
If we take 1376 away from 1451, we end up with 75.
Take the next digit (0) from the dividend and append it to 75, then repeat: 750 / 172

Going ahead to step 6:
The number 172 fits into 750 4 times, leaving a remainder of 62.
Put 4 as the next digit of the answer. 
Result so far: 1784.0
Deduct 688 from 750 and we're left with 62.
Bring next digit (7) of the dividend behind the 62 and repeat the process: 627 / 172

Going ahead to step 7:
172 can be fit into 627 3 times, resulting in a remainder of 111.
Use 3 as the next digit of our solution. 
Result so far: 17843.0
Subtracting 516 from 627 leaves us with 111.
Append the next digit (0) from the dividend to 111 and continue with: 1110 / 172

Advancing to step 8:
The number 172 fits into 1110 6 times, leaving a remainder of 78.
The number 6 becomes the next digit in our result. 
Result so far: 178436.0
Deduct 1032 from 1110 and we're left with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Going ahead to step 9:
When dividing 780 by 172, we get 4 with a remainder of 92.
Record the quotient 4 as the next digit in the result. 
Result so far: 178436.4
Deduct 688 from 780 and we're left with 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Moving on to step 10:
172 goes into 920 5 times with a remainder of 60.
The next digit of our result is 5. 
Result so far: 178436.45
Subtracting 860 from 920 leaves us 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.

Advancing to step 11:
600 divided by 172 is 3 with a remainder of 84.
Write down 3 as next digit of the result. 
Result so far: 178436.453
If we subtract 516 from 600, we get 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Moving on to step 12:
The number 172 fits into 840 4 times, leaving a remainder of 152.
The number 4 becomes the next digit in our result. 
Result so far: 178436.4534
If we take 688 away from 840, we end up with 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

On to step 13:
1520 divided by 172 is 8 with a remainder of 144.
Use 8 as the next digit of our solution. 
Result so far: 178436.45348
The remainder is 144 after subtracting 1376 from 1520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Step 14:
If we divide 1440 by 172, we get 8 and a remainder of 64.
The next digit of our result is 8. 
Result so far: 178436.453488
If we take 1376 away from 1440, we end up with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

The quotient of the division is 178436.453488, and the remainder is 6.4e-06.
