172120 divided by 67 
We're looking to find how many times 67 goes into 172120.

Step 1:
When dividing 1 by 67, we get 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Grab the next digit (7) from the dividend, add it to 1, then carry on: 17 / 67

Moving on to step 2:
67 can be fit into 17 0 times, resulting in a remainder of 17.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 17 leaves us with 17.
Fetch the next digit (2) from the dividend, attach it to 17 and continue: 172 / 67

Advancing to step 3:
67 goes into 172 2 times with a remainder of 38.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtracting 134 from 172 leaves us with 38.
Grab the next digit (1) from the dividend, add it to 38, then carry on: 381 / 67

Advancing to step 4:
The number 67 fits into 381 5 times, leaving a remainder of 46.
Put 5 as the next digit of the answer. 
Result so far: 25.0
The remainder is 46 after subtracting 335 from 381.
Fetch the next digit (2) from the dividend, attach it to 46 and continue: 462 / 67

Advancing to step 5:
67 can be fit into 462 6 times, resulting in a remainder of 60.
The number 6 becomes the next digit in our result. 
Result so far: 256.0
Subtracting 402 from 462 leaves us with 60.
Include the next digit (0) from the dividend after 60, then repeat: 600 / 67

Moving on to step 6:
67 goes into 600 8 times with a remainder of 64.
Record the quotient 8 as the next digit in the result. 
Result so far: 2568.0
The remainder is 64 after subtracting 536 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 7:
When dividing 640 by 67, we get 9 with a remainder of 37.
The next digit of our result is 9. 
Result so far: 2568.9
Deduct 603 from 640 and we're left with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

On to step 8:
If we divide 370 by 67, we get 5 and a remainder of 35.
The next digit of our result is 5. 
Result so far: 2568.95
The remainder is 35 after subtracting 335 from 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

On to step 9:
When dividing 350 by 67, we get 5 with a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 2568.955
Subtracting 335 from 350 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

After the division, we end up with 2568.955 and a remainder of 0.0015.
