We look at the division of 68507172 by 155 
We're looking to find how many times 155 goes into 68507172.

Step 1:
When dividing 6 by 155, we get 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Grab the next digit (8) from the dividend, add it to 6, then carry on: 68 / 155

On to step 2:
155 goes into 68 0 times with a remainder of 68.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 68, we get 68.
Bring next digit (5) of the dividend behind the 68 and repeat the process: 685 / 155

Let's proceed to step 3:
When dividing 685 by 155, we get 4 with a remainder of 65.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Subtracting 620 from 685 leaves us with 65.
Append the next digit (0) from the dividend to 65 and continue with: 650 / 155

On to step 4:
650 divided by 155 is 4 with a remainder of 30.
The number 4 becomes the next digit in our result. 
Result so far: 44.0
Deduct 620 from 650 and we're left with 30.
Append the next digit (7) from the dividend to 30 and continue with: 307 / 155

Advancing to step 5:
155 can be fit into 307 1 times, resulting in a remainder of 152.
The number 1 becomes the next digit in our result. 
Result so far: 441.0
If we subtract 155 from 307, we get 152.
Take the next digit (1) from the dividend and append it to 152, then repeat: 1521 / 155

Let's proceed to step 6:
When dividing 1521 by 155, we get 9 with a remainder of 126.
The next digit of our result is 9. 
Result so far: 4419.0
Subtracting 1395 from 1521 leaves us with 126.
Bring next digit (7) of the dividend behind the 126 and repeat the process: 1267 / 155

Going ahead to step 7:
If we divide 1267 by 155, we get 8 and a remainder of 27.
Record the quotient 8 as the next digit in the result. 
Result so far: 44198.0
If we take 1240 away from 1267, we end up with 27.
Fetch the next digit (2) from the dividend, attach it to 27 and continue: 272 / 155

Advancing to step 8:
272 divided by 155 is 1 with a remainder of 117.
Use 1 as the next digit of our solution. 
Result so far: 441981.0
If we subtract 155 from 272, we get 117.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1170, and continue the process.

On to step 9:
When dividing 1170 by 155, we get 7 with a remainder of 85.
Put 7 as the next digit of the answer. 
Result so far: 441981.7
If we subtract 1085 from 1170, we get 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Moving on to step 10:
850 divided by 155 is 5 with a remainder of 75.
Write down 5 as next digit of the result. 
Result so far: 441981.75
Subtracting 775 from 850 leaves us with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

On to step 11:
155 can be fit into 750 4 times, resulting in a remainder of 130.
Use 4 as the next digit of our solution. 
Result so far: 441981.754
The remainder is 130 after subtracting 620 from 750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Let's proceed to step 12:
When dividing 1300 by 155, we get 8 with a remainder of 60.
Put 8 as the next digit of the answer. 
Result so far: 441981.7548
If we subtract 1240 from 1300, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 13:
When dividing 600 by 155, we get 3 with a remainder of 135.
The number 3 becomes the next digit in our result. 
Result so far: 441981.75483
Subtract 465 from 600 to get 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

Advancing to step 14:
1350 divided by 155 is 8 with a remainder of 110.
The next digit of our result is 8. 
Result so far: 441981.754838
Subtract 1240 from 1350 to get 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Moving on to step 15:
The number 155 fits into 1100 7 times, leaving a remainder of 15.
The next digit of our result is 7. 
Result so far: 441981.7548387
The remainder is 15 after subtracting 1085 from 1100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 16:
The number 155 fits into 150 0 times, leaving a remainder of 150.
Use 0 as the next digit of our solution. 
Result so far: 441981.7548387
Subtracting 0 from 150 leaves us with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Our division results in 441981.7548387 with a remaining 1.5e-07.
