Let's divide 75603171 by 155
We want to figure out the number of times 75603171 can be divided by 155.

Going ahead to step 1:
155 can be fit into 7 0 times, resulting in a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Include the next digit (5) from the dividend after 7, then repeat: 75 / 155

Going ahead to step 2:
The number 155 fits into 75 0 times, leaving a remainder of 75.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 75, we get 75.
Append the next digit (6) from the dividend to 75 and continue with: 756 / 155

On to step 3:
The number 155 fits into 756 4 times, leaving a remainder of 136.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Deduct 620 from 756 and we're left with 136.
Bring next digit (0) of the dividend behind the 136 and repeat the process: 1360 / 155

On to step 4:
155 goes into 1360 8 times with a remainder of 120.
Record the quotient 8 as the next digit in the result. 
Result so far: 48.0
Subtracting 1240 from 1360 leaves us with 120.
Take the next digit (3) from the dividend and append it to 120, then repeat: 1203 / 155

Going ahead to step 5:
155 goes into 1203 7 times with a remainder of 118.
Use 7 as the next digit of our solution. 
Result so far: 487.0
Deduct 1085 from 1203 and we're left with 118.
Bring next digit (1) of the dividend behind the 118 and repeat the process: 1181 / 155

Step 6:
155 can be fit into 1181 7 times, resulting in a remainder of 96.
The next digit of our result is 7. 
Result so far: 4877.0
Deduct 1085 from 1181 and we're left with 96.
Bring next digit (7) of the dividend behind the 96 and repeat the process: 967 / 155

Going ahead to step 7:
When dividing 967 by 155, we get 6 with a remainder of 37.
Write down 6 as next digit of the result. 
Result so far: 48776.0
Deduct 930 from 967 and we're left with 37.
Append the next digit (1) from the dividend to 37 and continue with: 371 / 155

Going ahead to step 8:
155 goes into 371 2 times with a remainder of 61.
The number 2 becomes the next digit in our result. 
Result so far: 487762.0
If we take 310 away from 371, we end up with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Let's proceed to step 9:
The number 155 fits into 610 3 times, leaving a remainder of 145.
Record the quotient 3 as the next digit in the result. 
Result so far: 487762.3
Subtract 465 from 610 to get 145.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

Advancing to step 10:
155 goes into 1450 9 times with a remainder of 55.
The next digit of our result is 9. 
Result so far: 487762.39
Subtracting 1395 from 1450 leaves us with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Let's proceed to step 11:
550 divided by 155 is 3 with a remainder of 85.
Write down 3 as next digit of the result. 
Result so far: 487762.393
Subtract 465 from 550 to 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 12:
When dividing 850 by 155, we get 5 with a remainder of 75.
The next digit of our result is 5. 
Result so far: 487762.3935
Subtract 775 from 850 to get 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 13:
155 goes into 750 4 times with a remainder of 130.
Put 4 as the next digit of the answer. 
Result so far: 487762.39354
If we subtract 620 from 750, we get 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Moving on to step 14:
If we divide 1300 by 155, we get 8 and a remainder of 60.
Put 8 as the next digit of the answer. 
Result so far: 487762.393548
Deduct 1240 from 1300 and we're left 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 15:
155 goes into 600 3 times with a remainder of 135.
Write down 3 as next digit of the result. 
Result so far: 487762.3935483
If we take 465 away from 600, we end up with 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 16:
155 can be fit into 1350 8 times, resulting in a remainder of 110.
The next digit of our result is 8. 
Result so far: 487762.39354838
If we take 1240 away from 1350, we end up with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Our division results in 487762.39354838 with a remaining 1.1e-07.
