We look at the division of 55687641 by 172 
We want to figure out the number of times 55687641 can be divided by 172.

Let's proceed to step 1:
172 can be fit into 5 0 times, resulting in a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Take the next digit (5) from the dividend and append it to 5, then repeat: 55 / 172

Step 2:
The number 172 fits into 55 0 times, leaving a remainder of 55.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 55 after subtracting 0 from 55.
Grab the next digit (6) from the dividend, add it to 55, then carry on: 556 / 172

Advancing to step 3:
If we divide 556 by 172, we get 3 and a remainder of 40.
The next digit of our result is 3. 
Result so far: 3.0
Subtract 516 from 556 to get 40.
Grab the next digit (8) from the dividend, add it to 40, then carry on: 408 / 172

Advancing to step 4:
172 can be fit into 408 2 times, resulting in a remainder of 64.
Write down 2 as next digit of the result. 
Result so far: 32.0
The remainder is 64 after subtracting 344 from 408.
Fetch the next digit (7) from the dividend, attach it to 64 and continue: 647 / 172

Let's proceed to step 5:
647 divided by 172 is 3 with a remainder of 131.
Use 3 as the next digit of our solution. 
Result so far: 323.0
Subtracting 516 from 647 leaves us with 131.
Fetch the next digit (6) from the dividend, attach it to 131 and continue: 1316 / 172

Let's proceed to step 6:
The number 172 fits into 1316 7 times, leaving a remainder of 112.
Put 7 as the next digit of the answer. 
Result so far: 3237.0
If we subtract 1204 from 1316, we get 112.
Fetch the next digit (4) from the dividend, attach it to 112 and continue: 1124 / 172

Step 7:
1124 divided by 172 is 6 with a remainder of 92.
Write down 6 as next digit of the result. 
Result so far: 32376.0
Subtract 1032 from 1124 to get 92.
Append the next digit (1) from the dividend to 92 and continue with: 921 / 172

Moving on to step 8:
If we divide 921 by 172, we get 5 and a remainder of 61.
Record the quotient 5 as the next digit in the result. 
Result so far: 323765.0
Deduct 860 from 921 and we're left 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.

Going ahead to step 9:
If we divide 610 by 172, we get 3 and a remainder of 94.
Put 3 as the next digit of the answer. 
Result so far: 323765.3
Subtract 516 from 610 to get 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Moving on to step 10:
When dividing 940 by 172, we get 5 with a remainder of 80.
The next digit of our result is 5. 
Result so far: 323765.35
If we subtract 860 from 940, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Let's proceed to step 11:
If we divide 800 by 172, we get 4 and a remainder of 112.
Put 4 as the next digit of the answer. 
Result so far: 323765.354
The remainder is 112 after subtracting 688 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Step 12:
When dividing 1120 by 172, we get 6 with a remainder of 88.
The next digit of our result is 6. 
Result so far: 323765.3546
Subtract 1032 from 1120 to get 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Step 13:
172 goes into 880 5 times with a remainder of 20.
The next digit of our result is 5. 
Result so far: 323765.35465
Subtracting 860 from 880 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 14:
If we divide 200 by 172, we get 1 and a remainder of 28.
Use 1 as the next digit of our solution. 
Result so far: 323765.354651
Subtracting 172 from 200 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 15:
When dividing 280 by 172, we get 1 with a remainder of 108.
Use 1 as the next digit of our solution. 
Result so far: 323765.3546511
Subtracting 172 from 280 leaves us with 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

The final outcome is 323765.3546511, with a leftover of 1.08e-06.
