56398866 ÷ 172 
We're looking to find how many times 172 goes into 56398866.

Advancing to step 1:
5 divided by 172 is 0 with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Take the next digit (6) from the dividend and append it to 5, then repeat: 56 / 172

Moving on to step 2:
If we divide 56 by 172, we get 0 and a remainder of 56.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 56, we get 56.
Grab the next digit (3) from the dividend, add it to 56, then carry on: 563 / 172

Step 3:
When dividing 563 by 172, we get 3 with a remainder of 47.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we take 516 away from 563, we end up with 47.
Append the next digit (9) from the dividend to 47 and continue with: 479 / 172

Advancing to step 4:
If we divide 479 by 172, we get 2 and a remainder of 135.
Use 2 as the next digit of our solution. 
Result so far: 32.0
Subtract 344 from 479 to get 135.
Include the next digit (8) from the dividend after 135, then repeat: 1358 / 172

Advancing to step 5:
172 can be fit into 1358 7 times, resulting in a remainder of 154.
The number 7 becomes the next digit in our result. 
Result so far: 327.0
Subtract 1204 from 1358 to get 154.
Take the next digit (8) from the dividend and append it to 154, then repeat: 1548 / 172

Moving on to step 6:
172 goes into 1548 9 times with a remainder of 0.
Put 9 as the next digit of the answer. 
Result so far: 3279.0
The remainder is 0 after subtracting 1548 from 1548.
Take the next digit (6) from the dividend and append it to 0, then repeat: 6 / 172

Moving on to step 7:
The number 172 fits into 6 0 times, leaving a remainder of 6.
The next digit of our result is 0. 
Result so far: 32790.0
Subtract 0 from 6 to get 6.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 172

Moving on to step 8:
172 can be fit into 66 0 times, resulting in a remainder of 66.
Write down 0 as next digit of the result. 
Result so far: 327900.0
If we subtract 0 from 66, we get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Advancing to step 9:
172 can be fit into 660 3 times, resulting in a remainder of 144.
Put 3 as the next digit of the answer. 
Result so far: 327900.3
Deduct 516 from 660 and we're left with 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Step 10:
If we divide 1440 by 172, we get 8 and a remainder of 64.
Write down 8 as next digit of the result. 
Result so far: 327900.38
Subtracting 1376 from 1440 leaves us 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.

Let's proceed to step 11:
If we divide 640 by 172, we get 3 and a remainder of 124.
Record the quotient 3 as the next digit in the result. 
Result so far: 327900.383
Subtracting 516 from 640 leaves us with 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

On to step 12:
1240 divided by 172 is 7 with a remainder of 36.
Use 7 as the next digit of our solution. 
Result so far: 327900.3837
If we subtract 1204 from 1240, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 13:
172 can be fit into 360 2 times, resulting in a remainder of 16.
Use 2 as the next digit of our solution. 
Result so far: 327900.38372
The remainder is 16 after subtracting 344 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 14:
160 divided by 172 is 0 with a remainder of 160.
The next digit of our result is 0. 
Result so far: 327900.38372
If we take 0 away from 160, we end up with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Let's proceed to step 15:
1600 divided by 172 is 9 with a remainder of 52.
The number 9 becomes the next digit in our result. 
Result so far: 327900.3837209
Subtract 1548 from 1600 to get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Going ahead to step 16:
172 can be fit into 520 3 times, resulting in a remainder of 4.
Use 3 as the next digit of our solution. 
Result so far: 327900.38372093
If we subtract 516 from 520, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The final result is 327900.38372093 with a remainder of 4e-09.
