51115589 ÷ 177 
The aim is to understand the frequency of 177 in 51115589.

Advancing to step 1:
If we divide 5 by 177, we get 0 and a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Include the next digit (1) from the dividend after 5, then repeat: 51 / 177

Let's proceed to step 2:
If we divide 51 by 177, we get 0 and a remainder of 51.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 51, we get 51.
Fetch the next digit (1) from the dividend, attach it to 51 and continue: 511 / 177

Step 3:
177 can be fit into 511 2 times, resulting in a remainder of 157.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
The remainder is 157 after subtracting 354 from 511.
Include the next digit (1) from the dividend after 157, then repeat: 1571 / 177

Advancing to step 4:
When dividing 1571 by 177, we get 8 with a remainder of 155.
Record the quotient 8 as the next digit in the result. 
Result so far: 28.0
If we subtract 1416 from 1571, we get 155.
Append the next digit (5) from the dividend to 155 and continue with: 1555 / 177

Let's proceed to step 5:
1555 divided by 177 is 8 with a remainder of 139.
The number 8 becomes the next digit in our result. 
Result so far: 288.0
Subtract 1416 from 1555 to get 139.
Grab the next digit (5) from the dividend, add it to 139, then carry on: 1395 / 177

On to step 6:
1395 divided by 177 is 7 with a remainder of 156.
The number 7 becomes the next digit in our result. 
Result so far: 2887.0
Subtract 1239 from 1395 to get 156.
Fetch the next digit (8) from the dividend, attach it to 156 and continue: 1568 / 177

On to step 7:
177 can be fit into 1568 8 times, resulting in a remainder of 152.
The number 8 becomes the next digit in our result. 
Result so far: 28878.0
Subtract 1416 from 1568 to get 152.
Include the next digit (9) from the dividend after 152, then repeat: 1529 / 177

Going ahead to step 8:
The number 177 fits into 1529 8 times, leaving a remainder of 113.
The number 8 becomes the next digit in our result. 
Result so far: 288788.0
Subtracting 1416 from 1529 leaves us with 113.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1130, and continue the process.

Advancing to step 9:
When dividing 1130 by 177, we get 6 with a remainder of 68.
Use 6 as the next digit of our solution. 
Result so far: 288788.6
If we take 1062 away from 1130, we end up with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Going ahead to step 10:
177 goes into 680 3 times with a remainder of 149.
Put 3 as the next digit of the answer. 
Result so far: 288788.63
If we subtract 531 from 680, we get 149.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1490, and continue the process.

Moving on to step 11:
When dividing 1490 by 177, we get 8 with a remainder of 74.
Record the quotient 8 as the next digit in the result. 
Result so far: 288788.638
Subtracting 1416 from 1490 leaves us with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Let's proceed to step 12:
The number 177 fits into 740 4 times, leaving a remainder of 32.
Put 4 as the next digit of the answer. 
Result so far: 288788.6384
The remainder is 32 after subtracting 708 from 740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 13:
The number 177 fits into 320 1 times, leaving a remainder of 143.
Write down 1 as next digit of the result. 
Result so far: 288788.63841
If we subtract 177 from 320, we get 143.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1430, and continue the process.

Moving on to step 14:
The number 177 fits into 1430 8 times, leaving a remainder of 14.
Record the quotient 8 as the next digit in the result. 
Result so far: 288788.638418
Subtract 1416 from 1430 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 15:
If we divide 140 by 177, we get 0 and a remainder of 140.
Record the quotient 0 as the next digit in the result. 
Result so far: 288788.638418
The remainder is 140 after subtracting 0 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Moving on to step 16:
177 can be fit into 1400 7 times, resulting in a remainder of 161.
The next digit of our result is 7. 
Result so far: 288788.63841807
Subtract 1239 from 1400 to get 161.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1610, and continue the process.

The quotient of the division is 288788.63841807, and the remainder is 1.61e-07.
