59951793 ÷ 51 
The aim is to understand the frequency of 51 in 59951793.

Moving on to step 1:
The number 51 fits into 5 0 times, leaving a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Append the next digit (9) from the dividend to 5 and continue with: 59 / 51

Advancing to step 2:
When dividing 59 by 51, we get 1 with a remainder of 8.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 51 from 59 and we're left with 8.
Take the next digit (9) from the dividend and append it to 8, then repeat: 89 / 51

Going ahead to step 3:
51 can be fit into 89 1 times, resulting in a remainder of 38.
Put 1 as the next digit of the answer. 
Result so far: 11.0
Deduct 51 from 89 and we're left with 38.
Include the next digit (5) from the dividend after 38, then repeat: 385 / 51

On to step 4:
If we divide 385 by 51, we get 7 and a remainder of 28.
Use 7 as the next digit of our solution. 
Result so far: 117.0
Subtract 357 from 385 to get 28.
Grab the next digit (1) from the dividend, add it to 28, then carry on: 281 / 51

Moving on to step 5:
51 goes into 281 5 times with a remainder of 26.
Record the quotient 5 as the next digit in the result. 
Result so far: 1175.0
If we subtract 255 from 281, we get 26.
Fetch the next digit (7) from the dividend, attach it to 26 and continue: 267 / 51

Advancing to step 6:
267 divided by 51 is 5 with a remainder of 12.
Put 5 as the next digit of the answer. 
Result so far: 11755.0
If we take 255 away from 267, we end up with 12.
Append the next digit (9) from the dividend to 12 and continue with: 129 / 51

Step 7:
129 divided by 51 is 2 with a remainder of 27.
Use 2 as the next digit of our solution. 
Result so far: 117552.0
The remainder is 27 after subtracting 102 from 129.
Grab the next digit (3) from the dividend, add it to 27, then carry on: 273 / 51

Moving on to step 8:
The number 51 fits into 273 5 times, leaving a remainder of 18.
The next digit of our result is 5. 
Result so far: 1175525.0
Subtract 255 from 273 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 9:
180 divided by 51 is 3 with a remainder of 27.
Use 3 as the next digit of our solution. 
Result so far: 1175525.3
Deduct 153 from 180 and we're left with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Advancing to step 10:
51 goes into 270 5 times with a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 1175525.35
Subtracting 255 from 270 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 11:
If we divide 150 by 51, we get 2 and a remainder of 48.
The next digit of our result is 2. 
Result so far: 1175525.352
If we take 102 away from 150, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Let's proceed to step 12:
The number 51 fits into 480 9 times, leaving a remainder of 21.
Use 9 as the next digit of our solution. 
Result so far: 1175525.3529
Subtracting 459 from 480 leaves us with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

On to step 13:
The number 51 fits into 210 4 times, leaving a remainder of 6.
Put 4 as the next digit of the answer. 
Result so far: 1175525.35294
Deduct 204 from 210 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 14:
The number 51 fits into 60 1 times, leaving a remainder of 9.
The number 1 becomes the next digit in our result. 
Result so far: 1175525.352941
Subtract 51 from 60 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 15:
51 can be fit into 90 1 times, resulting in a remainder of 39.
Write down 1 as next digit of the result. 
Result so far: 1175525.3529411
If we subtract 51 from 90, we get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

The final outcome is 1175525.3529411, with a leftover of 3.9e-07.
