51603408 ÷ 878 
The aim is to understand the frequency of 878 in 51603408.

Advancing to step 1:
878 goes into 5 0 times with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Bring next digit (1) of the dividend behind the 5 and repeat the process: 51 / 878

Step 2:
878 can be fit into 51 0 times, resulting in a remainder of 51.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 51, we end up with 51.
Include the next digit (6) from the dividend after 51, then repeat: 516 / 878

Step 3:
If we divide 516 by 878, we get 0 and a remainder of 516.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 516 leaves us with 516.
Take the next digit (0) from the dividend and append it to 516, then repeat: 5160 / 878

Step 4:
5160 divided by 878 is 5 with a remainder of 770.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Subtracting 4390 from 5160 leaves us with 770.
Bring next digit (3) of the dividend behind the 770 and repeat the process: 7703 / 878

Let's proceed to step 5:
The number 878 fits into 7703 8 times, leaving a remainder of 679.
Write down 8 as next digit of the result. 
Result so far: 58.0
Subtract 7024 from 7703 to get 679.
Take the next digit (4) from the dividend and append it to 679, then repeat: 6794 / 878

Advancing to step 6:
If we divide 6794 by 878, we get 7 and a remainder of 648.
The next digit of our result is 7. 
Result so far: 587.0
Subtract 6146 from 6794 to get 648.
Take the next digit (0) from the dividend and append it to 648, then repeat: 6480 / 878

Let's proceed to step 7:
The number 878 fits into 6480 7 times, leaving a remainder of 334.
The next digit of our result is 7. 
Result so far: 5877.0
If we subtract 6146 from 6480, we get 334.
Grab the next digit (8) from the dividend, add it to 334, then carry on: 3348 / 878

Let's proceed to step 8:
The number 878 fits into 3348 3 times, leaving a remainder of 714.
Record the quotient 3 as the next digit in the result. 
Result so far: 58773.0
Deduct 2634 from 3348 and we're left with 714.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7140, and continue the process.

Moving on to step 9:
7140 divided by 878 is 8 with a remainder of 116.
Use 8 as the next digit of our solution. 
Result so far: 58773.8
Subtracting 7024 from 7140 leaves us with 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Advancing to step 10:
1160 divided by 878 is 1 with a remainder of 282.
The next digit of our result is 1. 
Result so far: 58773.81
Deduct 878 from 1160 and we're left with 282.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2820, and continue the process.

Step 11:
If we divide 2820 by 878, we get 3 and a remainder of 186.
Record the quotient 3 as the next digit in the result. 
Result so far: 58773.813
Subtracting 2634 from 2820 leaves us with 186.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

Step 12:
878 goes into 1860 2 times with a remainder of 104.
Use 2 as the next digit of our solution. 
Result so far: 58773.8132
Subtract 1756 from 1860 to get 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Moving on to step 13:
The number 878 fits into 1040 1 times, leaving a remainder of 162.
The number 1 becomes the next digit in our result. 
Result so far: 58773.81321
Subtract 878 from 1040 to get 162.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1620, and continue the process.

Moving on to step 14:
If we divide 1620 by 878, we get 1 and a remainder of 742.
Write down 1 as next digit of the result. 
Result so far: 58773.813211
Deduct 878 from 1620 and we're left with 742.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7420, and continue the process.

The quotient of the division is 58773.813211, and the remainder is 7.42e-05.
