We're dividing 53878700 by 711 
The aim is to understand the frequency of 711 in 53878700.

Going ahead to step 1:
5 divided by 711 is 0 with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Fetch the next digit (3) from the dividend, attach it to 5 and continue: 53 / 711

Let's proceed to step 2:
When dividing 53 by 711, we get 0 with a remainder of 53.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 53 leaves us with 53.
Bring next digit (8) of the dividend behind the 53 and repeat the process: 538 / 711

Moving on to step 3:
When dividing 538 by 711, we get 0 with a remainder of 538.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 538, we end up with 538.
Bring next digit (7) of the dividend behind the 538 and repeat the process: 5387 / 711

Going ahead to step 4:
711 goes into 5387 7 times with a remainder of 410.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
If we take 4977 away from 5387, we end up with 410.
Take the next digit (8) from the dividend and append it to 410, then repeat: 4108 / 711

On to step 5:
711 goes into 4108 5 times with a remainder of 553.
Put 5 as the next digit of the answer. 
Result so far: 75.0
Subtract 3555 from 4108 to get 553.
Bring next digit (7) of the dividend behind the 553 and repeat the process: 5537 / 711

Going ahead to step 6:
The number 711 fits into 5537 7 times, leaving a remainder of 560.
Write down 7 as next digit of the result. 
Result so far: 757.0
Subtract 4977 from 5537 to get 560.
Bring next digit (0) of the dividend behind the 560 and repeat the process: 5600 / 711

On to step 7:
711 can be fit into 5600 7 times, resulting in a remainder of 623.
Use 7 as the next digit of our solution. 
Result so far: 7577.0
If we subtract 4977 from 5600, we get 623.
Take the next digit (0) from the dividend and append it to 623, then repeat: 6230 / 711

Step 8:
711 can be fit into 6230 8 times, resulting in a remainder of 542.
Use 8 as the next digit of our solution. 
Result so far: 75778.0
Deduct 5688 from 6230 and we're left with 542.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5420, and continue the process.

On to step 9:
When dividing 5420 by 711, we get 7 with a remainder of 443.
The next digit of our result is 7. 
Result so far: 75778.7
The remainder is 443 after subtracting 4977 from 5420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4430, and continue the process.

Going ahead to step 10:
711 goes into 4430 6 times with a remainder of 164.
Record the quotient 6 as the next digit in the result. 
Result so far: 75778.76
Subtracting 4266 from 4430 leaves us with 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

On to step 11:
711 goes into 1640 2 times with a remainder of 218.
Use 2 as the next digit of our solution. 
Result so far: 75778.762
Subtract 1422 from 1640 to get 218.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2180, and continue the process.

Going ahead to step 12:
If we divide 2180 by 711, we get 3 and a remainder of 47.
Put 3 as the next digit of the answer. 
Result so far: 75778.7623
Subtract 2133 from 2180 to get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Moving on to step 13:
The number 711 fits into 470 0 times, leaving a remainder of 470.
Put 0 as the next digit of the answer. 
Result so far: 75778.7623
If we subtract 0 from 470, we get 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4700, and continue the process.

Going ahead to step 14:
711 can be fit into 4700 6 times, resulting in a remainder of 434.
Put 6 as the next digit of the answer. 
Result so far: 75778.762306
If we subtract 4266 from 4700, we get 434.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4340, and continue the process.

On to step 15:
If we divide 4340 by 711, we get 6 and a remainder of 74.
Put 6 as the next digit of the answer. 
Result so far: 75778.7623066
The remainder is 74 after subtracting 4266 from 4340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

After the division, we end up with 75778.7623066 and a remainder of 7.4e-07.
