78271845 ÷ 551 
The aim is to understand the frequency of 551 in 78271845.

Step 1:
551 can be fit into 7 0 times, resulting in a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Grab the next digit (8) from the dividend, add it to 7, then carry on: 78 / 551

Advancing to step 2:
551 goes into 78 0 times with a remainder of 78.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 78 to get 78.
Fetch the next digit (2) from the dividend, attach it to 78 and continue: 782 / 551

Step 3:
551 can be fit into 782 1 times, resulting in a remainder of 231.
The next digit of our result is 1. 
Result so far: 1.0
If we take 551 away from 782, we end up with 231.
Include the next digit (7) from the dividend after 231, then repeat: 2317 / 551

Going ahead to step 4:
551 goes into 2317 4 times with a remainder of 113.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
Subtracting 2204 from 2317 leaves us with 113.
Take the next digit (1) from the dividend and append it to 113, then repeat: 1131 / 551

Let's proceed to step 5:
551 goes into 1131 2 times with a remainder of 29.
Record the quotient 2 as the next digit in the result. 
Result so far: 142.0
Subtracting 1102 from 1131 leaves us with 29.
Grab the next digit (8) from the dividend, add it to 29, then carry on: 298 / 551

Step 6:
551 goes into 298 0 times with a remainder of 298.
The next digit of our result is 0. 
Result so far: 1420.0
If we take 0 away from 298, we end up with 298.
Grab the next digit (4) from the dividend, add it to 298, then carry on: 2984 / 551

Step 7:
If we divide 2984 by 551, we get 5 and a remainder of 229.
Put 5 as the next digit of the answer. 
Result so far: 14205.0
Deduct 2755 from 2984 and we're left with 229.
Include the next digit (5) from the dividend after 229, then repeat: 2295 / 551

Advancing to step 8:
The number 551 fits into 2295 4 times, leaving a remainder of 91.
Record the quotient 4 as the next digit in the result. 
Result so far: 142054.0
Subtract 2204 from 2295 to get 91.
Since there are no more digits in the dividend, we add a zero to the remainder making it 910, and continue the process.

Going ahead to step 9:
910 divided by 551 is 1 with a remainder of 359.
The number 1 becomes the next digit in our result. 
Result so far: 142054.1
Subtract 551 from 910 to get 359.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3590, and continue the process.

Advancing to step 10:
3590 divided by 551 is 6 with a remainder of 284.
Put 6 as the next digit of the answer. 
Result so far: 142054.16
If we take 3306 away from 3590, we end up with 284.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2840, and continue the process.

Let's proceed to step 11:
2840 divided by 551 is 5 with a remainder of 85.
The number 5 becomes the next digit in our result. 
Result so far: 142054.165
If we subtract 2755 from 2840, we get 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Going ahead to step 12:
The number 551 fits into 850 1 times, leaving a remainder of 299.
The next digit of our result is 1. 
Result so far: 142054.1651
If we subtract 551 from 850, we get 299.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2990, and continue the process.

Step 13:
The number 551 fits into 2990 5 times, leaving a remainder of 235.
Put 5 as the next digit of the answer. 
Result so far: 142054.16515
Subtract 2755 from 2990 to get 235.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2350, and continue the process.

Step 14:
551 goes into 2350 4 times with a remainder of 146.
Put 4 as the next digit of the answer. 
Result so far: 142054.165154
If we subtract 2204 from 2350, we get 146.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

Going ahead to step 15:
551 goes into 1460 2 times with a remainder of 358.
Write down 2 as next digit of the result. 
Result so far: 142054.1651542
The remainder is 358 after subtracting 1102 from 1460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3580, and continue the process.

Going ahead to step 16:
The number 551 fits into 3580 6 times, leaving a remainder of 274.
Put 6 as the next digit of the answer. 
Result so far: 142054.16515426
If we take 3306 away from 3580, we end up with 274.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2740, and continue the process.

Our division results in 142054.16515426 with a remaining 2.74e-07.
