42085220 ÷ 551 
The aim is to understand the frequency of 551 in 42085220.

Advancing to step 1:
When dividing 4 by 551, we get 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 551

On to step 2:
551 can be fit into 42 0 times, resulting in a remainder of 42.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 42, we get 42.
Grab the next digit (0) from the dividend, add it to 42, then carry on: 420 / 551

Going ahead to step 3:
If we divide 420 by 551, we get 0 and a remainder of 420.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 420 to get 420.
Include the next digit (8) from the dividend after 420, then repeat: 4208 / 551

Let's proceed to step 4:
The number 551 fits into 4208 7 times, leaving a remainder of 351.
The next digit of our result is 7. 
Result so far: 7.0
Deduct 3857 from 4208 and we're left with 351.
Grab the next digit (5) from the dividend, add it to 351, then carry on: 3515 / 551

On to step 5:
551 goes into 3515 6 times with a remainder of 209.
The next digit of our result is 6. 
Result so far: 76.0
If we take 3306 away from 3515, we end up with 209.
Take the next digit (2) from the dividend and append it to 209, then repeat: 2092 / 551

Going ahead to step 6:
The number 551 fits into 2092 3 times, leaving a remainder of 439.
The next digit of our result is 3. 
Result so far: 763.0
Subtract 1653 from 2092 to get 439.
Include the next digit (2) from the dividend after 439, then repeat: 4392 / 551

Moving on to step 7:
When dividing 4392 by 551, we get 7 with a remainder of 535.
Record the quotient 7 as the next digit in the result. 
Result so far: 7637.0
If we take 3857 away from 4392, we end up with 535.
Fetch the next digit (0) from the dividend, attach it to 535 and continue: 5350 / 551

Step 8:
551 can be fit into 5350 9 times, resulting in a remainder of 391.
The next digit of our result is 9. 
Result so far: 76379.0
Subtracting 4959 from 5350 leaves us with 391.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3910, and continue the process.

Let's proceed to step 9:
When dividing 3910 by 551, we get 7 with a remainder of 53.
The next digit of our result is 7. 
Result so far: 76379.7
If we take 3857 away from 3910, we end up with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Step 10:
When dividing 530 by 551, we get 0 with a remainder of 530.
The number 0 becomes the next digit in our result. 
Result so far: 76379.7
Subtracting 0 from 530 leaves us with 530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5300, and continue the process.

On to step 11:
551 can be fit into 5300 9 times, resulting in a remainder of 341.
The number 9 becomes the next digit in our result. 
Result so far: 76379.709
If we take 4959 away from 5300, we end up with 341.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3410, and continue the process.

Step 12:
551 can be fit into 3410 6 times, resulting in a remainder of 104.
Write down 6 as next digit of the result. 
Result so far: 76379.7096
Deduct 3306 from 3410 and we're left with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

On to step 13:
The number 551 fits into 1040 1 times, leaving a remainder of 489.
Record the quotient 1 as the next digit in the result. 
Result so far: 76379.70961
Subtracting 551 from 1040 leaves us with 489.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4890, and continue the process.

Step 14:
When dividing 4890 by 551, we get 8 with a remainder of 482.
Use 8 as the next digit of our solution. 
Result so far: 76379.709618
If we take 4408 away from 4890, we end up with 482.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4820, and continue the process.

Step 15:
551 goes into 4820 8 times with a remainder of 412.
Write down 8 as next digit of the result. 
Result so far: 76379.7096188
Subtract 4408 from 4820 to get 412.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4120, and continue the process.

In conclusion, the division gives 76379.7096188 with a balance of 4.12e-06.
