99816637 divided by 551 
The aim is to understand the frequency of 551 in 99816637.

Step 1:
The number 551 fits into 9 0 times, leaving a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Take the next digit (9) from the dividend and append it to 9, then repeat: 99 / 551

On to step 2:
The number 551 fits into 99 0 times, leaving a remainder of 99.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 99, we get 99.
Bring next digit (8) of the dividend behind the 99 and repeat the process: 998 / 551

Advancing to step 3:
551 goes into 998 1 times with a remainder of 447.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 551 from 998 leaves us with 447.
Append the next digit (1) from the dividend to 447 and continue with: 4471 / 551

Advancing to step 4:
When dividing 4471 by 551, we get 8 with a remainder of 63.
Write down 8 as next digit of the result. 
Result so far: 18.0
Subtracting 4408 from 4471 leaves us with 63.
Include the next digit (6) from the dividend after 63, then repeat: 636 / 551

Going ahead to step 5:
551 goes into 636 1 times with a remainder of 85.
The next digit of our result is 1. 
Result so far: 181.0
If we take 551 away from 636, we end up with 85.
Fetch the next digit (6) from the dividend, attach it to 85 and continue: 856 / 551

Step 6:
When dividing 856 by 551, we get 1 with a remainder of 305.
The next digit of our result is 1. 
Result so far: 1811.0
Subtracting 551 from 856 leaves us with 305.
Grab the next digit (3) from the dividend, add it to 305, then carry on: 3053 / 551

Moving on to step 7:
When dividing 3053 by 551, we get 5 with a remainder of 298.
Write down 5 as next digit of the result. 
Result so far: 18115.0
Deduct 2755 from 3053 and we're left with 298.
Fetch the next digit (7) from the dividend, attach it to 298 and continue: 2987 / 551

Moving on to step 8:
If we divide 2987 by 551, we get 5 and a remainder of 232.
The number 5 becomes the next digit in our result. 
Result so far: 181155.0
If we subtract 2755 from 2987, we get 232.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

Advancing to step 9:
The number 551 fits into 2320 4 times, leaving a remainder of 116.
Write down 4 as next digit of the result. 
Result so far: 181155.4
If we take 2204 away from 2320, we end up 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.

Going ahead to step 10:
551 goes into 1160 2 times with a remainder of 58.
Write down 2 as next digit of the result. 
Result so far: 181155.42
Deduct 1102 from 1160 and we're left with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Advancing to step 11:
If we divide 580 by 551, we get 1 and a remainder of 29.
Use 1 as the next digit of our solution. 
Result so far: 181155.421
If we subtract 551 from 580, we get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Going ahead to step 12:
551 can be fit into 290 0 times, resulting in a remainder of 290.
Use 0 as the next digit of our solution. 
Result so far: 181155.421
If we take 0 away from 290, we end up with 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

On to step 13:
2900 divided by 551 is 5 with a remainder of 145.
Use 5 as the next digit of our solution. 
Result so far: 181155.42105
The remainder is 145 after subtracting 2755 from 2900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

Step 14:
551 can be fit into 1450 2 times, resulting in a remainder of 348.
Put 2 as the next digit of the answer. 
Result so far: 181155.421052
Subtracting 1102 from 1450 leaves us with 348.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3480, and continue the process.

On to step 15:
551 can be fit into 3480 6 times, resulting in a remainder of 174.
Record the quotient 6 as the next digit in the result. 
Result so far: 181155.4210526
If we take 3306 away from 3480, we end up with 174.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1740, and continue the process.

Moving on to step 16:
1740 divided by 551 is 3 with a remainder of 87.
Record the quotient 3 as the next digit in the result. 
Result so far: 181155.42105263
Subtract 1653 from 1740 to get 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

The quotient of the division is 181155.42105263, and the remainder is 8.7e-08.
