We look at the division of 37887007 by 699 
The aim is to understand the frequency of 699 in 37887007.

On to step 1:
699 can be fit into 3 0 times, resulting in a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Include the next digit (7) from the dividend after 3, then repeat: 37 / 699

Let's proceed to step 2:
If we divide 37 by 699, we get 0 and a remainder of 37.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 37, we get 37.
Include the next digit (8) from the dividend after 37, then repeat: 378 / 699

Moving on to step 3:
When dividing 378 by 699, we get 0 with a remainder of 378.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 378 and we're left with 378.
Grab the next digit (8) from the dividend, add it to 378, then carry on: 3788 / 699

Moving on to step 4:
699 can be fit into 3788 5 times, resulting in a remainder of 293.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
The remainder is 293 after subtracting 3495 from 3788.
Append the next digit (7) from the dividend to 293 and continue with: 2937 / 699

Advancing to step 5:
2937 divided by 699 is 4 with a remainder of 141.
Put 4 as the next digit of the answer. 
Result so far: 54.0
Deduct 2796 from 2937 and we're left with 141.
Take the next digit (0) from the dividend and append it to 141, then repeat: 1410 / 699

Moving on to step 6:
The number 699 fits into 1410 2 times, leaving a remainder of 12.
Put 2 as the next digit of the answer. 
Result so far: 542.0
If we subtract 1398 from 1410, we get 12.
Grab the next digit (0) from the dividend, add it to 12, then carry on: 120 / 699

On to step 7:
If we divide 120 by 699, we get 0 and a remainder of 120.
Use 0 as the next digit of our solution. 
Result so far: 5420.0
If we take 0 away from 120, we end up with 120.
Take the next digit (7) from the dividend and append it to 120, then repeat: 1207 / 699

Let's proceed to step 8:
1207 divided by 699 is 1 with a remainder of 508.
The next digit of our result is 1. 
Result so far: 54201.0
If we take 699 away from 1207, we end up with 508.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5080, and continue the process.

Moving on to step 9:
5080 divided by 699 is 7 with a remainder of 187.
Put 7 as the next digit of the answer. 
Result so far: 54201.7
The remainder is 187 after subtracting 4893 from 5080.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1870, and continue the process.

Going ahead to step 10:
The number 699 fits into 1870 2 times, leaving a remainder of 472.
Record the quotient 2 as the next digit in the result. 
Result so far: 54201.72
The remainder is 472 after subtracting 1398 from 1870.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4720, and continue the process.

On to step 11:
4720 divided by 699 is 6 with a remainder of 526.
Write down 6 as next digit of the result. 
Result so far: 54201.726
Subtracting 4194 from 4720 leaves us with 526.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5260, and continue the process.

Moving on to step 12:
699 goes into 5260 7 times with a remainder of 367.
Write down 7 as next digit of the result. 
Result so far: 54201.7267
The remainder is 367 after subtracting 4893 from 5260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3670, and continue the process.

Let's proceed to step 13:
If we divide 3670 by 699, we get 5 and a remainder of 175.
Use 5 as the next digit of our solution. 
Result so far: 54201.72675
Subtracting 3495 from 3670 leaves us with 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

Let's proceed to step 14:
The number 699 fits into 1750 2 times, leaving a remainder of 352.
The next digit of our result is 2. 
Result so far: 54201.726752
The remainder is 352 after subtracting 1398 from 1750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

Let's proceed to step 15:
When dividing 3520 by 699, we get 5 with a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 54201.7267525
If we take 3495 away from 3520, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Let's proceed to step 16:
When dividing 250 by 699, we get 0 with a remainder of 250.
The next digit of our result is 0. 
Result so far: 54201.7267525
The remainder is 250 after subtracting 0 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

The final result is 54201.7267525 with a remainder of 2.5e-07.
