15593142 divided by 938 
The aim is to understand the frequency of 938 in 15593142.

Step 1:
When dividing 1 by 938, we get 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 938

Going ahead to step 2:
When dividing 15 by 938, we get 0 with a remainder of 15.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 15 leaves us with 15.
Grab the next digit (5) from the dividend, add it to 15, then carry on: 155 / 938

On to step 3:
938 goes into 155 0 times with a remainder of 155.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 155 to get 155.
Include the next digit (9) from the dividend after 155, then repeat: 1559 / 938

Step 4:
1559 divided by 938 is 1 with a remainder of 621.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 938 away from 1559, we end up with 621.
Bring next digit (3) of the dividend behind the 621 and repeat the process: 6213 / 938

Step 5:
938 can be fit into 6213 6 times, resulting in a remainder of 585.
Write down 6 as next digit of the result. 
Result so far: 16.0
Subtract 5628 from 6213 to get 585.
Include the next digit (1) from the dividend after 585, then repeat: 5851 / 938

Step 6:
5851 divided by 938 is 6 with a remainder of 223.
Put 6 as the next digit of the answer. 
Result so far: 166.0
Deduct 5628 from 5851 and we're left with 223.
Grab the next digit (4) from the dividend, add it to 223, then carry on: 2234 / 938

Moving on to step 7:
2234 divided by 938 is 2 with a remainder of 358.
Put 2 as the next digit of the answer. 
Result so far: 1662.0
The remainder is 358 after subtracting 1876 from 2234.
Include the next digit (2) from the dividend after 358, then repeat: 3582 / 938

Advancing to step 8:
The number 938 fits into 3582 3 times, leaving a remainder of 768.
The number 3 becomes the next digit in our result. 
Result so far: 16623.0
The remainder is 768 after subtracting 2814 from 3582.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7680, and continue the process.

On to step 9:
7680 divided by 938 is 8 with a remainder of 176.
Use 8 as the next digit of our solution. 
Result so far: 16623.8
If we subtract 7504 from 7680, we get 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

On to step 10:
When dividing 1760 by 938, we get 1 with a remainder of 822.
Record the quotient 1 as the next digit in the result. 
Result so far: 16623.81
The remainder is 822 after subtracting 938 from 1760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8220, and continue the process.

Going ahead to step 11:
If we divide 8220 by 938, we get 8 and a remainder of 716.
Use 8 as the next digit of our solution. 
Result so far: 16623.818
Subtracting 7504 from 8220 leaves us with 716.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7160, and continue the process.

On to step 12:
938 can be fit into 7160 7 times, resulting in a remainder of 594.
Write down 7 as next digit of the result. 
Result so far: 16623.8187
If we subtract 6566 from 7160, we get 594.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5940, and continue the process.

On to step 13:
5940 divided by 938 is 6 with a remainder of 312.
Write down 6 as next digit of the result. 
Result so far: 16623.81876
Deduct 5628 from 5940 and we're left with 312.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

Going ahead to step 14:
938 can be fit into 3120 3 times, resulting in a remainder of 306.
The number 3 becomes the next digit in our result. 
Result so far: 16623.818763
Deduct 2814 from 3120 and we're left with 306.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3060, and continue the process.

On to step 15:
If we divide 3060 by 938, we get 3 and a remainder of 246.
Write down 3 as next digit of the result. 
Result so far: 16623.8187633
Subtracting 2814 from 3060 leaves us with 246.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2460, and continue the process.

The final outcome is 16623.8187633, with a leftover of 2.46e-06.
