We're dividing 19713679 by 945 
The aim is to understand the frequency of 945 in 19713679.

On to step 1:
945 can be fit into 1 0 times, resulting in a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Grab the next digit (9) from the dividend, add it to 1, then carry on: 19 / 945

Moving on to step 2:
19 divided by 945 is 0 with a remainder of 19.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 19, we end up with 19.
Grab the next digit (7) from the dividend, add it to 19, then carry on: 197 / 945

Advancing to step 3:
945 goes into 197 0 times with a remainder of 197.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 197, we get 197.
Bring next digit (1) of the dividend behind the 197 and repeat the process: 1971 / 945

Step 4:
1971 divided by 945 is 2 with a remainder of 81.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we take 1890 away from 1971, we end up with 81.
Bring next digit (3) of the dividend behind the 81 and repeat the process: 813 / 945

Let's proceed to step 5:
If we divide 813 by 945, we get 0 and a remainder of 813.
The number 0 becomes the next digit in our result. 
Result so far: 20.0
The remainder is 813 after subtracting 0 from 813.
Fetch the next digit (6) from the dividend, attach it to 813 and continue: 8136 / 945

Going ahead to step 6:
If we divide 8136 by 945, we get 8 and a remainder of 576.
Record the quotient 8 as the next digit in the result. 
Result so far: 208.0
Subtract 7560 from 8136 to get 576.
Append the next digit (7) from the dividend to 576 and continue with: 5767 / 945

On to step 7:
5767 divided by 945 is 6 with a remainder of 97.
Write down 6 as next digit of the result. 
Result so far: 2086.0
Subtract 5670 from 5767 to get 97.
Append the next digit (9) from the dividend to 97 and continue with: 979 / 945

Moving on to step 8:
If we divide 979 by 945, we get 1 and a remainder of 34.
Write down 1 as next digit of the result. 
Result so far: 20861.0
Deduct 945 from 979 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Going ahead to step 9:
If we divide 340 by 945, we get 0 and a remainder of 340.
The number 0 becomes the next digit in our result. 
Result so far: 20861.0
If we subtract 0 from 340, we get 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Advancing to step 10:
945 can be fit into 3400 3 times, resulting in a remainder of 565.
Write down 3 as next digit of the result. 
Result so far: 20861.03
If we take 2835 away from 3400, we end up with 565.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5650, and continue the process.

Moving on to step 11:
5650 divided by 945 is 5 with a remainder of 925.
Write down 5 as next digit of the result. 
Result so far: 20861.035
If we subtract 4725 from 5650, we get 925.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9250, and continue the process.

Going ahead to step 12:
945 goes into 9250 9 times with a remainder of 745.
Write down 9 as next digit of the result. 
Result so far: 20861.0359
Subtract 8505 from 9250 to get 745.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7450, and continue the process.

Advancing to step 13:
When dividing 7450 by 945, we get 7 with a remainder of 835.
Write down 7 as next digit of the result. 
Result so far: 20861.03597
The remainder is 835 after subtracting 6615 from 7450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8350, and continue the process.

Going ahead to step 14:
If we divide 8350 by 945, we get 8 and a remainder of 790.
Put 8 as the next digit of the answer. 
Result so far: 20861.035978
Subtracting 7560 from 8350 leaves us with 790.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7900, and continue the process.

On to step 15:
The number 945 fits into 7900 8 times, leaving a remainder of 340.
Write down 8 as next digit of the result. 
Result so far: 20861.0359788
Deduct 7560 from 7900 and we're left with 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Our division results in 20861.0359788 with a remaining 3.4e-06.
