3103720 divided by 942 
The aim is to understand the frequency of 942 in 3103720.

On to step 1:
If we divide 3 by 942, we get 0 and a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Fetch the next digit (1) from the dividend, attach it to 3 and continue: 31 / 942

On to step 2:
31 divided by 942 is 0 with a remainder of 31.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 31, we end up with 31.
Bring next digit (0) of the dividend behind the 31 and repeat the process: 310 / 942

Moving on to step 3:
942 can be fit into 310 0 times, resulting in a remainder of 310.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 310, we get 310.
Append the next digit (3) from the dividend to 310 and continue with: 3103 / 942

Step 4:
942 can be fit into 3103 3 times, resulting in a remainder of 277.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Deduct 2826 from 3103 and we're left with 277.
Append the next digit (7) from the dividend to 277 and continue with: 2777 / 942

Step 5:
When dividing 2777 by 942, we get 2 with a remainder of 893.
Write down 2 as next digit of the result. 
Result so far: 32.0
The remainder is 893 after subtracting 1884 from 2777.
Bring next digit (2) of the dividend behind the 893 and repeat the process: 8932 / 942

Advancing to step 6:
The number 942 fits into 8932 9 times, leaving a remainder of 454.
Record the quotient 9 as the next digit in the result. 
Result so far: 329.0
Deduct 8478 from 8932 and we're left with 454.
Take the next digit (0) from the dividend and append it to 454, then repeat: 4540 / 942

Advancing to step 7:
942 can be fit into 4540 4 times, resulting in a remainder of 772.
Use 4 as the next digit of our solution. 
Result so far: 3294.0
Deduct 3768 from 4540 and we're left with 772.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7720, and continue the process.

Moving on to step 8:
The number 942 fits into 7720 8 times, leaving a remainder of 184.
Record the quotient 8 as the next digit in the result. 
Result so far: 3294.8
Deduct 7536 from 7720 and we're left with 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Let's proceed to step 9:
942 goes into 1840 1 times with a remainder of 898.
Write down 1 as next digit of the result. 
Result so far: 3294.81
Deduct 942 from 1840 and we're left with 898.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8980, and continue the process.

Going ahead to step 10:
942 can be fit into 8980 9 times, resulting in a remainder of 502.
The next digit of our result is 9. 
Result so far: 3294.819
If we take 8478 away from 8980, we end up with 502.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5020, and continue the process.

Step 11:
942 can be fit into 5020 5 times, resulting in a remainder of 310.
Use 5 as the next digit of our solution. 
Result so far: 3294.8195
The remainder is 310 after subtracting 4710 from 5020.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Let's proceed to step 12:
If we divide 3100 by 942, we get 3 and a remainder of 274.
Record the quotient 3 as the next digit in the result. 
Result so far: 3294.81953
Subtracting 2826 from 3100 leaves us with 274.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2740, and continue the process.

On to step 13:
942 goes into 2740 2 times with a remainder of 856.
The next digit of our result is 2. 
Result so far: 3294.819532
If we take 1884 away from 2740, we end up with 856.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8560, and continue the process.

Advancing to step 14:
942 can be fit into 8560 9 times, resulting in a remainder of 82.
Use 9 as the next digit of our solution. 
Result so far: 3294.8195329
Subtract 8478 from 8560 to get 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

On to step 15:
820 divided by 942 is 0 with a remainder of 820.
Write down 0 as next digit of the result. 
Result so far: 3294.8195329
Deduct 0 from 820 and we're left with 820.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8200, and continue the process.

After the division, we end up with 3294.8195329 and a remainder of 8.2e-07.
