3757638 divided by 968 
The aim is to understand the frequency of 968 in 3757638.

Going ahead to step 1:
3 divided by 968 is 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Append the next digit (7) from the dividend to 3 and continue with: 37 / 968

Let's proceed to step 2:
968 can be fit into 37 0 times, resulting in a remainder of 37.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 37 after subtracting 0 from 37.
Grab the next digit (5) from the dividend, add it to 37, then carry on: 375 / 968

Moving on to step 3:
The number 968 fits into 375 0 times, leaving a remainder of 375.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 375 after subtracting 0 from 375.
Fetch the next digit (7) from the dividend, attach it to 375 and continue: 3757 / 968

Step 4:
968 goes into 3757 3 times with a remainder of 853.
Use 3 as the next digit of our solution. 
Result so far: 3.0
The remainder is 853 after subtracting 2904 from 3757.
Grab the next digit (6) from the dividend, add it to 853, then carry on: 8536 / 968

Let's proceed to step 5:
8536 divided by 968 is 8 with a remainder of 792.
Put 8 as the next digit of the answer. 
Result so far: 38.0
If we subtract 7744 from 8536, we get 792.
Grab the next digit (3) from the dividend, add it to 792, then carry on: 7923 / 968

Let's proceed to step 6:
968 can be fit into 7923 8 times, resulting in a remainder of 179.
Use 8 as the next digit of our solution. 
Result so far: 388.0
If we take 7744 away from 7923, we end up with 179.
Grab the next digit (8) from the dividend, add it to 179, then carry on: 1798 / 968

Advancing to step 7:
968 can be fit into 1798 1 times, resulting in a remainder of 830.
Use 1 as the next digit of our solution. 
Result so far: 3881.0
The remainder is 830 after subtracting 968 from 1798.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8300, and continue the process.

Moving on to step 8:
When dividing 8300 by 968, we get 8 with a remainder of 556.
Write down 8 as next digit of the result. 
Result so far: 3881.8
If we subtract 7744 from 8300, we get 556.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5560, and continue the process.

Going ahead to step 9:
5560 divided by 968 is 5 with a remainder of 720.
Put 5 as the next digit of the answer. 
Result so far: 3881.85
The remainder is 720 after subtracting 4840 from 5560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7200, and continue the process.

Advancing to step 10:
When dividing 7200 by 968, we get 7 with a remainder of 424.
Put 7 as the next digit of the answer. 
Result so far: 3881.857
Deduct 6776 from 7200 and we're left with 424.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4240, and continue the process.

Let's proceed to step 11:
The number 968 fits into 4240 4 times, leaving a remainder of 368.
The next digit of our result is 4. 
Result so far: 3881.8574
Subtracting 3872 from 4240 leaves us with 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

Step 12:
If we divide 3680 by 968, we get 3 and a remainder of 776.
Put 3 as the next digit of the answer. 
Result so far: 3881.85743
If we take 2904 away from 3680, we end up with 776.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7760, and continue the process.

Advancing to step 13:
The number 968 fits into 7760 8 times, leaving a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 3881.857438
Deduct 7744 from 7760 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 14:
The number 968 fits into 160 0 times, leaving a remainder of 160.
Put 0 as the next digit of the answer. 
Result so far: 3881.857438
If we take 0 away from 160, we end up with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Going ahead to step 15:
If we divide 1600 by 968, we get 1 and a remainder of 632.
The next digit of our result is 1. 
Result so far: 3881.85743801
Subtracting 968 from 1600 leaves us with 632.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6320, and continue the process.

The final outcome is 3881.85743801, with a leftover of 6.32e-07.
