We divide 3948361 by 616
The aim is to understand the frequency of 616 in 3948361.

On to step 1:
When dividing 3 by 616, we get 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 616

On to step 2:
When dividing 39 by 616, we get 0 with a remainder of 39.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 39 and we're left with 39.
Fetch the next digit (4) from the dividend, attach it to 39 and continue: 394 / 616

Step 3:
When dividing 394 by 616, we get 0 with a remainder of 394.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 394, we get 394.
Fetch the next digit (8) from the dividend, attach it to 394 and continue: 3948 / 616

Advancing to step 4:
3948 divided by 616 is 6 with a remainder of 252.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
Subtract 3696 from 3948 to get 252.
Bring next digit (3) of the dividend behind the 252 and repeat the process: 2523 / 616

Going ahead to step 5:
If we divide 2523 by 616, we get 4 and a remainder of 59.
Use 4 as the next digit of our solution. 
Result so far: 64.0
If we subtract 2464 from 2523, we get 59.
Take the next digit (6) from the dividend and append it to 59, then repeat: 596 / 616

Let's proceed to step 6:
616 goes into 596 0 times with a remainder of 596.
The number 0 becomes the next digit in our result. 
Result so far: 640.0
Deduct 0 from 596 and we're left with 596.
Fetch the next digit (1) from the dividend, attach it to 596 and continue: 5961 / 616

On to step 7:
The number 616 fits into 5961 9 times, leaving a remainder of 417.
Put 9 as the next digit of the answer. 
Result so far: 6409.0
Subtract 5544 from 5961 to get 417.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4170, and continue the process.

Step 8:
The number 616 fits into 4170 6 times, leaving a remainder of 474.
Write down 6 as next digit of the result. 
Result so far: 6409.6
The remainder is 474 after subtracting 3696 from 4170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4740, and continue the process.

Going ahead to step 9:
The number 616 fits into 4740 7 times, leaving a remainder of 428.
Write down 7 as next digit of the result. 
Result so far: 6409.67
Deduct 4312 from 4740 and we're left with 428.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4280, and continue the process.

Let's proceed to step 10:
If we divide 4280 by 616, we get 6 and a remainder of 584.
Write down 6 as next digit of the result. 
Result so far: 6409.676
Subtracting 3696 from 4280 leaves us with 584.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5840, and continue the process.

On to step 11:
5840 divided by 616 is 9 with a remainder of 296.
Use 9 as the next digit of our solution. 
Result so far: 6409.6769
If we subtract 5544 from 5840, we get 296.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

Moving on to step 12:
If we divide 2960 by 616, we get 4 and a remainder of 496.
Record the quotient 4 as the next digit in the result. 
Result so far: 6409.67694
Deduct 2464 from 2960 and we're left with 496.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4960, and continue the process.

Let's proceed to step 13:
616 can be fit into 4960 8 times, resulting in a remainder of 32.
The number 8 becomes the next digit in our result. 
Result so far: 6409.676948
The remainder is 32 after subtracting 4928 from 4960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 14:
616 goes into 320 0 times with a remainder of 320.
The number 0 becomes the next digit in our result. 
Result so far: 6409.676948
If we take 0 away from 320, we end up with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Moving on to step 15:
If we divide 3200 by 616, we get 5 and a remainder of 120.
Use 5 as the next digit of our solution. 
Result so far: 6409.67694805
Subtracting 3080 from 3200 leaves us with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

In conclusion, the division gives 6409.67694805 with a balance of 1.2e-07.
