39838443 divided by 978 
The aim is to understand the frequency of 978 in 39838443.

Step 1:
The number 978 fits into 3 0 times, leaving a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 978

Step 2:
When dividing 39 by 978, we get 0 with a remainder of 39.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 39, we get 39.
Bring next digit (8) of the dividend behind the 39 and repeat the process: 398 / 978

Step 3:
978 goes into 398 0 times with a remainder of 398.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 398 to get 398.
Take the next digit (3) from the dividend and append it to 398, then repeat: 3983 / 978

Step 4:
If we divide 3983 by 978, we get 4 and a remainder of 71.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Subtracting 3912 from 3983 leaves us with 71.
Take the next digit (8) from the dividend and append it to 71, then repeat: 718 / 978

Let's proceed to step 5:
If we divide 718 by 978, we get 0 and a remainder of 718.
Put 0 as the next digit of the answer. 
Result so far: 40.0
Subtracting 0 from 718 leaves us with 718.
Grab the next digit (4) from the dividend, add it to 718, then carry on: 7184 / 978

On to step 6:
When dividing 7184 by 978, we get 7 with a remainder of 338.
The number 7 becomes the next digit in our result. 
Result so far: 407.0
The remainder is 338 after subtracting 6846 from 7184.
Append the next digit (4) from the dividend to 338 and continue with: 3384 / 978

Step 7:
When dividing 3384 by 978, we get 3 with a remainder of 450.
Write down 3 as next digit of the result. 
Result so far: 4073.0
The remainder is 450 after subtracting 2934 from 3384.
Take the next digit (3) from the dividend and append it to 450, then repeat: 4503 / 978

Going ahead to step 8:
4503 divided by 978 is 4 with a remainder of 591.
Put 4 as the next digit of the answer. 
Result so far: 40734.0
Subtracting 3912 from 4503 leaves us with 591.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5910, and continue the process.

On to step 9:
The number 978 fits into 5910 6 times, leaving a remainder of 42.
Record the quotient 6 as the next digit in the result. 
Result so far: 40734.6
Subtracting 5868 from 5910 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 10:
978 goes into 420 0 times with a remainder of 420.
Record the quotient 0 as the next digit in the result. 
Result so far: 40734.6
If we subtract 0 from 420, we get 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

Let's proceed to step 11:
978 goes into 4200 4 times with a remainder of 288.
Use 4 as the next digit of our solution. 
Result so far: 40734.604
Deduct 3912 from 4200 and we're left with 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

Going ahead to step 12:
978 can be fit into 2880 2 times, resulting in a remainder of 924.
The number 2 becomes the next digit in our result. 
Result so far: 40734.6042
Subtracting 1956 from 2880 leaves us with 924.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9240, and continue the process.

Moving on to step 13:
If we divide 9240 by 978, we get 9 and a remainder of 438.
Write down 9 as next digit of the result. 
Result so far: 40734.60429
If we take 8802 away from 9240, we end up with 438.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4380, and continue the process.

On to step 14:
If we divide 4380 by 978, we get 4 and a remainder of 468.
The next digit of our result is 4. 
Result so far: 40734.604294
The remainder is 468 after subtracting 3912 from 4380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4680, and continue the process.

Advancing to step 15:
4680 divided by 978 is 4 with a remainder of 768.
The next digit of our result is 4. 
Result so far: 40734.6042944
Deduct 3912 from 4680 and we're left with 768.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7680, and continue the process.

After the division, we end up with 40734.6042944 and a remainder of 7.68e-06.
