We're dividing 74379783 by 197 
The aim is to understand the frequency of 197 in 74379783.

On to step 1:
7 divided by 197 is 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Grab the next digit (4) from the dividend, add it to 7, then carry on: 74 / 197

Advancing to step 2:
The number 197 fits into 74 0 times, leaving a remainder of 74.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 74 leaves us with 74.
Fetch the next digit (3) from the dividend, attach it to 74 and continue: 743 / 197

Advancing to step 3:
When dividing 743 by 197, we get 3 with a remainder of 152.
Put 3 as the next digit of the answer. 
Result so far: 3.0
The remainder is 152 after subtracting 591 from 743.
Take the next digit (7) from the dividend and append it to 152, then repeat: 1527 / 197

Going ahead to step 4:
When dividing 1527 by 197, we get 7 with a remainder of 148.
Record the quotient 7 as the next digit in the result. 
Result so far: 37.0
If we subtract 1379 from 1527, we get 148.
Take the next digit (9) from the dividend and append it to 148, then repeat: 1489 / 197

On to step 5:
1489 divided by 197 is 7 with a remainder of 110.
Use 7 as the next digit of our solution. 
Result so far: 377.0
The remainder is 110 after subtracting 1379 from 1489.
Append the next digit (7) from the dividend to 110 and continue with: 1107 / 197

Going ahead to step 6:
1107 divided by 197 is 5 with a remainder of 122.
The next digit of our result is 5. 
Result so far: 3775.0
Subtract 985 from 1107 to get 122.
Grab the next digit (8) from the dividend, add it to 122, then carry on: 1228 / 197

Advancing to step 7:
The number 197 fits into 1228 6 times, leaving a remainder of 46.
Use 6 as the next digit of our solution. 
Result so far: 37756.0
Subtract 1182 from 1228 to get 46.
Take the next digit (3) from the dividend and append it to 46, then repeat: 463 / 197

On to step 8:
197 can be fit into 463 2 times, resulting in a remainder of 69.
Put 2 as the next digit of the answer. 
Result so far: 377562.0
If we take 394 away from 463, we end up with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Advancing to step 9:
The number 197 fits into 690 3 times, leaving a remainder of 99.
The next digit of our result is 3. 
Result so far: 377562.3
If we subtract 591 from 690, we get 99.
Since there are no more digits in the dividend, we add a zero to the remainder making it 990, and continue the process.

Advancing to step 10:
197 goes into 990 5 times with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 377562.35
The remainder is 5 after subtracting 985 from 990.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 11:
If we divide 50 by 197, we get 0 and a remainder of 50.
Write down 0 as next digit of the result. 
Result so far: 377562.35
Deduct 0 from 50 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 12:
When dividing 500 by 197, we get 2 with a remainder of 106.
Record the quotient 2 as the next digit in the result. 
Result so far: 377562.3502
If we subtract 394 from 500, we get 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Going ahead to step 13:
The number 197 fits into 1060 5 times, leaving a remainder of 75.
Write down 5 as next digit of the result. 
Result so far: 377562.35025
If we take 985 away from 1060, we end up with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

On to step 14:
197 goes into 750 3 times with a remainder of 159.
Use 3 as the next digit of our solution. 
Result so far: 377562.350253
The remainder is 159 after subtracting 591 from 750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1590, and continue the process.

On to step 15:
When dividing 1590 by 197, we get 8 with a remainder of 14.
The number 8 becomes the next digit in our result. 
Result so far: 377562.3502538
Subtract 1576 from 1590 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 16:
197 goes into 140 0 times with a remainder of 140.
Put 0 as the next digit of the answer. 
Result so far: 377562.3502538
Deduct 0 from 140 and we're left with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

The final result is 377562.3502538 with a remainder of 1.4e-07.
