We're dividing 73748994 by 607 
The aim is to understand the frequency of 607 in 73748994.

On to step 1:
When dividing 7 by 607, we get 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Append the next digit (3) from the dividend to 7 and continue with: 73 / 607

On to step 2:
73 divided by 607 is 0 with a remainder of 73.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 73, we get 73.
Include the next digit (7) from the dividend after 73, then repeat: 737 / 607

On to step 3:
When dividing 737 by 607, we get 1 with a remainder of 130.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 607 from 737 and we're left with 130.
Grab the next digit (4) from the dividend, add it to 130, then carry on: 1304 / 607

Let's proceed to step 4:
When dividing 1304 by 607, we get 2 with a remainder of 90.
The next digit of our result is 2. 
Result so far: 12.0
Subtract 1214 from 1304 to get 90.
Bring next digit (8) of the dividend behind the 90 and repeat the process: 908 / 607

On to step 5:
When dividing 908 by 607, we get 1 with a remainder of 301.
Write down 1 as next digit of the result. 
Result so far: 121.0
If we take 607 away from 908, we end up with 301.
Fetch the next digit (9) from the dividend, attach it to 301 and continue: 3019 / 607

Let's proceed to step 6:
607 goes into 3019 4 times with a remainder of 591.
Put 4 as the next digit of the answer. 
Result so far: 1214.0
Subtracting 2428 from 3019 leaves us with 591.
Take the next digit (9) from the dividend and append it to 591, then repeat: 5919 / 607

Step 7:
607 can be fit into 5919 9 times, resulting in a remainder of 456.
The next digit of our result is 9. 
Result so far: 12149.0
Deduct 5463 from 5919 and we're left with 456.
Append the next digit (4) from the dividend to 456 and continue with: 4564 / 607

Let's proceed to step 8:
If we divide 4564 by 607, we get 7 and a remainder of 315.
Write down 7 as next digit of the result. 
Result so far: 121497.0
The remainder is 315 after subtracting 4249 from 4564.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3150, and continue the process.

Let's proceed to step 9:
607 can be fit into 3150 5 times, resulting in a remainder of 115.
Write down 5 as next digit of the result. 
Result so far: 121497.5
If we take 3035 away from 3150, we end up with 115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

Let's proceed to step 10:
607 goes into 1150 1 times with a remainder of 543.
The next digit of our result is 1. 
Result so far: 121497.51
If we take 607 away from 1150, we end up with 543.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5430, and continue the process.

Advancing to step 11:
If we divide 5430 by 607, we get 8 and a remainder of 574.
Put 8 as the next digit of the answer. 
Result so far: 121497.518
If we take 4856 away from 5430, we end up with 574.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5740, and continue the process.

On to step 12:
607 goes into 5740 9 times with a remainder of 277.
Put 9 as the next digit of the answer. 
Result so far: 121497.5189
Deduct 5463 from 5740 and we're left with 277.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2770, and continue the process.

Advancing to step 13:
The number 607 fits into 2770 4 times, leaving a remainder of 342.
The next digit of our result is 4. 
Result so far: 121497.51894
If we subtract 2428 from 2770, we get 342.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3420, and continue the process.

Advancing to step 14:
3420 divided by 607 is 5 with a remainder of 385.
Record the quotient 5 as the next digit in the result. 
Result so far: 121497.518945
If we subtract 3035 from 3420, we get 385.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3850, and continue the process.

Let's proceed to step 15:
The number 607 fits into 3850 6 times, leaving a remainder of 208.
Write down 6 as next digit of the result. 
Result so far: 121497.5189456
If we take 3642 away from 3850, we end up with 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Let's proceed to step 16:
607 can be fit into 2080 3 times, resulting in a remainder of 259.
Put 3 as the next digit of the answer. 
Result so far: 121497.51894563
The remainder is 259 after subtracting 1821 from 2080.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2590, and continue the process.

After the division, we end up with 121497.51894563 and a remainder of 2.59e-07.
