91098644 ÷ 607 
The aim is to understand the frequency of 607 in 91098644.

Moving on to step 1:
607 can be fit into 9 0 times, resulting in a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Grab the next digit (1) from the dividend, add it to 9, then carry on: 91 / 607

Going ahead to step 2:
The number 607 fits into 91 0 times, leaving a remainder of 91.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 91, we get 91.
Grab the next digit (0) from the dividend, add it to 91, then carry on: 910 / 607

Let's proceed to step 3:
If we divide 910 by 607, we get 1 and a remainder of 303.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 607 away from 910, we end up with 303.
Bring next digit (9) of the dividend behind the 303 and repeat the process: 3039 / 607

Let's proceed to step 4:
607 goes into 3039 5 times with a remainder of 4.
Put 5 as the next digit of the answer. 
Result so far: 15.0
Subtracting 3035 from 3039 leaves us with 4.
Bring next digit (8) of the dividend behind the 4 and repeat the process: 48 / 607

Step 5:
When dividing 48 by 607, we get 0 with a remainder of 48.
Put 0 as the next digit of the answer. 
Result so far: 150.0
If we take 0 away from 48, we end up with 48.
Fetch the next digit (6) from the dividend, attach it to 48 and continue: 486 / 607

Going ahead to step 6:
When dividing 486 by 607, we get 0 with a remainder of 486.
Put 0 as the next digit of the answer. 
Result so far: 1500.0
Deduct 0 from 486 and we're left with 486.
Bring next digit (4) of the dividend behind the 486 and repeat the process: 4864 / 607

Moving on to step 7:
When dividing 4864 by 607, we get 8 with a remainder of 8.
Record the quotient 8 as the next digit in the result. 
Result so far: 15008.0
The remainder is 8 after subtracting 4856 from 4864.
Grab the next digit (4) from the dividend, add it to 8, then carry on: 84 / 607

On to step 8:
607 can be fit into 84 0 times, resulting in a remainder of 84.
Put 0 as the next digit of the answer. 
Result so far: 150080.0
Subtract 0 from 84 to get 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Moving on to step 9:
607 can be fit into 840 1 times, resulting in a remainder of 233.
Write down 1 as next digit of the result. 
Result so far: 150080.1
If we take 607 away from 840, we end up with 233.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2330, and continue the process.

On to step 10:
When dividing 2330 by 607, we get 3 with a remainder of 509.
Put 3 as the next digit of the answer. 
Result so far: 150080.13
Deduct 1821 from 2330 and we're left with 509.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5090, and continue the process.

Going ahead to step 11:
When dividing 5090 by 607, we get 8 with a remainder of 234.
Put 8 as the next digit of the answer. 
Result so far: 150080.138
Subtracting 4856 from 5090 leaves us with 234.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2340, and continue the process.

Moving on to step 12:
The number 607 fits into 2340 3 times, leaving a remainder of 519.
Write down 3 as next digit of the result. 
Result so far: 150080.1383
If we take 1821 away from 2340, we end up with 519.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5190, and continue the process.

Going ahead to step 13:
The number 607 fits into 5190 8 times, leaving a remainder of 334.
Put 8 as the next digit of the answer. 
Result so far: 150080.13838
If we take 4856 away from 5190, we end up with 334.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3340, and continue the process.

Going ahead to step 14:
607 goes into 3340 5 times with a remainder of 305.
Use 5 as the next digit of our solution. 
Result so far: 150080.138385
Deduct 3035 from 3340 and we're left with 305.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3050, and continue the process.

Going ahead to step 15:
If we divide 3050 by 607, we get 5 and a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 150080.1383855
Subtracting 3035 from 3050 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

The final outcome is 150080.1383855, with a leftover of 1.5e-07.
