91005341 divided by 751 
The aim is to understand the frequency of 751 in 91005341.

Step 1:
The number 751 fits into 9 0 times, leaving a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Append the next digit (1) from the dividend to 9 and continue with: 91 / 751

On to step 2:
91 divided by 751 is 0 with a remainder of 91.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 91 to get 91.
Grab the next digit (0) from the dividend, add it to 91, then carry on: 910 / 751

Step 3:
751 can be fit into 910 1 times, resulting in a remainder of 159.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 751 from 910 to get 159.
Grab the next digit (0) from the dividend, add it to 159, then carry on: 1590 / 751

Let's proceed to step 4:
751 goes into 1590 2 times with a remainder of 88.
Write down 2 as next digit of the result. 
Result so far: 12.0
Subtract 1502 from 1590 to get 88.
Include the next digit (5) from the dividend after 88, then repeat: 885 / 751

Step 5:
751 goes into 885 1 times with a remainder of 134.
Put 1 as the next digit of the answer. 
Result so far: 121.0
The remainder is 134 after subtracting 751 from 885.
Fetch the next digit (3) from the dividend, attach it to 134 and continue: 1343 / 751

Moving on to step 6:
751 goes into 1343 1 times with a remainder of 592.
Use 1 as the next digit of our solution. 
Result so far: 1211.0
Subtract 751 from 1343 to get 592.
Include the next digit (4) from the dividend after 592, then repeat: 5924 / 751

Moving on to step 7:
The number 751 fits into 5924 7 times, leaving a remainder of 667.
The number 7 becomes the next digit in our result. 
Result so far: 12117.0
The remainder is 667 after subtracting 5257 from 5924.
Fetch the next digit (1) from the dividend, attach it to 667 and continue: 6671 / 751

Advancing to step 8:
751 can be fit into 6671 8 times, resulting in a remainder of 663.
Put 8 as the next digit of the answer. 
Result so far: 121178.0
Deduct 6008 from 6671 and we're left with 663.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6630, and continue the process.

Advancing to step 9:
751 can be fit into 6630 8 times, resulting in a remainder of 622.
Write down 8 as next digit of the result. 
Result so far: 121178.8
If we take 6008 away from 6630, we end up with 622.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6220, and continue the process.

Moving on to step 10:
The number 751 fits into 6220 8 times, leaving a remainder of 212.
Put 8 as the next digit of the answer. 
Result so far: 121178.88
If we take 6008 away from 6220, we end up with 212.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

The quotient of the division is 121178.88, and the remainder is 0.212.
