We're dividing 7543561 by 749 
We want to divide 7543561 by 749.

Going ahead to step 1:
749 can be fit into 7 0 times, resulting in a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Fetch the next digit (5) from the dividend, attach it to 7 and continue: 75 / 749

Let's proceed to step 2:
749 can be fit into 75 0 times, resulting in a remainder of 75.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 75, we get 75.
Fetch the next digit (4) from the dividend, attach it to 75 and continue: 754 / 749

Advancing to step 3:
749 goes into 754 1 times with a remainder of 5.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 5 after subtracting 749 from 754.
Take the next digit (3) from the dividend and append it to 5, then repeat: 53 / 749

Going ahead to step 4:
749 can be fit into 53 0 times, resulting in a remainder of 53.
Use 0 as the next digit of our solution. 
Result so far: 10.0
Subtracting 0 from 53 leaves us with 53.
Grab the next digit (5) from the dividend, add it to 53, then carry on: 535 / 749

Going ahead to step 5:
749 goes into 535 0 times with a remainder of 535.
The next digit of our result is 0. 
Result so far: 100.0
If we take 0 away from 535, we end up with 535.
Append the next digit (6) from the dividend to 535 and continue with: 5356 / 749

Step 6:
When dividing 5356 by 749, we get 7 with a remainder of 113.
Put 7 as the next digit of the answer. 
Result so far: 1007.0
Subtract 5243 from 5356 to get 113.
Take the next digit (1) from the dividend and append it to 113, then repeat: 1131 / 749

Advancing to step 7:
The number 749 fits into 1131 1 times, leaving a remainder of 382.
The number 1 becomes the next digit in our result. 
Result so far: 10071.0
Deduct 749 from 1131 and we're left with 382.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3820, and continue the process.

On to step 8:
749 can be fit into 3820 5 times, resulting in a remainder of 75.
The number 5 becomes the next digit in our result. 
Result so far: 10071.5
The remainder is 75 after subtracting 3745 from 3820.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Going ahead to step 9:
749 goes into 750 1 times with a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 10071.51
Deduct 749 from 750 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 10:
749 goes into 10 0 times with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 10071.51
If we take 0 away from 10, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 11:
When dividing 100 by 749, we get 0 with a remainder of 100.
Write down 0 as next digit of the result. 
Result so far: 10071.51
If we take 0 away from 100, we end up with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

After the division, we end up with 10071.51 and a remainder of 0.001.
