74489191 ÷ 921 
Our goal is to divide 74489191 by 921.

Let's proceed to step 1:
The number 921 fits into 7 0 times, leaving a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Bring next digit (4) of the dividend behind the 7 and repeat the process: 74 / 921

Going ahead to step 2:
921 goes into 74 0 times with a remainder of 74.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 74 leaves us with 74.
Take the next digit (4) from the dividend and append it to 74, then repeat: 744 / 921

Going ahead to step 3:
921 can be fit into 744 0 times, resulting in a remainder of 744.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 744, we get 744.
Bring next digit (8) of the dividend behind the 744 and repeat the process: 7448 / 921

Let's proceed to step 4:
If we divide 7448 by 921, we get 8 and a remainder of 80.
Write down 8 as next digit of the result. 
Result so far: 8.0
Subtract 7368 from 7448 to get 80.
Grab the next digit (9) from the dividend, add it to 80, then carry on: 809 / 921

Moving on to step 5:
The number 921 fits into 809 0 times, leaving a remainder of 809.
The number 0 becomes the next digit in our result. 
Result so far: 80.0
Subtracting 0 from 809 leaves us with 809.
Take the next digit (1) from the dividend and append it to 809, then repeat: 8091 / 921

Going ahead to step 6:
When dividing 8091 by 921, we get 8 with a remainder of 723.
Record the quotient 8 as the next digit in the result. 
Result so far: 808.0
Subtracting 7368 from 8091 leaves us with 723.
Grab the next digit (9) from the dividend, add it to 723, then carry on: 7239 / 921

Going ahead to step 7:
921 can be fit into 7239 7 times, resulting in a remainder of 792.
Record the quotient 7 as the next digit in the result. 
Result so far: 8087.0
If we take 6447 away from 7239, we end up with 792.
Fetch the next digit (1) from the dividend, attach it to 792 and continue: 7921 / 921

Going ahead to step 8:
921 can be fit into 7921 8 times, resulting in a remainder of 553.
Record the quotient 8 as the next digit in the result. 
Result so far: 80878.0
If we subtract 7368 from 7921, we get 553.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5530, and continue the process.

Step 9:
If we divide 5530 by 921, we get 6 and a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 80878.6
If we subtract 5526 from 5530, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 10:
921 goes into 40 0 times with a remainder of 40.
The next digit of our result is 0. 
Result so far: 80878.6
Subtract 0 from 40 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 11:
400 divided by 921 is 0 with a remainder of 400.
Write down 0 as next digit of the result. 
Result so far: 80878.6
Subtracting 0 from 400 leaves us with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

After the division, we end up with 80878.6 and a remainder of 0.04.
