74978879 ÷ 531 
We want to figure out the number of times 74978879 can be divided by 531.

Moving on to step 1:
531 goes into 7 0 times with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Grab the next digit (4) from the dividend, add it to 7, then carry on: 74 / 531

Advancing to step 2:
531 can be fit into 74 0 times, resulting in a remainder of 74.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 74, we get 74.
Fetch the next digit (9) from the dividend, attach it to 74 and continue: 749 / 531

Going ahead to step 3:
If we divide 749 by 531, we get 1 and a remainder of 218.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 531 away from 749, we end up with 218.
Append the next digit (7) from the dividend to 218 and continue with: 2187 / 531

Let's proceed to step 4:
2187 divided by 531 is 4 with a remainder of 63.
The next digit of our result is 4. 
Result so far: 14.0
If we take 2124 away from 2187, we end up with 63.
Grab the next digit (8) from the dividend, add it to 63, then carry on: 638 / 531

Let's proceed to step 5:
If we divide 638 by 531, we get 1 and a remainder of 107.
The next digit of our result is 1. 
Result so far: 141.0
If we subtract 531 from 638, we get 107.
Grab the next digit (8) from the dividend, add it to 107, then carry on: 1078 / 531

Going ahead to step 6:
531 goes into 1078 2 times with a remainder of 16.
Use 2 as the next digit of our solution. 
Result so far: 1412.0
Subtract 1062 from 1078 to get 16.
Grab the next digit (7) from the dividend, add it to 16, then carry on: 167 / 531

Let's proceed to step 7:
When dividing 167 by 531, we get 0 with a remainder of 167.
Record the quotient 0 as the next digit in the result. 
Result so far: 14120.0
Subtracting 0 from 167 leaves us with 167.
Bring next digit (9) of the dividend behind the 167 and repeat the process: 1679 / 531

Advancing to step 8:
If we divide 1679 by 531, we get 3 and a remainder of 86.
Use 3 as the next digit of our solution. 
Result so far: 141203.0
Subtract 1593 from 1679 to get 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Advancing to step 9:
The number 531 fits into 860 1 times, leaving a remainder of 329.
Write down 1 as next digit of the result. 
Result so far: 141203.1
The remainder is 329 after subtracting 531 from 860.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3290, and continue the process.

Moving on to step 10:
3290 divided by 531 is 6 with a remainder of 104.
Use 6 as the next digit of our solution. 
Result so far: 141203.16
Subtracting 3186 from 3290 leaves us with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Let's proceed to step 11:
When dividing 1040 by 531, we get 1 with a remainder of 509.
The next digit of our result is 1. 
Result so far: 141203.161
If we subtract 531 from 1040, we get 509.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5090, and continue the process.

On to step 12:
If we divide 5090 by 531, we get 9 and a remainder of 311.
The number 9 becomes the next digit in our result. 
Result so far: 141203.1619
Subtracting 4779 from 5090 leaves us with 311.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3110, and continue the process.

Advancing to step 13:
3110 divided by 531 is 5 with a remainder of 455.
Record the quotient 5 as the next digit in the result. 
Result so far: 141203.16195
If we subtract 2655 from 3110, we get 455.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4550, and continue the process.

On to step 14:
If we divide 4550 by 531, we get 8 and a remainder of 302.
Use 8 as the next digit of our solution. 
Result so far: 141203.161958
If we take 4248 away from 4550, we end up with 302.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3020, and continue the process.

Let's proceed to step 15:
531 goes into 3020 5 times with a remainder of 365.
Record the quotient 5 as the next digit in the result. 
Result so far: 141203.1619585
Deduct 2655 from 3020 and we're left with 365.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3650, and continue the process.

Step 16:
When dividing 3650 by 531, we get 6 with a remainder of 464.
Use 6 as the next digit of our solution. 
Result so far: 141203.16195856
Subtracting 3186 from 3650 leaves us with 464.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4640, and continue the process.

The quotient of the division is 141203.16195856, and the remainder is 4.64e-07.
