74310140 divided by 172 
We want to figure out the number of times 74310140 can be divided by 172.

Going ahead to step 1:
When dividing 7 by 172, we get 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Grab the next digit (4) from the dividend, add it to 7, then carry on: 74 / 172

Moving on to step 2:
The number 172 fits into 74 0 times, leaving a remainder of 74.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 74 leaves us with 74.
Bring next digit (3) of the dividend behind the 74 and repeat the process: 743 / 172

Let's proceed to step 3:
When dividing 743 by 172, we get 4 with a remainder of 55.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
The remainder is 55 after subtracting 688 from 743.
Append the next digit (1) from the dividend to 55 and continue with: 551 / 172

Step 4:
If we divide 551 by 172, we get 3 and a remainder of 35.
Record the quotient 3 as the next digit in the result. 
Result so far: 43.0
Subtracting 516 from 551 leaves us with 35.
Include the next digit (0) from the dividend after 35, then repeat: 350 / 172

Going ahead to step 5:
350 divided by 172 is 2 with a remainder of 6.
Use 2 as the next digit of our solution. 
Result so far: 432.0
Deduct 344 from 350 and we're left with 6.
Take the next digit (1) from the dividend and append it to 6, then repeat: 61 / 172

Going ahead to step 6:
When dividing 61 by 172, we get 0 with a remainder of 61.
Use 0 as the next digit of our solution. 
Result so far: 4320.0
The remainder is 61 after subtracting 0 from 61.
Append the next digit (4) from the dividend to 61 and continue with: 614 / 172

Advancing to step 7:
The number 172 fits into 614 3 times, leaving a remainder of 98.
Write down 3 as next digit of the result. 
Result so far: 43203.0
The remainder is 98 after subtracting 516 from 614.
Include the next digit (0) from the dividend after 98, then repeat: 980 / 172

Let's proceed to step 8:
The number 172 fits into 980 5 times, leaving a remainder of 120.
Put 5 as the next digit of the answer. 
Result so far: 432035.0
The remainder is 120 after subtracting 860 from 980.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Moving on to step 9:
172 can be fit into 1200 6 times, resulting in a remainder of 168.
Use 6 as the next digit of our solution. 
Result so far: 432035.6
Subtract 1032 from 1200 to get 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

Going ahead to step 10:
1680 divided by 172 is 9 with a remainder of 132.
Use 9 as the next digit of our solution. 
Result so far: 432035.69
The remainder is 132 after subtracting 1548 from 1680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Going ahead to step 11:
172 goes into 1320 7 times with a remainder of 116.
The number 7 becomes the next digit in our result. 
Result so far: 432035.697
The remainder is 116 after subtracting 1204 from 1320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Let's proceed to step 12:
172 can be fit into 1160 6 times, resulting in a remainder of 128.
Use 6 as the next digit of our solution. 
Result so far: 432035.6976
Deduct 1032 from 1160 and we're left with 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Advancing to step 13:
The number 172 fits into 1280 7 times, leaving a remainder of 76.
Record the quotient 7 as the next digit in the result. 
Result so far: 432035.69767
If we take 1204 away from 1280, we end up with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Going ahead to step 14:
172 goes into 760 4 times with a remainder of 72.
Write down 4 as next digit of the result. 
Result so far: 432035.697674
The remainder is 72 after subtracting 688 from 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Step 15:
The number 172 fits into 720 4 times, leaving a remainder of 32.
Put 4 as the next digit of the answer. 
Result so far: 432035.6976744
Deduct 688 from 720 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

The quotient of the division is 432035.6976744, and the remainder is 3.2e-07.
