77469043 ÷ 172 
We want to divide 77469043 by 172.

Advancing to step 1:
172 goes into 7 0 times with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Include the next digit (7) from the dividend after 7, then repeat: 77 / 172

Moving on to step 2:
172 can be fit into 77 0 times, resulting in a remainder of 77.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 77 and we're left with 77.
Append the next digit (4) from the dividend to 77 and continue with: 774 / 172

Advancing to step 3:
172 goes into 774 4 times with a remainder of 86.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Subtract 688 from 774 to get 86.
Include the next digit (6) from the dividend after 86, then repeat: 866 / 172

Step 4:
When dividing 866 by 172, we get 5 with a remainder of 6.
The next digit of our result is 5. 
Result so far: 45.0
If we subtract 860 from 866, we get 6.
Take the next digit (9) from the dividend and append it to 6, then repeat: 69 / 172

Step 5:
The number 172 fits into 69 0 times, leaving a remainder of 69.
The number 0 becomes the next digit in our result. 
Result so far: 450.0
Deduct 0 from 69 and we're left with 69.
Take the next digit (0) from the dividend and append it to 69, then repeat: 690 / 172

Let's proceed to step 6:
If we divide 690 by 172, we get 4 and a remainder of 2.
Record the quotient 4 as the next digit in the result. 
Result so far: 4504.0
Subtracting 688 from 690 leaves us with 2.
Take the next digit (4) from the dividend and append it to 2, then repeat: 24 / 172

Moving on to step 7:
If we divide 24 by 172, we get 0 and a remainder of 24.
Record the quotient 0 as the next digit in the result. 
Result so far: 45040.0
Subtracting 0 from 24 leaves us with 24.
Bring next digit (3) of the dividend behind the 24 and repeat the process: 243 / 172

Step 8:
172 goes into 243 1 times with a remainder of 71.
The number 1 becomes the next digit in our result. 
Result so far: 450401.0
Deduct 172 from 243 and we're left with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Advancing to step 9:
When dividing 710 by 172, we get 4 with a remainder of 22.
Use 4 as the next digit of our solution. 
Result so far: 450401.4
Subtract 688 from 710 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 10:
172 can be fit into 220 1 times, resulting in a remainder of 48.
Put 1 as the next digit of the answer. 
Result so far: 450401.41
Subtract 172 from 220 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 11:
480 divided by 172 is 2 with a remainder of 136.
Record the quotient 2 as the next digit in the result. 
Result so far: 450401.412
If we subtract 344 from 480, we get 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Going ahead to step 12:
The number 172 fits into 1360 7 times, leaving a remainder of 156.
Record the quotient 7 as the next digit in the result. 
Result so far: 450401.4127
Deduct 1204 from 1360 and we're left with 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

Moving on to step 13:
172 can be fit into 1560 9 times, resulting in a remainder of 12.
Put 9 as the next digit of the answer. 
Result so far: 450401.41279
The remainder is 12 after subtracting 1548 from 1560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 14:
When dividing 120 by 172, we get 0 with a remainder of 120.
Use 0 as the next digit of our solution. 
Result so far: 450401.41279
If we subtract 0 from 120, we get 120.
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 15:
1200 divided by 172 is 6 with a remainder of 168.
The next digit of our result is 6. 
Result so far: 450401.4127906
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.

On to step 16:
1680 divided by 172 is 9 with a remainder of 132.
Record the quotient 9 as the next digit in the result. 
Result so far: 450401.41279069
Subtract 1548 from 1680 to get 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Our division results in 450401.41279069 with a remaining 1.32e-07.
