We divide 77166171 by 145
We want to figure out the number of times 77166171 can be divided by 145.

Step 1:
145 can be fit into 7 0 times, resulting in a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Grab the next digit (7) from the dividend, add it to 7, then carry on: 77 / 145

Advancing to step 2:
145 goes into 77 0 times with a remainder of 77.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 77, we get 77.
Append the next digit (1) from the dividend to 77 and continue with: 771 / 145

Advancing to step 3:
771 divided by 145 is 5 with a remainder of 46.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
The remainder is 46 after subtracting 725 from 771.
Include the next digit (6) from the dividend after 46, then repeat: 466 / 145

On to step 4:
When dividing 466 by 145, we get 3 with a remainder of 31.
The number 3 becomes the next digit in our result. 
Result so far: 53.0
The remainder is 31 after subtracting 435 from 466.
Fetch the next digit (6) from the dividend, attach it to 31 and continue: 316 / 145

Moving on to step 5:
When dividing 316 by 145, we get 2 with a remainder of 26.
Record the quotient 2 as the next digit in the result. 
Result so far: 532.0
Deduct 290 from 316 and we're left with 26.
Grab the next digit (1) from the dividend, add it to 26, then carry on: 261 / 145

Let's proceed to step 6:
If we divide 261 by 145, we get 1 and a remainder of 116.
Use 1 as the next digit of our solution. 
Result so far: 5321.0
Deduct 145 from 261 and we're left with 116.
Grab the next digit (7) from the dividend, add it to 116, then carry on: 1167 / 145

Moving on to step 7:
The number 145 fits into 1167 8 times, leaving a remainder of 7.
Put 8 as the next digit of the answer. 
Result so far: 53218.0
Subtracting 1160 from 1167 leaves us with 7.
Include the next digit (1) from the dividend after 7, then repeat: 71 / 145

Going ahead to step 8:
145 can be fit into 71 0 times, resulting in a remainder of 71.
Use 0 as the next digit of our solution. 
Result so far: 532180.0
If we take 0 away from 71, we end up 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.

Let's proceed to step 9:
710 divided by 145 is 4 with a remainder of 130.
Write down 4 as next digit of the result. 
Result so far: 532180.4
If we subtract 580 from 710, we get 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Let's proceed to step 10:
If we divide 1300 by 145, we get 8 and a remainder of 140.
Record the quotient 8 as the next digit in the result. 
Result so far: 532180.48
Subtract 1160 from 1300 to get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Advancing to step 11:
145 goes into 1400 9 times with a remainder of 95.
Record the quotient 9 as the next digit in the result. 
Result so far: 532180.489
Subtract 1305 from 1400 to get 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

Step 12:
145 can be fit into 950 6 times, resulting in a remainder of 80.
Record the quotient 6 as the next digit in the result. 
Result so far: 532180.4896
Subtract 870 from 950 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

On to step 13:
The number 145 fits into 800 5 times, leaving a remainder of 75.
Use 5 as the next digit of our solution. 
Result so far: 532180.48965
If we subtract 725 from 800, we get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Step 14:
The number 145 fits into 750 5 times, leaving a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 532180.489655
Subtract 725 from 750 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

The final outcome is 532180.489655, with a leftover of 2.5e-06.
