We're dividing 78734165 by 170 
Our goal is to divide 78734165 by 170.

Let's proceed to step 1:
7 divided by 170 is 0 with 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.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 170

Advancing to step 2:
The number 170 fits into 78 0 times, leaving a remainder of 78.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 78, we end up with 78.
Grab the next digit (7) from the dividend, add it to 78, then carry on: 787 / 170

Moving on to step 3:
170 can be fit into 787 4 times, resulting in a remainder of 107.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Subtracting 680 from 787 leaves us with 107.
Grab the next digit (3) from the dividend, add it to 107, then carry on: 1073 / 170

Let's proceed to step 4:
When dividing 1073 by 170, we get 6 with a remainder of 53.
Use 6 as the next digit of our solution. 
Result so far: 46.0
Deduct 1020 from 1073 and we're left with 53.
Append the next digit (4) from the dividend to 53 and continue with: 534 / 170

Step 5:
170 can be fit into 534 3 times, resulting in a remainder of 24.
The number 3 becomes the next digit in our result. 
Result so far: 463.0
The remainder is 24 after subtracting 510 from 534.
Grab the next digit (1) from the dividend, add it to 24, then carry on: 241 / 170

On to step 6:
170 goes into 241 1 times with a remainder of 71.
Record the quotient 1 as the next digit in the result. 
Result so far: 4631.0
Deduct 170 from 241 and we're left with 71.
Fetch the next digit (6) from the dividend, attach it to 71 and continue: 716 / 170

Let's proceed to step 7:
170 goes into 716 4 times with a remainder of 36.
Put 4 as the next digit of the answer. 
Result so far: 46314.0
The remainder is 36 after subtracting 680 from 716.
Bring next digit (5) of the dividend behind the 36 and repeat the process: 365 / 170

Step 8:
170 can be fit into 365 2 times, resulting in a remainder of 25.
Use 2 as the next digit of our solution. 
Result so far: 463142.0
If we take 340 away from 365, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Step 9:
When dividing 250 by 170, we get 1 with a remainder of 80.
Use 1 as the next digit of our solution. 
Result so far: 463142.1
The remainder is 80 after subtracting 170 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Moving on to step 10:
800 divided by 170 is 4 with a remainder of 120.
Use 4 as the next digit of our solution. 
Result so far: 463142.14
Subtracting 680 from 800 leaves us with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Step 11:
If we divide 1200 by 170, we get 7 and a remainder of 10.
Record the quotient 7 as the next digit in the result. 
Result so far: 463142.147
If we subtract 1190 from 1200, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 12:
When dividing 100 by 170, we get 0 with a remainder of 100.
Put 0 as the next digit of the answer. 
Result so far: 463142.147
If we take 0 away from 100, we end up with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Let's proceed to step 13:
The number 170 fits into 1000 5 times, leaving a remainder of 150.
Record the quotient 5 as the next digit in the result. 
Result so far: 463142.14705
If we subtract 850 from 1000, we get 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Step 14:
1500 divided by 170 is 8 with a remainder of 140.
Put 8 as the next digit of the answer. 
Result so far: 463142.147058
If we take 1360 away from 1500, we end up with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Step 15:
1400 divided by 170 is 8 with a remainder of 40.
Write down 8 as next digit of the result. 
Result so far: 463142.1470588
Deduct 1360 from 1400 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

The final outcome is 463142.1470588, with a leftover of 4e-07.
