78612426 divided by 170 
We're looking to find how many times 170 goes into 78612426.

Step 1:
7 divided by 170 is 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Grab the next digit (8) from the dividend, add it to 7, then carry on: 78 / 170

Moving on to step 2:
The number 170 fits into 78 0 times, leaving a remainder of 78.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 78, we get 78.
Append the next digit (6) from the dividend to 78 and continue with: 786 / 170

Moving on to step 3:
170 goes into 786 4 times with a remainder of 106.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Deduct 680 from 786 and we're left with 106.
Grab the next digit (1) from the dividend, add it to 106, then carry on: 1061 / 170

On to step 4:
The number 170 fits into 1061 6 times, leaving a remainder of 41.
Record the quotient 6 as the next digit in the result. 
Result so far: 46.0
If we take 1020 away from 1061, we end up with 41.
Fetch the next digit (2) from the dividend, attach it to 41 and continue: 412 / 170

On to step 5:
170 goes into 412 2 times with a remainder of 72.
Record the quotient 2 as the next digit in the result. 
Result so far: 462.0
The remainder is 72 after subtracting 340 from 412.
Bring next digit (4) of the dividend behind the 72 and repeat the process: 724 / 170

Advancing to step 6:
724 divided by 170 is 4 with a remainder of 44.
Put 4 as the next digit of the answer. 
Result so far: 4624.0
Subtracting 680 from 724 leaves us with 44.
Fetch the next digit (2) from the dividend, attach it to 44 and continue: 442 / 170

Step 7:
170 can be fit into 442 2 times, resulting in a remainder of 102.
Record the quotient 2 as the next digit in the result. 
Result so far: 46242.0
Subtract 340 from 442 to get 102.
Take the next digit (6) from the dividend and append it to 102, then repeat: 1026 / 170

Step 8:
The number 170 fits into 1026 6 times, leaving a remainder of 6.
Record the quotient 6 as the next digit in the result. 
Result so far: 462426.0
Subtracting 1020 from 1026 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 9:
If we divide 60 by 170, we get 0 and a remainder of 60.
Put 0 as the next digit of the answer. 
Result so far: 462426.0
Deduct 0 from 60 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 10:
If we divide 600 by 170, we get 3 and a remainder of 90.
Put 3 as the next digit of the answer. 
Result so far: 462426.03
If we subtract 510 from 600, we get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

On to step 11:
900 divided by 170 is 5 with a remainder of 50.
Record the quotient 5 as the next digit in the result. 
Result so far: 462426.035
Deduct 850 from 900 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 12:
170 can be fit into 500 2 times, resulting in a remainder of 160.
Put 2 as the next digit of the answer. 
Result so far: 462426.0352
If we subtract 340 from 500, we get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Going ahead to step 13:
The number 170 fits into 1600 9 times, leaving a remainder of 70.
Put 9 as the next digit of the answer. 
Result so far: 462426.03529
If we take 1530 away from 1600, we end up with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Step 14:
170 goes into 700 4 times with a remainder of 20.
Put 4 as the next digit of the answer. 
Result so far: 462426.035294
The remainder is 20 after subtracting 680 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 15:
200 divided by 170 is 1 with a remainder of 30.
The number 1 becomes the next digit in our result. 
Result so far: 462426.0352941
Deduct 170 from 200 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 16:
170 can be fit into 300 1 times, resulting in a remainder of 130.
The next digit of our result is 1. 
Result so far: 462426.03529411
Subtracting 170 from 300 leaves us with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

The final outcome is 462426.03529411, with a leftover of 1.3e-07.
