We're dividing 86370434 by 705 
We're looking to find how many times 705 goes into 86370434.

On to step 1:
705 can be fit into 8 0 times, resulting in a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Take the next digit (6) from the dividend and append it to 8, then repeat: 86 / 705

Step 2:
705 goes into 86 0 times with a remainder of 86.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 86, we end up with 86.
Append the next digit (3) from the dividend to 86 and continue with: 863 / 705

Step 3:
If we divide 863 by 705, we get 1 and a remainder of 158.
The next digit of our result is 1. 
Result so far: 1.0
If we take 705 away from 863, we end up with 158.
Fetch the next digit (7) from the dividend, attach it to 158 and continue: 1587 / 705

Let's proceed to step 4:
When dividing 1587 by 705, we get 2 with a remainder of 177.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
Subtract 1410 from 1587 to get 177.
Take the next digit (0) from the dividend and append it to 177, then repeat: 1770 / 705

On to step 5:
If we divide 1770 by 705, we get 2 and a remainder of 360.
Put 2 as the next digit of the answer. 
Result so far: 122.0
If we subtract 1410 from 1770, we get 360.
Grab the next digit (4) from the dividend, add it to 360, then carry on: 3604 / 705

Advancing to step 6:
If we divide 3604 by 705, we get 5 and a remainder of 79.
Put 5 as the next digit of the answer. 
Result so far: 1225.0
Deduct 3525 from 3604 and we're left with 79.
Include the next digit (3) from the dividend after 79, then repeat: 793 / 705

Moving on to step 7:
When dividing 793 by 705, we get 1 with a remainder of 88.
The number 1 becomes the next digit in our result. 
Result so far: 12251.0
Deduct 705 from 793 and we're left with 88.
Take the next digit (4) from the dividend and append it to 88, then repeat: 884 / 705

On to step 8:
When dividing 884 by 705, we get 1 with a remainder of 179.
Use 1 as the next digit of our solution. 
Result so far: 122511.0
If we take 705 away from 884, we end up with 179.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1790, and continue the process.

Step 9:
705 goes into 1790 2 times with a remainder of 380.
Write down 2 as next digit of the result. 
Result so far: 122511.2
The remainder is 380 after subtracting 1410 from 1790.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

On to step 10:
705 can be fit into 3800 5 times, resulting in a remainder of 275.
Put 5 as the next digit of the answer. 
Result so far: 122511.25
If we subtract 3525 from 3800, we get 275.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2750, and continue the process.

Going ahead to step 11:
If we divide 2750 by 705, we get 3 and a remainder of 635.
Write down 3 as next digit of the result. 
Result so far: 122511.253
The remainder is 635 after subtracting 2115 from 2750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6350, and continue the process.

Moving on to step 12:
705 can be fit into 6350 9 times, resulting in a remainder of 5.
Record the quotient 9 as the next digit in the result. 
Result so far: 122511.2539
Deduct 6345 from 6350 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 13:
705 can be fit into 50 0 times, resulting in a remainder of 50.
Put 0 as the next digit of the answer. 
Result so far: 122511.2539
If we take 0 away from 50, we end up 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.

Moving on to step 14:
The number 705 fits into 500 0 times, leaving a remainder of 500.
The number 0 becomes the next digit in our result. 
Result so far: 122511.2539
If we subtract 0 from 500, we get 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

The final outcome is 122511.2539, with a leftover of 5e-05.
