85065298 divided by 642 
We want to divide 85065298 by 642.

Let's proceed to step 1:
642 can be fit into 8 0 times, resulting in a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Append the next digit (5) from the dividend to 8 and continue with: 85 / 642

Let's proceed to step 2:
85 divided by 642 is 0 with a remainder of 85.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 85 leaves us with 85.
Bring next digit (0) of the dividend behind the 85 and repeat the process: 850 / 642

Step 3:
850 divided by 642 is 1 with a remainder of 208.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 642 away from 850, we end up with 208.
Bring next digit (6) of the dividend behind the 208 and repeat the process: 2086 / 642

Going ahead to step 4:
The number 642 fits into 2086 3 times, leaving a remainder of 160.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
Subtracting 1926 from 2086 leaves us with 160.
Take the next digit (5) from the dividend and append it to 160, then repeat: 1605 / 642

Advancing to step 5:
When dividing 1605 by 642, we get 2 with a remainder of 321.
Record the quotient 2 as the next digit in the result. 
Result so far: 132.0
Deduct 1284 from 1605 and we're left with 321.
Append the next digit (2) from the dividend to 321 and continue with: 3212 / 642

Let's proceed to step 6:
If we divide 3212 by 642, we get 5 and a remainder of 2.
The number 5 becomes the next digit in our result. 
Result so far: 1325.0
Subtract 3210 from 3212 to get 2.
Append the next digit (9) from the dividend to 2 and continue with: 29 / 642

Advancing to step 7:
The number 642 fits into 29 0 times, leaving a remainder of 29.
The number 0 becomes the next digit in our result. 
Result so far: 13250.0
If we take 0 away from 29, we end up with 29.
Bring next digit (8) of the dividend behind the 29 and repeat the process: 298 / 642

Advancing to step 8:
642 goes into 298 0 times with a remainder of 298.
The next digit of our result is 0. 
Result so far: 132500.0
The remainder is 298 after subtracting 0 from 298.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2980, and continue the process.

Going ahead to step 9:
642 can be fit into 2980 4 times, resulting in a remainder of 412.
Write down 4 as next digit of the result. 
Result so far: 132500.4
Subtracting 2568 from 2980 leaves us with 412.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4120, and continue the process.

On to step 10:
4120 divided by 642 is 6 with a remainder of 268.
Put 6 as the next digit of the answer. 
Result so far: 132500.46
Subtract 3852 from 4120 to get 268.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2680, and continue the process.

Going ahead to step 11:
642 goes into 2680 4 times with a remainder of 112.
Put 4 as the next digit of the answer. 
Result so far: 132500.464
Subtracting 2568 from 2680 leaves us with 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Advancing to step 12:
The number 642 fits into 1120 1 times, leaving a remainder of 478.
Use 1 as the next digit of our solution. 
Result so far: 132500.4641
If we subtract 642 from 1120, we get 478.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4780, and continue the process.

On to step 13:
642 can be fit into 4780 7 times, resulting in a remainder of 286.
The next digit of our result is 7. 
Result so far: 132500.46417
If we subtract 4494 from 4780, we get 286.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2860, and continue the process.

Going ahead to step 14:
642 can be fit into 2860 4 times, resulting in a remainder of 292.
Use 4 as the next digit of our solution. 
Result so far: 132500.464174
If we subtract 2568 from 2860, we get 292.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2920, and continue the process.

Going ahead to step 15:
If we divide 2920 by 642, we get 4 and a remainder of 352.
Put 4 as the next digit of the answer. 
Result so far: 132500.4641744
Subtract 2568 from 2920 to get 352.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

The final outcome is 132500.4641744, with a leftover of 3.52e-06.
