We're dividing 53693209 by 642 
We're looking to find how many times 642 goes into 53693209.

Moving on to step 1:
642 goes into 5 0 times with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Include the next digit (3) from the dividend after 5, then repeat: 53 / 642

Let's proceed to step 2:
53 divided by 642 is 0 with a remainder of 53.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 53 leaves us with 53.
Bring next digit (6) of the dividend behind the 53 and repeat the process: 536 / 642

On to step 3:
When dividing 536 by 642, we get 0 with a remainder of 536.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 536 after subtracting 0 from 536.
Take the next digit (9) from the dividend and append it to 536, then repeat: 5369 / 642

Let's proceed to step 4:
642 goes into 5369 8 times with a remainder of 233.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Subtract 5136 from 5369 to get 233.
Append the next digit (3) from the dividend to 233 and continue with: 2333 / 642

Moving on to step 5:
If we divide 2333 by 642, we get 3 and a remainder of 407.
The number 3 becomes the next digit in our result. 
Result so far: 83.0
Subtract 1926 from 2333 to get 407.
Grab the next digit (2) from the dividend, add it to 407, then carry on: 4072 / 642

Let's proceed to step 6:
When dividing 4072 by 642, we get 6 with a remainder of 220.
Put 6 as the next digit of the answer. 
Result so far: 836.0
If we subtract 3852 from 4072, we get 220.
Fetch the next digit (0) from the dividend, attach it to 220 and continue: 2200 / 642

Going ahead to step 7:
2200 divided by 642 is 3 with a remainder of 274.
Write down 3 as next digit of the result. 
Result so far: 8363.0
The remainder is 274 after subtracting 1926 from 2200.
Take the next digit (9) from the dividend and append it to 274, then repeat: 2749 / 642

Going ahead to step 8:
642 can be fit into 2749 4 times, resulting in a remainder of 181.
Record the quotient 4 as the next digit in the result. 
Result so far: 83634.0
If we take 2568 away from 2749, we end up with 181.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1810, and continue the process.

Advancing to step 9:
642 goes into 1810 2 times with a remainder of 526.
Use 2 as the next digit of our solution. 
Result so far: 83634.2
If we take 1284 away from 1810, we end up with 526.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5260, and continue the process.

Let's proceed to step 10:
When dividing 5260 by 642, we get 8 with a remainder of 124.
Write down 8 as next digit of the result. 
Result so far: 83634.28
Subtracting 5136 from 5260 leaves us with 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

On to step 11:
642 can be fit into 1240 1 times, resulting in a remainder of 598.
The number 1 becomes the next digit in our result. 
Result so far: 83634.281
If we take 642 away from 1240, we end up with 598.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5980, and continue the process.

Advancing to step 12:
642 goes into 5980 9 times with a remainder of 202.
Write down 9 as next digit of the result. 
Result so far: 83634.2819
Subtracting 5778 from 5980 leaves us with 202.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2020, and continue the process.

Let's proceed to step 13:
642 can be fit into 2020 3 times, resulting in a remainder of 94.
Put 3 as the next digit of the answer. 
Result so far: 83634.28193
Deduct 1926 from 2020 and we're left with 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Let's proceed to step 14:
642 can be fit into 940 1 times, resulting in a remainder of 298.
Put 1 as the next digit of the answer. 
Result so far: 83634.281931
Subtract 642 from 940 to get 298.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2980, and continue the process.

On to step 15:
642 goes into 2980 4 times with a remainder of 412.
The number 4 becomes the next digit in our result. 
Result so far: 83634.2819314
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.

Advancing to step 16:
If we divide 4120 by 642, we get 6 and a remainder of 268.
Use 6 as the next digit of our solution. 
Result so far: 83634.28193146
Deduct 3852 from 4120 and we're left with 268.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2680, and continue the process.

After the division, we end up with 83634.28193146 and a remainder of 2.68e-07.
