We divide 83845742 by 644
Our goal is to divide 83845742 by 644.

Advancing to step 1:
If we divide 8 by 644, we get 0 and a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Append the next digit (3) from the dividend to 8 and continue with: 83 / 644

Let's proceed to step 2:
The number 644 fits into 83 0 times, leaving a remainder of 83.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 83 leaves us with 83.
Bring next digit (8) of the dividend behind the 83 and repeat the process: 838 / 644

Going ahead to step 3:
644 goes into 838 1 times with a remainder of 194.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 644 from 838, we get 194.
Take the next digit (4) from the dividend and append it to 194, then repeat: 1944 / 644

Step 4:
1944 divided by 644 is 3 with a remainder of 12.
The next digit of our result is 3. 
Result so far: 13.0
Subtract 1932 from 1944 to get 12.
Bring next digit (5) of the dividend behind the 12 and repeat the process: 125 / 644

Step 5:
The number 644 fits into 125 0 times, leaving a remainder of 125.
Write down 0 as next digit of the result. 
Result so far: 130.0
Subtracting 0 from 125 leaves us with 125.
Fetch the next digit (7) from the dividend, attach it to 125 and continue: 1257 / 644

Advancing to step 6:
When dividing 1257 by 644, we get 1 with a remainder of 613.
Write down 1 as next digit of the result. 
Result so far: 1301.0
The remainder is 613 after subtracting 644 from 1257.
Include the next digit (4) from the dividend after 613, then repeat: 6134 / 644

Let's proceed to step 7:
If we divide 6134 by 644, we get 9 and a remainder of 338.
The number 9 becomes the next digit in our result. 
Result so far: 13019.0
The remainder is 338 after subtracting 5796 from 6134.
Grab the next digit (2) from the dividend, add it to 338, then carry on: 3382 / 644

Step 8:
When dividing 3382 by 644, we get 5 with a remainder of 162.
Write down 5 as next digit of the result. 
Result so far: 130195.0
If we take 3220 away from 3382, we end up with 162.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1620, and continue the process.

Let's proceed to step 9:
If we divide 1620 by 644, we get 2 and a remainder of 332.
Record the quotient 2 as the next digit in the result. 
Result so far: 130195.2
Deduct 1288 from 1620 and we're left with 332.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3320, and continue the process.

Advancing to step 10:
644 can be fit into 3320 5 times, resulting in a remainder of 100.
Put 5 as the next digit of the answer. 
Result so far: 130195.25
Subtracting 3220 from 3320 leaves us 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.

Step 11:
When dividing 1000 by 644, we get 1 with a remainder of 356.
Record the quotient 1 as the next digit in the result. 
Result so far: 130195.251
Subtract 644 from 1000 to get 356.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3560, and continue the process.

Advancing to step 12:
If we divide 3560 by 644, we get 5 and a remainder of 340.
Use 5 as the next digit of our solution. 
Result so far: 130195.2515
Subtracting 3220 from 3560 leaves us with 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Step 13:
3400 divided by 644 is 5 with a remainder of 180.
Write down 5 as next digit of the result. 
Result so far: 130195.25155
The remainder is 180 after subtracting 3220 from 3400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

The final outcome is 130195.25155, with a leftover of 0.00018.
