We're dividing 71820643 by 637 
Our goal is to divide 71820643 by 637.

Moving on to step 1:
If we divide 7 by 637, we get 0 and a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Bring next digit (1) of the dividend behind the 7 and repeat the process: 71 / 637

Step 2:
71 divided by 637 is 0 with a remainder of 71.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 71, we get 71.
Grab the next digit (8) from the dividend, add it to 71, then carry on: 718 / 637

Advancing to step 3:
637 goes into 718 1 times with a remainder of 81.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 637 from 718 leaves us with 81.
Append the next digit (2) from the dividend to 81 and continue with: 812 / 637

Going ahead to step 4:
If we divide 812 by 637, we get 1 and a remainder of 175.
Put 1 as the next digit of the answer. 
Result so far: 11.0
Subtracting 637 from 812 leaves us with 175.
Take the next digit (0) from the dividend and append it to 175, then repeat: 1750 / 637

Moving on to step 5:
When dividing 1750 by 637, we get 2 with a remainder of 476.
The number 2 becomes the next digit in our result. 
Result so far: 112.0
The remainder is 476 after subtracting 1274 from 1750.
Append the next digit (6) from the dividend to 476 and continue with: 4766 / 637

Advancing to step 6:
When dividing 4766 by 637, we get 7 with a remainder of 307.
Write down 7 as next digit of the result. 
Result so far: 1127.0
If we subtract 4459 from 4766, we get 307.
Bring next digit (4) of the dividend behind the 307 and repeat the process: 3074 / 637

Moving on to step 7:
3074 divided by 637 is 4 with a remainder of 526.
Use 4 as the next digit of our solution. 
Result so far: 11274.0
Subtract 2548 from 3074 to get 526.
Bring next digit (3) of the dividend behind the 526 and repeat the process: 5263 / 637

Let's proceed to step 8:
When dividing 5263 by 637, we get 8 with a remainder of 167.
Use 8 as the next digit of our solution. 
Result so far: 112748.0
If we take 5096 away from 5263, we end up with 167.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1670, and continue the process.

Moving on to step 9:
637 goes into 1670 2 times with a remainder of 396.
Record the quotient 2 as the next digit in the result. 
Result so far: 112748.2
If we take 1274 away from 1670, we end up with 396.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3960, and continue the process.

Advancing to step 10:
637 can be fit into 3960 6 times, resulting in a remainder of 138.
Put 6 as the next digit of the answer. 
Result so far: 112748.26
If we subtract 3822 from 3960, we get 138.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

Advancing to step 11:
637 goes into 1380 2 times with a remainder of 106.
The next digit of our result is 2. 
Result so far: 112748.262
The remainder is 106 after subtracting 1274 from 1380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Moving on to step 12:
1060 divided by 637 is 1 with a remainder of 423.
Write down 1 as next digit of the result. 
Result so far: 112748.2621
Subtract 637 from 1060 to get 423.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4230, and continue the process.

On to step 13:
637 can be fit into 4230 6 times, resulting in a remainder of 408.
The next digit of our result is 6. 
Result so far: 112748.26216
Subtract 3822 from 4230 to get 408.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4080, and continue the process.

Step 14:
637 can be fit into 4080 6 times, resulting in a remainder of 258.
Use 6 as the next digit of our solution. 
Result so far: 112748.262166
If we take 3822 away from 4080, we end up with 258.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2580, and continue the process.

The final outcome is 112748.262166, with a leftover of 2.58e-05.
