We divide 642991 by 49
Our goal is to divide 642991 by 49.

Step 1:
6 divided by 49 is 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Append the next digit (4) from the dividend to 6 and continue with: 64 / 49

On to step 2:
When dividing 64 by 49, we get 1 with a remainder of 15.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 49 from 64 leaves us with 15.
Fetch the next digit (2) from the dividend, attach it to 15 and continue: 152 / 49

Step 3:
The number 49 fits into 152 3 times, leaving a remainder of 5.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
Subtracting 147 from 152 leaves us with 5.
Grab the next digit (9) from the dividend, add it to 5, then carry on: 59 / 49

Step 4:
If we divide 59 by 49, we get 1 and a remainder of 10.
Record the quotient 1 as the next digit in the result. 
Result so far: 131.0
Deduct 49 from 59 and we're left with 10.
Take the next digit (9) from the dividend and append it to 10, then repeat: 109 / 49

Step 5:
109 divided by 49 is 2 with a remainder of 11.
The next digit of our result is 2. 
Result so far: 1312.0
The remainder is 11 after subtracting 98 from 109.
Take the next digit (1) from the dividend and append it to 11, then repeat: 111 / 49

Advancing to step 6:
49 can be fit into 111 2 times, resulting in a remainder of 13.
Use 2 as the next digit of our solution. 
Result so far: 13122.0
If we take 98 away from 111, we end up with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Let's proceed to step 7:
When dividing 130 by 49, we get 2 with a remainder of 32.
Write down 2 as next digit of the result. 
Result so far: 13122.2
Subtract 98 from 130 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 8:
The number 49 fits into 320 6 times, leaving a remainder of 26.
The next digit of our result is 6. 
Result so far: 13122.26
If we subtract 294 from 320, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Going ahead to step 9:
The number 49 fits into 260 5 times, leaving a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 13122.265
Deduct 245 from 260 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 10:
If we divide 150 by 49, we get 3 and a remainder of 3.
The number 3 becomes the next digit in our result. 
Result so far: 13122.2653
If we subtract 147 from 150, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 11:
If we divide 30 by 49, we get 0 and a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 13122.2653
Subtracting 0 from 30 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 12:
The number 49 fits into 300 6 times, leaving a remainder of 6.
The next digit of our result is 6. 
Result so far: 13122.265306
Deduct 294 from 300 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 13:
60 divided by 49 is 1 with a remainder of 11.
The next digit of our result is 1. 
Result so far: 13122.2653061
The remainder is 11 after subtracting 49 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Going ahead to step 14:
The number 49 fits into 110 2 times, leaving a remainder of 12.
Use 2 as the next digit of our solution. 
Result so far: 13122.26530612
Subtract 98 from 110 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

In conclusion, the division gives 13122.26530612 with a balance of 1.2e-08.
