We divide 11613238 by 643
We're looking to find how many times 643 goes into 11613238.

On to step 1:
1 divided by 643 is 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Grab the next digit (1) from the dividend, add it to 1, then carry on: 11 / 643

Advancing to step 2:
643 can be fit into 11 0 times, resulting in a remainder of 11.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 11 and we're left with 11.
Take the next digit (6) from the dividend and append it to 11, then repeat: 116 / 643

Advancing to step 3:
When dividing 116 by 643, we get 0 with a remainder of 116.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 116 leaves us with 116.
Append the next digit (1) from the dividend to 116 and continue with: 1161 / 643

Moving on to step 4:
When dividing 1161 by 643, we get 1 with a remainder of 518.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 518 after subtracting 643 from 1161.
Include the next digit (3) from the dividend after 518, then repeat: 5183 / 643

Step 5:
When dividing 5183 by 643, we get 8 with a remainder of 39.
The next digit of our result is 8. 
Result so far: 18.0
The remainder is 39 after subtracting 5144 from 5183.
Include the next digit (2) from the dividend after 39, then repeat: 392 / 643

Advancing to step 6:
643 can be fit into 392 0 times, resulting in a remainder of 392.
Write down 0 as next digit of the result. 
Result so far: 180.0
If we subtract 0 from 392, we get 392.
Grab the next digit (3) from the dividend, add it to 392, then carry on: 3923 / 643

Going ahead to step 7:
643 can be fit into 3923 6 times, resulting in a remainder of 65.
Write down 6 as next digit of the result. 
Result so far: 1806.0
The remainder is 65 after subtracting 3858 from 3923.
Append the next digit (8) from the dividend to 65 and continue with: 658 / 643

Let's proceed to step 8:
658 divided by 643 is 1 with a remainder of 15.
Put 1 as the next digit of the answer. 
Result so far: 18061.0
Subtracting 643 from 658 leaves us 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.

Going ahead to step 9:
When dividing 150 by 643, we get 0 with a remainder of 150.
Record the quotient 0 as the next digit in the result. 
Result so far: 18061.0
The remainder is 150 after subtracting 0 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Let's proceed to step 10:
The number 643 fits into 1500 2 times, leaving a remainder of 214.
Put 2 as the next digit of the answer. 
Result so far: 18061.02
If we subtract 1286 from 1500, we get 214.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2140, and continue the process.

Moving on to step 11:
When dividing 2140 by 643, we get 3 with a remainder of 211.
Record the quotient 3 as the next digit in the result. 
Result so far: 18061.023
Deduct 1929 from 2140 and we're left with 211.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2110, and continue the process.

Moving on to step 12:
If we divide 2110 by 643, we get 3 and a remainder of 181.
Put 3 as the next digit of the answer. 
Result so far: 18061.0233
The remainder is 181 after subtracting 1929 from 2110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1810, and continue the process.

The final outcome is 18061.0233, with a leftover of 0.00181.
