We divide 71418547 by 643
Our goal is to divide 71418547 by 643.

Let's proceed to step 1:
643 goes into 7 0 times with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Append the next digit (1) from the dividend to 7 and continue with: 71 / 643

Going ahead to step 2:
When dividing 71 by 643, we get 0 with a remainder of 71.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 71 leaves us with 71.
Bring next digit (4) of the dividend behind the 71 and repeat the process: 714 / 643

Going ahead to step 3:
643 can be fit into 714 1 times, resulting in a remainder of 71.
The next digit of our result is 1. 
Result so far: 1.0
If we take 643 away from 714, we end up with 71.
Grab the next digit (1) from the dividend, add it to 71, then carry on: 711 / 643

Let's proceed to step 4:
If we divide 711 by 643, we get 1 and a remainder of 68.
The next digit of our result is 1. 
Result so far: 11.0
Subtract 643 from 711 to get 68.
Fetch the next digit (8) from the dividend, attach it to 68 and continue: 688 / 643

Let's proceed to step 5:
The number 643 fits into 688 1 times, leaving a remainder of 45.
Use 1 as the next digit of our solution. 
Result so far: 111.0
Subtract 643 from 688 to get 45.
Append the next digit (5) from the dividend to 45 and continue with: 455 / 643

Advancing to step 6:
The number 643 fits into 455 0 times, leaving a remainder of 455.
Write down 0 as next digit of the result. 
Result so far: 1110.0
If we take 0 away from 455, we end up with 455.
Take the next digit (4) from the dividend and append it to 455, then repeat: 4554 / 643

Going ahead to step 7:
4554 divided by 643 is 7 with a remainder of 53.
Put 7 as the next digit of the answer. 
Result so far: 11107.0
Deduct 4501 from 4554 and we're left with 53.
Bring next digit (7) of the dividend behind the 53 and repeat the process: 537 / 643

Let's proceed to step 8:
If we divide 537 by 643, we get 0 and a remainder of 537.
Put 0 as the next digit of the answer. 
Result so far: 111070.0
If we take 0 away from 537, we end up with 537.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5370, and continue the process.

Advancing to step 9:
When dividing 5370 by 643, we get 8 with a remainder of 226.
The number 8 becomes the next digit in our result. 
Result so far: 111070.8
The remainder is 226 after subtracting 5144 from 5370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2260, and continue the process.

Let's proceed to step 10:
If we divide 2260 by 643, we get 3 and a remainder of 331.
Use 3 as the next digit of our solution. 
Result so far: 111070.83
Deduct 1929 from 2260 and we're left with 331.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3310, and continue the process.

Moving on to step 11:
643 goes into 3310 5 times with a remainder of 95.
Put 5 as the next digit of the answer. 
Result so far: 111070.835
If we take 3215 away from 3310, we end up with 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

Moving on to step 12:
643 can be fit into 950 1 times, resulting in a remainder of 307.
Use 1 as the next digit of our solution. 
Result so far: 111070.8351
If we take 643 away from 950, we end up with 307.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3070, and continue the process.

On to step 13:
643 goes into 3070 4 times with a remainder of 498.
Record the quotient 4 as the next digit in the result. 
Result so far: 111070.83514
Subtracting 2572 from 3070 leaves us with 498.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4980, and continue the process.

Moving on to step 14:
643 goes into 4980 7 times with a remainder of 479.
Write down 7 as next digit of the result. 
Result so far: 111070.835147
Subtract 4501 from 4980 to get 479.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4790, and continue the process.

Step 15:
643 goes into 4790 7 times with a remainder of 289.
Put 7 as the next digit of the answer. 
Result so far: 111070.8351477
Subtracting 4501 from 4790 leaves us with 289.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2890, and continue the process.

In conclusion, the division gives 111070.8351477 with a balance of 2.89e-06.
