Let's divide 86454210 by 749
We want to figure out the number of times 86454210 can be divided by 749.

Step 1:
749 goes into 8 0 times with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 749

Advancing to step 2:
749 can be fit into 86 0 times, resulting in a remainder of 86.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 86 leaves us with 86.
Append the next digit (4) from the dividend to 86 and continue with: 864 / 749

Let's proceed to step 3:
749 can be fit into 864 1 times, resulting in a remainder of 115.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 749 from 864 leaves us with 115.
Append the next digit (5) from the dividend to 115 and continue with: 1155 / 749

Advancing to step 4:
When dividing 1155 by 749, we get 1 with a remainder of 406.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
Subtract 749 from 1155 to get 406.
Take the next digit (4) from the dividend and append it to 406, then repeat: 4064 / 749

Going ahead to step 5:
749 goes into 4064 5 times with a remainder of 319.
Put 5 as the next digit of the answer. 
Result so far: 115.0
Subtract 3745 from 4064 to get 319.
Include the next digit (2) from the dividend after 319, then repeat: 3192 / 749

Moving on to step 6:
If we divide 3192 by 749, we get 4 and a remainder of 196.
Put 4 as the next digit of the answer. 
Result so far: 1154.0
The remainder is 196 after subtracting 2996 from 3192.
Append the next digit (1) from the dividend to 196 and continue with: 1961 / 749

Going ahead to step 7:
When dividing 1961 by 749, we get 2 with a remainder of 463.
Put 2 as the next digit of the answer. 
Result so far: 11542.0
Deduct 1498 from 1961 and we're left with 463.
Include the next digit (0) from the dividend after 463, then repeat: 4630 / 749

Step 8:
749 goes into 4630 6 times with a remainder of 136.
Record the quotient 6 as the next digit in the result. 
Result so far: 115426.0
The remainder is 136 after subtracting 4494 from 4630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Let's proceed to step 9:
749 goes into 1360 1 times with a remainder of 611.
Record the quotient 1 as the next digit in the result. 
Result so far: 115426.1
Subtract 749 from 1360 to get 611.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6110, and continue the process.

Let's proceed to step 10:
If we divide 6110 by 749, we get 8 and a remainder of 118.
Use 8 as the next digit of our solution. 
Result so far: 115426.18
Subtracting 5992 from 6110 leaves us with 118.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

Going ahead to step 11:
749 goes into 1180 1 times with a remainder of 431.
The next digit of our result is 1. 
Result so far: 115426.181
If we subtract 749 from 1180, we get 431.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4310, and continue the process.

Going ahead to step 12:
The number 749 fits into 4310 5 times, leaving a remainder of 565.
The number 5 becomes the next digit in our result. 
Result so far: 115426.1815
If we subtract 3745 from 4310, we get 565.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5650, and continue the process.

Going ahead to step 13:
749 goes into 5650 7 times with a remainder of 407.
Put 7 as the next digit of the answer. 
Result so far: 115426.18157
Deduct 5243 from 5650 and we're left with 407.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4070, and continue the process.

Advancing to step 14:
When dividing 4070 by 749, we get 5 with a remainder of 325.
Record the quotient 5 as the next digit in the result. 
Result so far: 115426.181575
The remainder is 325 after subtracting 3745 from 4070.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3250, and continue the process.

On to step 15:
When dividing 3250 by 749, we get 4 with a remainder of 254.
The number 4 becomes the next digit in our result. 
Result so far: 115426.1815754
Deduct 2996 from 3250 and we're left with 254.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2540, and continue the process.

Going ahead to step 16:
2540 divided by 749 is 3 with a remainder of 293.
The number 3 becomes the next digit in our result. 
Result so far: 115426.18157543
The remainder is 293 after subtracting 2247 from 2540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2930, and continue the process.

In conclusion, the division gives 115426.18157543 with a balance of 2.93e-07.
