45639214 ÷ 861 
We're looking to find how many times 861 goes into 45639214.

Step 1:
The number 861 fits into 4 0 times, leaving a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Take the next digit (5) from the dividend and append it to 4, then repeat: 45 / 861

Step 2:
45 divided by 861 is 0 with a remainder of 45.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 45, we end up with 45.
Grab the next digit (6) from the dividend, add it to 45, then carry on: 456 / 861

Step 3:
861 can be fit into 456 0 times, resulting in a remainder of 456.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 456 after subtracting 0 from 456.
Append the next digit (3) from the dividend to 456 and continue with: 4563 / 861

Advancing to step 4:
861 goes into 4563 5 times with a remainder of 258.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Deduct 4305 from 4563 and we're left with 258.
Take the next digit (9) from the dividend and append it to 258, then repeat: 2589 / 861

Let's proceed to step 5:
861 can be fit into 2589 3 times, resulting in a remainder of 6.
The next digit of our result is 3. 
Result so far: 53.0
Deduct 2583 from 2589 and we're left with 6.
Grab the next digit (2) from the dividend, add it to 6, then carry on: 62 / 861

Moving on to step 6:
When dividing 62 by 861, we get 0 with a remainder of 62.
Record the quotient 0 as the next digit in the result. 
Result so far: 530.0
Subtracting 0 from 62 leaves us with 62.
Append the next digit (1) from the dividend to 62 and continue with: 621 / 861

Let's proceed to step 7:
If we divide 621 by 861, we get 0 and a remainder of 621.
Record the quotient 0 as the next digit in the result. 
Result so far: 5300.0
Subtract 0 from 621 to get 621.
Grab the next digit (4) from the dividend, add it to 621, then carry on: 6214 / 861

Step 8:
When dividing 6214 by 861, we get 7 with a remainder of 187.
Put 7 as the next digit of the answer. 
Result so far: 53007.0
If we subtract 6027 from 6214, we get 187.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1870, and continue the process.

On to step 9:
861 goes into 1870 2 times with a remainder of 148.
Put 2 as the next digit of the answer. 
Result so far: 53007.2
Subtract 1722 from 1870 to get 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

Advancing to step 10:
When dividing 1480 by 861, we get 1 with a remainder of 619.
Use 1 as the next digit of our solution. 
Result so far: 53007.21
Deduct 861 from 1480 and we're left with 619.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6190, and continue the process.

On to step 11:
861 goes into 6190 7 times with a remainder of 163.
Write down 7 as next digit of the result. 
Result so far: 53007.217
The remainder is 163 after subtracting 6027 from 6190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1630, and continue the process.

Step 12:
1630 divided by 861 is 1 with a remainder of 769.
Record the quotient 1 as the next digit in the result. 
Result so far: 53007.2171
Deduct 861 from 1630 and we're left with 769.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7690, and continue the process.

Moving on to step 13:
If we divide 7690 by 861, we get 8 and a remainder of 802.
Write down 8 as next digit of the result. 
Result so far: 53007.21718
If we take 6888 away from 7690, we end up with 802.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8020, and continue the process.

Moving on to step 14:
861 can be fit into 8020 9 times, resulting in a remainder of 271.
Use 9 as the next digit of our solution. 
Result so far: 53007.217189
Subtracting 7749 from 8020 leaves us with 271.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2710, and continue the process.

On to step 15:
861 goes into 2710 3 times with a remainder of 127.
Write down 3 as next digit of the result. 
Result so far: 53007.2171893
Deduct 2583 from 2710 and we're left with 127.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1270, and continue the process.

On to step 16:
When dividing 1270 by 861, we get 1 with a remainder of 409.
Write down 1 as next digit of the result. 
Result so far: 53007.21718931
Deduct 861 from 1270 and we're left with 409.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4090, and continue the process.

In conclusion, the division gives 53007.21718931 with a balance of 4.09e-07.
